SETUP

Amplifier Positioning
The position of the amplifier has 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.

CONNECT

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 the connection and set up process.
RCA Line Level
Use high-quality low impedance RCA cables 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

12V DC Trigger
Connect the 12V trigger output of another device to the 12V trigger input of the amplifier using a high quality mono cable.

If the receiver does not have a 12V trigger output, using a 12V power supply plugged into a switched outlet on the receiver provides the same functionality. Connect the appropriate conductor to each screw terminal, observing correct polarity.

IR Port
IR Repeater Connections

Control System Connections

FINE TUNE

After making all connections and calibrating the speakers, fine tune the subwoofer as instructed below. See pages 4‒5 for more on menu functions.
NOTE: When using an AV receiver and the LFE input, set the subwoofer calibration level to the factory setting, and select LFE for CROSSOVER.

1. Ensure that the subwoofer is connected.
   During initial setup, set the POWER CONTROL to FRONT PANEL. Once calibration is complete, switch to AUDIO SENSE to enable the automatic power-saving mode. For reference, the different modes are as follows:
   FRONT PANEL: Always on. Amplifier does not turn off automatically. Turn the unit ON/OFF using the front panel power button.
   12V TRIGGER: Amplifier turns on when 12V signal is detected and off when 12V signal is absent.
   AUDIO SENSE: Audio Sense enabled. Amplifier turns on when audio signal is detected. Unit enters standby mode if no signal is detected after 15 minutes.

2. Select the desired EQ setting or set to FLAT (unmodified sound).

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.

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

Episode amplifiers are designed to function trouble-free. Most problems that occur are due to simple issues. If having trouble, check the list of simple fixes below. If the problem persists, contact Episode technical support at 866.838.5052.

No audio output| • Audio cable to the source component is not connected properly, connection to output or the cable is defective. Check connections or replace cable with one that has been verified as good.
• Amplifier is in standby mode and needs to be turned on (blue LED).
• Check the connections of the speaker wire at both the speaker and amplifier.
• The level adjustment is turned down. Slowly turn the dial to the right to raise the volume.
---|---
Hum or buzzing sound is heard| • Check RCA input cables by removing them one at a time and verify connections.
Amplifier will not turn on| • Ensure the amplifier is plugged into a live outlet.
• Ensure the power switch on the front panel is on (blue LED).
• Fuse is blown. Replace with 8AL  fuse type.
• The power mode may be set to the wrong mode for the system’s configuration or setup.
Unable to control menu| • Ensure amplifier is not in Lock Mode. Hold for 10 seconds to unlock menu.
