7. Do not block any ventilation openings. Install according to manufacturer’s instructions.
8. Do not install near any heat sources such as radiators, heat registers, stoves or other apparatus
(including ampliers) that produce heat.
9. Do not override the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades -

FEATURES
DURABLE AUDIOPHILE DESIGN
These Episode Ampliers use the latest digital technology to deliver cool-running performance from a compact, reliable package.
Plus, they feature superior quality components for outstanding sound quality and are up to 90% more efcient than conventional
analog designs.
MULTIPLE STAGES OF PROTECTION
Each pair of channels (or Zone) is individually protected with an operation mode indicated by bi-color LEDs on the front of the
amplier. These enable simple troubleshooting. If the circuitry determines that a channel must be shut down for protection due
to a short, only the channels that are affected will be turned off. The other zones will continue to play.
GLOBAL A & B AND DIRECT INPUTS
A dedicated input can be assigned to a pair of channels via the channel Line In connection. Each pair of channels can also
be congured to play common signals from the global input. When using the global connections, odd-numbered channels will
receive the right channel, and the even-numbered channels will receive the left channel. This is further indicated by the color of
the channel Line In jacks (odd numbers have white jacks and even numbers have red jacks). A 3 position switch is available for
each channel pair to choose between the line-in and the 2 Global-Inputs. This provides unparalleled exibility that is needed for
today’s demanding custom audio installations.
INDIVIDUAL CHANNEL AND GAIN ADJUSTMENTS
Each pair of channels has its own level adjustment which adjusts the maximum output. This allows the output of to be perfectly
matched to its area. It can also serve to provide a limit on how loud each speaker may be allowed to play. Be sure 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 amplier.
INSTALLATION-FRIENDLY CONNECTIONS
Each pair of speakers feature a removable speaker wire connector that accommodates up to 14 gauge stranded speaker wire.
The power cord is removable as well, facilitating fast and simple installations. The Global Inputs, Loop Output, and individual
Channel Inputs are all high-quality RCA connectors.
BRIDGING
The power output of adjacent 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 amplier includes an accessory package of rack ‘ears’ that may be attached to the amplier. The amplier feet
can be easily removed for clean rack mounting. The amplier chassis and rack ears are NOT designed to support anything other
than the amplier. DO NOT stack components on top of the amplier, as it could damage the amplier’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 amplier. 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.

Sets the ampliers power mode:
On – Turns ON / OFF via front power button
12V – Turns on when +12V is received at Trigger input
AUDIO - Turns on when a minimal amount of audio signal is received at the audio
inputs and will go into standby after 18 minutes of no audio signal.
Note: The front panel power button is inoperative when the 12V Trigger or Audio Sense power
modes are selected.
10. 12V TRIGGER IN/OUT

signal is regenerated to the 12v out for triggering additional ampliers.
Note: the front panel power button is inoperative when the 12v trigger or audio sense power
modes are selected.
