Speakers

How are the front grills removed from the ceiling and wall speakers?

 

In-wall and in-ceiling speaker grills are pressure fit and rely on contact of both inside and outside surfaces to hold it in place. If the grill becomes warped/distorted, it will be more difficult to remove or reinstall. Proper care should be taken when removing or reinstalling it.

 

 

 

If the speaker is not yet installed:

While looking at the rear of the speaker assembly, rotate all mounting legs outward into their free position and then push them forward, one by one, towards the front of the speaker assembly. This will push the attached screws forward to meet the inside of the grill and push it out from behind. When a section of the grill starts to move out, apply pressure to one of the other mounting legs until the grill is free.

 

 

 

If the speaker is installed:

We suggest the use of a small hook tool (resembling a dentist's pick) or other small, pointed tool. A bent paper clip or stiff wire will work as well. Hook the device into a hole in the metal mesh of the grill near a corner (In-Wall) or edge (In-Ceiling) and gently pull it towards you. Once it moves a little, change the position of the hook to pull out other sections. For rectangular speakers, go to the next corner, and repeat. For round speaker, move your hook about four inches at a time, and repeat all away around or until the grill is free.

 

*Attempting to remove the grill by prying will likely result in damage.

 

 

 

Can In-Ceiling speakers be used in the wall and In-Wall speakers in the ceiling?

 

Absolutely! You can install either type in any in-wall or in-ceiling applications. Footprint size and aesthetics may be a consideration. In-Ceiling speakers are smaller and have a smaller footprint (or overall dimension). However, the larger In-Wall speakers will mount safely to wall or ceiling. Either speaker can be used for either application.

 

 

 

Are there general guidelines as to how many speakers to install in a room and where to position them?

 

 

 

Typically, most rooms will only need a single pair of speakers to provide adequate coverage for background music or moderate listening volumes. In larger rooms, such as a garage or recreation room, multiple pairs should be spaced about 10 to 12 feet apart. Also, speakers should be positioned at least 3 to 4 feet from adjacent walls (to avoid sound bounce back or deflection).

 

 

 

In a home theater installation, In-Wall and In-Ceiling speakers should be positioned according to standard guidelines in order to direct sound towards the viewing/listening area.

 

Are mounting brackets (new construction) required to install In-Ceiling and In-Wall speakers?

 

It depends on your installation needs. Our in-wall and in-ceiling speakers are equipped with their own mounting system and will install without additional brackets. They will mount directly to sheetrock/drywall with the “L” shaped mounting legs that clamp to the backside of the wallboard.

 

 

 

The benefit of brackets is to indicate pre-determined speaker locations at the time the drywall work is done. New construction brackets provide a template that allows sheet-rock or dry-wall to be cut for the speakers upon installation.

 

 

 

Brackets will provide some additional structural support as they are rugged and mount directly to studs or joists.

 

How should the New Construction brackets be oriented, with the lip facing in or out?

 

The brackets can be installed either way, but are commonly oriented with the lip facing out in order to provide a neater installation and a little extra bracing inside the drywall cut-out.

 

What is the purpose of a subwoofer?

 

A subwoofer's role is reproducing low frequency audio (bass). Subwoofers greatly enhance the bass response of a system, and are especially effective in a home theater environment. Since the recent trend away from larger tower speakers towards smaller satellite and in-wall speakers, subwoofers have become an important part of a complete system for full spectrum audio reproduction.

 

 

 

I get a loud “hum” through my Audiosource powered subwoofer. What could be the problem?

 

 

 

In most cases, if you hear audio program along with the “hum” through the subwoofer, there is probably a “ground loop” problem in your system.

 

 

 

This can usually be remedied with one of the following solutions:

 

 

 

Make certain that both the receiver and subwoofer are plugged into outlets that share a common circuit breaker.

 

 

 

Temporarily disconnect the coaxial cable (Cable TV, Satellite connection) that is coming in from the outside. In many cases there is a weak ground present which can cause noise. If the noise is gone when the cable is disconnected, your cable service is probably not equipped with a grounding block. A coaxial grounding block can be purchased from a local electronics store.

 

 

 

Temporarily run a small wire between the chassis metal of your source unit to the chassis metal on the rear panel of the subwoofer. If this alleviates the noise, you can run a permanent wire between the receiver and the subwoofer amplifier, connected to a chassis screw on each unit. Many receivers have a provision for this with a thumbscrew labeled as GND.

 

 

 

Install a 2-prong plug adaptor on the end of the subwoofer's 3-prong AC plug. This eliminates the ground prong and will cut the hum completely in most cases. This is not a recommended solution in electrical storm prone areas.

 

 

 

How do I connect your In-Wall Subwoofers?

 

 

 

In most cases, an additional power amplifier will be needed to power the passive In-Wall subwoofers. A modular mono-block amplifier or a bridged stereo amplifier will work well. Use the “subwoofer-out” RCA jack or LFE output on your receiver to provide signal to the input of a power amplifier. Connect the speaker output on the power amp to the In-Wall subwoofer(s).

 

 

 

What is series and parallel wiring?

 

Parallel wiring is a wiring scheme that connects two or more components by connecting all positive terminals together and all negative terminals together. The load impedance drops when speakers are wired in this fashion. The greater the number of speakers that are connected in parallel, the lower the total impedance. In general, amplifier output increases with lower load impedances.

 

 

 

The number of speakers that can be connected in parallel is limited by the minimum load impedance of the receiver/amplifier that powers the system. Typically, 6 or 8 ohms is the minimum load impedance for receivers. Most power amplifiers are capable of operating at 4 ohms or 2 ohms.

 

 

 

Series wiring has the opposite effect of parallel wiring on the total impedance. The greater the number of speakers that are connected in series, the higher the total impedance. With series wiring, components are connected in such a way that current flows through the first component before it can flow through the second component. The resulting impedance is the sum of the impedances of all components connected in series.

 

 

 

A common reason for wiring speakers in series is to raise the impedance to a level that is acceptable for the receiver/amplifier (i.e two pairs of 4 ohm speakers / a pair connected to each channel of a receiver. Each pair of 4 ohm speakers is wired in series for 8 ohms per channel operation).

Electronics

Which inputs are used on the line-source switching amplifiers if there is only one line source, Line 1 or Line 2 inputs?

 

 

 

If only one source is being used, connect the line signal to the Line 2 inputs. Line 2 should be considered the primary input for continuous use audio program. Input devices that are used on an occasional basis should be connected to the Line 1 inputs.

 

 

 

How many speakers can be connected to one amplifier?

 

 

 

That depends on how much power you need to have available for each speaker. For background music or moderate listening levels you should provide at least 15 watts for each speaker. Then it is just a matter of doing the math. Example: Amplifier output=80 watts per channel. 80 watts divided by 15 watts = 5.3 or (5) pairs of speakers. To provide at least 15 watts to each speaker, the number of speakers should not exceed (5) pair. If more speakers are desired, additional amplifiers are recommended. If more power to each speaker is required, than a higher output amplifier or additional amplifiers are recommended.

 

 

 

 

 

 

The other consideration is impedance. 4 ohms is the minimum recommended impedance for most home audio power amplifiers. For most receivers, 8 ohms is the minimum speaker impedance. Without the use of impedance matching/balancing devices, the number of 8 ohm speakers (in parallel) that can be connected to a power amplifier is (2) pair.

 

 

 

How much power is needed for the number of speakers I have?

 

 

 

That depends on the recommended minimum power for the speaker (if indicated) or the amount of power desired for each speaker. For background music and moderate listening levels, multiply 15 watts X the number of speaker pairs in the system. Example: 8 pairs of speakers X 15 watts per speaker = 120 watts. The amplifier should have at least 120 watts (continuous) power per channel.

 

 

 

My amplifier makes a clicking sound inside when the audio program is at a low level. The audio also cuts in and out. What is causing this?

 

 

 

If you are using the Line 1 inputs on the amp and there is only one source connected, remove the RCA cables from the Line 1 inputs and connect to the Line 2 inputs. Line 2 is the primary input for continuous use audio program.

 

 

 

 

 

 

If you have two sources connected to the amp, and you hear clicking, or the audio cuts out between music tracks when the Line 1 device is active, try increasing the “delay time” on the rear if the amplifier (if feature is provided on your model).

 

 

 

There is very little or no sound coming from the speakers. What is the problem?

 

 

 

Check to ensure that the Master Gain levels on the rear of amplifier are adjusted up, as they are usually set to minimum from the factory. Set the master levels between the 12 and 3 o'clock position.

 

 

 

The volume on the amplifier is at maximum and the volume from the speakers is still too low. What could the problem be?

 

 

 

If there are a large number of speakers in the system, the amplifier may not have enough output to provide adequate power to each speaker. In this case, additional amplifiers or a more powerful amplifier may be required. The speaker wiring should also be checked to ensure that there are no wires touching (at amplifier outputs, speaker selector, or volume controls).

 

 

 

Can I use both Speaker A and Speaker B outputs in Bridged Mode?

 

 

 

This connection is not recommended. Speaker A and Speaker B are parallel outputs. A connection to both outputs in bridged mode will likely result in a load impedance that is below the minimum (8 ohms) for bridged operation.

 

 

 

What is the difference between the “Master Level” controls and the “Volume Trim” control on my amplifier?

 

 

 

The Master Level controls set the overall power output level and upper limit of the amplifier's output. The Volume Trim control allows the user to fine-tune the volume within the range set by the Master Level controls. The front Volume Trim control should be set to maximum when the Master Level controls are set. The Balance Trim should be in the center position.

 

 

 

What is the Delay Time adjustment for?

 

 

 

A delay time setting is used to allow for silence between audio tracks on a source (player) connected to Line 1. This will prevent the amplifier from reverting to the Line 2 input prematurely.

 

 

 

I don't have RCA output jacks (line level) on my old receiver. How do I connect to the AMP200/210 or AMP300/310?

 

 

 

The 200 and 300 series amplifiers are equipped with high-level inputs (labeled “Speaker In”) that accept a speaker wire connection from the speaker outputs on your receiver. If this is your only input source, set the input switch on the amplifier to Line 2.

 

 

 

There is a switch above the “Speaker In” input connectors on the amplifier. Should the switch be set to the Line 1 or Line 2 position?

 

 

 

This switch is for designating the speaker level input as the primary input (Line 2) for continuous use or the “override” input (Line 1) for occasional use.

 

 

 

 

 

 

If the speaker input connection is the only source connected to the amp, set the switch to the Line 2 position. If the primary source is connected to the Line 2 RCA inputs, set the switch to the Line 1 position for a secondary source connected to the speaker level inputs.

 

 

 

My amplifier is shutting down or going into protect mode. What is the cause?

 

 

 

There are several conditions that can cause this. One possible cause is a speaker with a shorted voice-coil. All speakers should be checked for operation.

 

 

 

 

 

 

Another possible cause is that the combined impedance of the speakers is below the minimum of the amplifier. Beyond two or three pairs of speakers, impedance-matching devices are needed (speaker selector box or impedance-matching volume controls).

 

 

 

 

 

 

It is also possible there is an internal problem with the amplifier that will require service attention to correct.

 

 

 

How do I connect my equalizer?

 

 

 

Equalizers are most commonly connected to the Tape Monitor inputs (play) and outputs (record) on a receiver or preamplifier. The “Main Out” RCA jacks on the EQ are connected to the Tape inputs on the receiver/preamp. The “Audio In” RCA jacks on the EQ are connected to the Tape outputs on the receiver/preamp. This connection will work only if the receiver/preamp allows the Tape Monitor to be activated at the same time a different input source is selected (i.e. CD player).

 

 

 

 

 

 

Alternate connections:

If the receiver provides preamp outputs and main inputs, they can be used to connect an EQ: The “Main Out” RCA jacks on the EQ are connected to the “Main In” inputs on the receiver/preamp. The “Audio In” RCA jacks on the EQ are connected to the “Preamp Out” outputs on the receiver/preamp.

 

 

 

 

 

 

If the above two methods are not feasible, then CDR inputs/outputs or VCR audio inputs/outputs on the receiver may also work. It depends on the design and functionality of the receiver you are using. Consult the owner's manual for the receiver to determine how those inputs/outputs function.
