stand committed to providing our customers with the highest degree of quality and service in the industry
Episode® Ampliers are built on the latest digital technology and deliver efcient, clean power to every room. Each model is
designed to produce the subtle details of music, while having the exibility to meet a variety of installations. For the best sound
quality, use Episode® Speakers to complete the system.
FEATURES
DURABLE AUDIOPHILE DESIGN
This Episode Amplier utilizes the latest digital technology to deliver cool-running performance from a compact, reliable package.
Plus, it features superior quality components for outstanding sound quality and is up to 90% more efcient than conventional
analog designs.
MULTIPLE STAGES OF PROTECTION
Each channel is individually protected with an operation mode indicated by a bi-color LED on the front of the amplier. This
enables simple troubleshooting. If the circuitry determines that a channel must be shut down for protection due to a short, only
the channel that is affected will be turned off. The LED for the channel with trouble will turn red. The other channel will continue
to play and maintain a blue status LED. Once conditions return to normal for the channel with trouble, the status LED color will
return to blue.
LEVEL GAIN ADJUSTMENTS
The amplier has a global level which adjusts the maximum output to both channels. It can also serve to provide a limit on how
loud the speakers may be allowed to play.
INSTALLATION-FRIENDLY CONNECTIONS
Each speaker channel features a ve-way binding post that accommodates multiple 12-18 gauge stranded speaker wires. The
power cord is removable as well, facilitating fast and simple installations. The Channel Inputs are high-quality RCA connectors.
BRIDGING
The power output of the two channels can be combined to provide extra power when needed in certain areas. This is easily
accomplished by ipping a single switch. Maintain an 8 ohm minimum when using bridge mode.
RACK-MOUNTABLE
Each Episode amplier includes an accessory package of rack ‘ears’ that may be attached to the amplier. The amplier feet
can be easily removed for clean rack mounting. The amplier chassis and rack ears are NOT designed to support anything other
than the amplier. DO NOT stack components on top of the amplier, as it could damage the amplier’s chassis.
POWER MODE
Power state can be toggled using the front Power Button, 12V input, or Audio Sensing. The method for power toggle is set by
using the Power Mode Switch on the rear of the amplier. See Power Mode Switch under Rear Channel Features for information
on the operation of each mode.
Note: The front panel power button is inoperative when the 12V Trigger or Audio Sense power modes are selected.

POSITIONING YOUR EPISODE AMPLIFIER
Episode ampliers are designed to help deliver a great audio experience that makes your music come alive for years to come.
However, where you place the amplier can have a large effect on the performance that you receive and the life of the unit.
· Be sure that the unit is in a well-ventilated area that provides adequate cooling.
· Do not block the cooling vents located on both sides of the unit.
· Do not place the unit on carpeting or any similar material.
· Do not install the unit near a source of heat, or in an extremely humid or wet location.
· If your installation lacks good air ow (such as solid cabinet doors or wall-mounted racks), it may be necessary to create
ventilation to allow outside air into the space.
· Allow a minimum of 5” of free air space above the unit.
· Allow a minimum of 3” of free air space on either side of the unit. (Does not apply to rack mounting)
VENTILATION
Do not block ventilation holes, or impede air ow by placing objects on or around the amplier. Do not place the amplier on
carpeting or any similar material. Do not install the amplier near a source of heat, or in an extremely humid or wet location.
INSTALLATION – GETTING CONNECTED
CAUTION: All connections and switching must be done with the amplier’s power switch positioned to ‘Off’. Connect the power
cord last to ensure that the amplier is off during all of your connections and set up.
INPUTS
For line level connections, use high-quality RCA cables that feature low impedance, shielding and high-quality connectors.
SPEAKER OUTPUTS
Use 12-18 gauge stranded two-conductor loudspeaker wire for all high level connections. At each loudspeaker-level connection,
ensure that at least 2 inches of each conductor are separated. Strip away 1/4 inch of insulation from each conductor. Connect the
appropriate conductor to each binding post, observing correct polarity.

VERIFYING PHASE
When proper polarity is not maintained, the speakers play at the opposite ‘time’ from each other, this is known as out of phase.
The result is audio with lack of bass and vocals that sound thin or distant.
If during or after calibrating your receiver you suspect the sound is not right and you cannot see any markings on the wire to
verify polarity is correct, try this simple test:
1. Sit in the normal listening position for the system.
2. Play some music with your receiver set to Mono.
Listen to the music and observe the audio.
- Does the bass sound full and even with the other audio?
- Do the vocals sound centered and even in volume?
If any of the answers are YES, follow steps 3 and 4.
3. Turn off your receiver and reverse the connections for one of the speakers.
4. Repeat your test at the same volume level. When the sound has the loudest and best sounding bass, and vocals are centered
and clear, your connections are correct and in-phase.
LOOP OUTPUT
Any source connected to the Line In Input can be sent to other components or ampliers by connecting them to the Loop output
connector.

INSTALLATION – SETUP AND OPTIONS
POWER CONNECTION
Plug the supplied power cord into the amplier and to a polarized wall outlet or appropriate surge protector.
CAUTION: DO NOT plug the amplier’s power cord into a switched outlet, as is featured on some Surround Receivers. If you
wish to have the amplier turn on when the Receiver is powered up, use the 12V trigger jack or Audio Sense mode.
BRIDGING CHANNELS
There are situations when you may wish to combine two channels into one, or “bridging”. The output of the two combined channels
can then be used to power one speaker.
To Bridge Two Adjacent Channels:
1. Remove Power from the amplier.
2. Set the channel switch to BRIDGED/MONO.
3. Connect the (+) POSITIVE (RED) lead of the speaker to the (+)POSITIVE (RED) connection of the EVEN numbered channel.
4. Connect the (-) NEGATIVE (BLACK) lead of the speaker to the (+) POSITIVE (RED) connection of the ODD numbered channel.
5. Connect the output from the source to the LINE IN of the EVEN numbered channel.
Note:
• DO NOT connect more than one speaker to the outputs of the bridged channel.
• All input selection and volume settings for bridged channels will be controlled by the RED channel.
• Maintain an 8 ohm minimum when using bridge mode.
OPERATION
POWER SWITCH/ LED
The Power switch on the front panel of the amplier will turn off the amplier when the Power Mode Switch is set to ON.
BLUE – Amplier is ON
RED – Amplier is in STANDBY
Refer to the “Power Mode” section for further information.
ZONE LED INDICATORS
When lit, the LEDs on the front panel indicate the ampliers operating state. Each channel has one bi-color LED, for each zone.
BLUE – Amplier is ON and functioning properly
RED – Amplier is ON and is not functioning properly, check for possible short at Speaker Output
OFF – (When Power LED is BLUE) a channel is not functioning and may require service
LEVEL ADJUSTMENT
The level adjustment on the back panel of the amplier can be used to easily adjust the level of the amplier.
One great use for this feature is to limit the volume level. Be sure to set the volume at a level that does not clip or cause distortion
when the volume is at the maximum level. This can cause damage to the speakers and the amplier.
