Set Up Guide


AMPLIFIER POSITIONING

Placing the amplifier can have a large impact on performance and longevity. Please take the following guidelines into consideration:
• Ensure that the unit is in a well-ventilated area that provides adequate cooling.
• A minimum of 5” should be allowed above and below the amplifier for optimum performance.

INSTALLATION

• Attach ears to the amplifier if mounting into rack.
• Bottom feet on the amplifier chassis may be removed if necessary.

CONNECTION

! CAUTION: All connections and switching must be done with the amplifier turned off. Connect the power cord last to ensure that the amplifier is off during all the connections and set up.

RCA Line Level
Use high-quality RCA cables that feature low impedance with adequate shielding and high-quality connectors.

Speaker Outputs
Use 14 or 16 gauge stranded two-conductor speaker wire. Connect the appropriate conductor to each screw terminal, observing correct polarity.

! CAUTION: When two subwoofers are connected in parallel, the nominal impedance of each subwoofer should not be less than 8Ω.

SINGLE SUB CONNECTIONS

DUAL SUB CONNECTIONS

Connect the appropriate conductor to each screw terminal, observing correct polarity.

12V DC TRIGGER

Connect the 12V trigger output of another device to the 12V trigger input of the amplifier using a high quality 3.5mm (1/8”) mono cable.

Fine Tuning


After making all connections and calibrating the speakers, fine tune the subwoofer as instructed below.

NOTE: When using an AV receiver and the LFE input, set the subwoofer calibration level to the factory setting.

1. Ensure that the subwoofer is plugged in. During initial setup, set the ‘POWER MODES’ switch to the ‘ON’ position. Once calibration is complete, switch to ‘AUTO’ to enable the automatic power-saving mode. For reference, the different modes are as follows:

TRIGGER: Amplifier turns on when 12V signal is detected and off when 12V signal is absent.

AUTO: Auto sense enabled. Amplifier turns on when audio signal is detected. Unit enters standby mode if no signal is sensed after 15 minutes.

ON: Always on. Amplifier does not turn off automatically. Unit turns on/off using the front panel power button.

2. Set the controls to positions that will enable tuning for maximum performance.

VOLUME set to 50%, or 12 o’clock

CROSSOVER set to 175 Hz, or 12 o’clock – OR – set to ‘LFE’ if LFE input is used

PHASE set to 0º

3. Play a movie scene or music track and set the system volume to an average level. Listen to the bass level from the preferred listening position. Adjust the ‘VOLUME’ control as desired.

4. If deeper bass is desired, adjust the ‘CROSSOVER’ control toward the lower frequencies. Experiment with different frequency settings until finding one that sounds best.

NOTE: When using the LFE input, set to LFE and make any crossover adjustments in the preamplifier or receiver crossover settings.

5. Continue listening to music and movie sources using the settings chosen for volume and crossover.

6. Experiment with the phase to find the best setting. Depending on the subwoofer’s placement, the bass may sound louder or deeper when the phase has been optimized. In some cases, adjusting phase will not make a noticeable difference.

NOTE: If deeper bass is desired, adjust the CROSSOVER control toward the lower frequencies. Experiment with different frequency settings until finding one that sounds best. When using the LFE input, set to LFE and make any crossover adjustments in the preamplifier or receiver crossover settings.

7. Play a movie scene or music track and set the system volume to an average level. Listen to the bass level from the preferred listening position. Adjust the VOLUME control as desired.

8. Continue listening to music and movie sources using the settings chosen for volume and crossover.

9. Experiment with the PHASE until finding the best setting. Depending on the subwoofer placement, the bass may sound louder or deeper when the phase has been optimized. In some cases, adjusting phase will make no discernible difference.

Troubleshooting


If you have a problem, try isolating it first. For example, if you’re playing a DVD and there is no sound, try replacing the DVD with an MP3 player to see if you get sound. If it does work, then the problem is with the television, DVD player, or the cables connecting them. If it doesn’t work, the problem will be with the amplifier, speakers, or those cables.

Common Solutions

PROBLEMPOSSIBLE CAUSES
NO SOUND The volume may be turned down or muted. Check the volume settings volume may be turned down or muted. Check the volume settings on both the amplifier and the DVD player/ television/ computer/ etc.
NO SOUNDMake sure the proper source is selected on the amplifier or receiver.
NO SOUNDCheck the cord connecting the amplifier with the source. The cord may be damaged or plugged into the wrong input or output.
NO SOUNDCheck the wires connecting the amplifier with the speakers. Make sure they’re connected properly and not damaged in any way.
POOR SOUND QUALITYIf you hear something like static, or the sound is cutting in and out, check the audio cables. If the problem increases when a cable is being moved, then the cable is most likely faulty or not connected properly.
POOR SOUND QUALITYToday’s audio systems may have several places to adjust the volume, for example your MP3 player may have a volume control, and your amplifier may also have one. Check to be certain that the volume isn’t turned up past 80% on any device.
POOR SOUND QUALITYTry changing sources to be certain that the selection you’ve chosen is a good quality recording.
NO POWEREnsure the amplifier is plugged into a live outlet.
NO POWEREnsure the power switch on the front panel is on (blue LED).
NO POWERFuse is blown. Replace with T5AL fuse type.
NO POWERThe power mode may be set to the wrong mode for the system’s configuration or setup.
UNABLE TO CONTROL MENUEnsure amplifier is not in Lock Mode. Hold for 10 seconds to unlock menu.
