Introduction

Congratulations on your purchase of an Destination Audio SWA200 subwoofer amplifier! Your subwoofer amplifier is the result of many years of research and development dedicated to producing high quality products for home audio and audio/video systems.

This manual contains features, setup recommendations and specifications for the Destination Audio SWA200 subwoofer amplifier. It is recommended you thoroughly read through the material contained in this manual before connecting your subwoofer amplifier. This will ensure you have a good understanding of how to install your speaker for optimum performance; allowing for years of listening enjoyment.

Front Panel

The following are descriptions of the front panel functions (refer to figure 1).

NOTE:

When buttons are pushed in they are in the “on” position.

1. Power Button:

This button allows the amplifier to be turned on and off manually or when kept in the “on” position and the Auto Button (see figure

1, #2) is kept in the “on” position; the amp will automatically turn on when it detects an incoming audio signal. The power indicator light above the power button will glow when the amplifier is on.

IMPORTANT! The volume control should be set at the minimum setting

(all the way counter-clockwise) before plugging the amplifier into an

A/C wall outlet.

2. Auto Button:

This button, when in the “on” position, allows the amplifier to automatically turn on when there is an incoming audio signal present at either the “Line” inputs or “From Receiver/Speaker Level” inputs. For this function to work properly, the Power Button must be left in the “on” position. The light above the Auto Button will glow when the unit is in

“standby” mode. No other lights will glow.

3. Boost:

This button, when in the “on” position, will increase output at 25Hz by

4dB. Use this button with discretion and caution as some subwoofers may not be able to handle this extra boost

.

4. Phase Control:

This knob changes the output phase of the amplifier.

Changing the phase will change the way the subwoofer(s) and main speakers interact with each other at the crossover frequency. Typically, this will be set to the 0° position. To operate, press then release the phase button. While it is extended, adjust as necessary if any problem between the subwoofer and main speakers exist. Press the button back in.

5. Crossover:

This button allows the amplifier’s internal low-pass filter to be defeated when using an external crossover, or when the crossover is not needed. When defeated (off), the subwoofer output will play the full-range of the audio signal. This button has no effect on the high level inputs and outputs shown in figure 2, #10 and #11. The high level output (figure 2,

#10) has a 100Hz high pass filter and is not adjustable or defeatable.

6. Crossover Frequency Control:

The variable crossover frequency control allows you to set the point of the low-pass frequencies being reproduced by the amplifier anywhere from 40Hz-180Hz. Try an initial setting of the crossover frequency control at the midway (12 o’clock) setting. Increasing the crossover frequency will produce more mid-bass output from the amplifier.

7. Master Volume Control:

This dial allows you to adjust the output level of the subwoofer to match the audio system. For an initial setting, turn the volume control up one quarter of a turn (9 o’clock) position). The volume control may be adjusted while listening to match the subwoofer output level with the rest of the system.

REMINDER

–The volume control should be at the minimum setting (all the way counter-clockwise) before plugging the amplifier into an A/C wall outlet.

Rear Panel

The following describes the control functions of the rear panel of the amplifier

(refer to figure 2).

8. Line/LFE Input: These RCA type terminals are for the pre-amp level input signals coming from a processor or preamplifier labeled

“subwoofer” or “LFE.”

IMPORTANT! Use either the Line Level inputs or the “Speaker Level” inputs separately. DO NOT use both, as damage to the receiver and/or the Subwoofer Amplifier may result.

WARNING! DO NOT connect an amplified or speaker-level signal into the line/LFE input(s).

9. Line/LFE Output: These RCA type terminals carry the same audio signal as the line inputs. These terminals are used if an output signal is needed elsewhere in your system. These outputs are full-range outputs.

10. Speaker Level Output:

This 100Hz high-pass speaker output is for your satellite/main speakers. The built-in crossover limits the frequencies below

100Hz from being sent to your satellite/main speakers. You may use these speaker outputs only when using the “Speaker Level” input terminals (#11).

Connect your satellite/main speakers (observing the proper polarity) to the binding posts labeled “Speaker Level Out.”

NOTE:

These connectors are not powered by the Subwoofer Amplifier.

11. Speaker Level Input: These connectors are for the amplifier or speakerlevel audio output from an amplifier or receiver.

IMPORTANT! Use either the Line inputs or the “Speaker Level” inputs separately. DO NOT use both, as damage to the receiver and/or the

Subwoofer Amplifier may result.

12. Subwoofer Output:

This is the amplified audio output of the Subwoofer

Amplifier. If the Crossover Button (#5) is in the “on” position, the audio output will be limited to the lower frequencies selected by the Frequency Control

(#6). If the Crossover Button (#5) is in the “off” position, the audio output will be full-range. An impedance load of 4-16 ohms may be connected to this output. Please follow the instructions in the connections section of this owner’s manual for proper wiring information.

13 Dimmer : This knob adjusts the brightness of the indicator lights on the front panel.

Rear Panel (continued)

14. Fuse Access:

This is the power fuse access.

WARNING! In the event the fuse must be replaced, the replacement fuse must match exactly the original fuse value. If the replacement fuse is not of the same value, damage to the Subwoofer Amplifier may result.

CAUTION! Before replacing the fuse, disconnect the power cord from the power receptacle.

15. Voltage Selector Switch:

If your model features this capability, this switch allows you to select between 110V A/C (60Hz) or 220V A/C (50Hz).

WARNING! If the voltage setting does not match the A/C power supplied, damage to the Subwoofer Amplifier may result.

16. Power Cord Receptacle: The supplied power cord needs to be connected to this receptacle in order for the Subwoofer Amplifier to work properly.

WARNING! Make certain that you are using the proper power cord and voltage selection for the type of A/C power supplied.

Troubleshooting

Situation:

No sound from the subwoofer(s)

Sound from at least one subwoofer, but not the other(s)

Probable Cause:

Amplifier is not connected to constant A/C power outlet.

Subwoofer(s) is/are not connected to the amplifier correctly

Solution:

Make certain the amplifier is plugged into an unswitchable

A/C power outlet

Make certain that subwoofer(s) is/are connected properly (refer to the connections section of this manual)

Amplifier is not receiving an audio signal for the pre-amp/receiver

Electrical short in wiring

Amplifier fuse might be blown

Bad connection(s) to nonworking subwoofer(s)

Electrical short in wiring

If one subwoofer is damaged due to being overdriven, then it may have a negative effect on another subwoofer used in a series connection.

Maker certain there is an audio signal from preamp/receiver and audio connections resemble those in the connections section of this manual.

Verify that all connections are complete and secure, with no stray wires contacting other terminals.

Replace fuse (if fuse is not readily accessible, consult your authorized Destination

Audio dealer). WARNING:

Before replacing fuses, please see the rear panel features/controls section

(Figure 2, #14) of this manual.

Verify all wires are properly connected.

Verify that all connections are complete and secure, with no stray wires contacting other terminals. If problem is in wire itself, replace the suspect wire.

Check each individual subwoofer to verify each is still operational

Troubleshooting (continued)

Situation:

Performance is less than expected

Probable Cause:

The + and – polarity of the subwoofer wire might be reversed on the subwoofer

Crossover frequency is not adjusted correctly

Crossover button is in the wrong position

Solution:

Check the entire system for proper polarity

Adjust crossover frequency by turning the Crossover

Frequency Control clockwise until desired sound is obtained

Check Crossover On/Off button for correct setting
