EA-AMP-12D-45A Installation Manual
Welcome to Episode
Episode® is one of the most highly-regarded brands of audio products available today. We appreciate your
business, and we stand committed to providing our customers with the highest degree of quality and service in the
industry.
Episode ampliers are built on the latest digital technology and deliver efcient, 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.
1. 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 effected 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. 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 to
be perfectly matched to its area. It can also be used to provide a limit on how loud each speaker may be allowed to
play.
Installation-Friendly Connections
Each pair of speakers features a removable speaker wire connector that accommodates 14-18 gauge stranded
speaker wire. The power cord is removable as well, facilitating fast and simple installations. The Global Inputs,
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.
Power Mode
Power state can be toggled using the front Power Button, 12V input, or Audio Sensing for easy automated or
manual control.
Note: The front panel power button is inoperative when the 12V Trigger or Audio Sense power modes are
selected.

3. Recommended For Installation
3.1. Tools
• #2 Philips Screwdriver
• Wire Strippers
3.2. Materials
• Speaker Wire
Use high-quality, 2 or 4 conductor, 14-18 gauge (AWG) speaker wire. The higher the strand count, the
better the sound quality will be. Using 4 conductor cables for stereo zones can save money and time on the
installation by reducing the number of wires that must be pulled.
• Source Input Cables
Source inputs on the EA-AMP-12D-45A utilize RCA connections. Use high-quality pre- or eld-terminated RCA
cables.
• Speaker Selectors and Volume Controls
For multi-room audio applications, there may be volume controls or zone selectors between the amplier
speaker output and the speakers. Make sure that any equipment used is capable of handling the wattage
supplied by the amplier.
Any equipment used to add more speakers must have built–in impedance matching, or the speaker wiring must
be congured to provide the correct impedance at the amplier.
3.3. Speaker Recommendation
The EA-AMP-12D-45A is capable of handling a 4 ohm load at 45 watts for normal outputs, or an 8 ohm load at 90
watts for bridged outputs. Use speakers rated for 4-8 ohms and capable handling at least 45 watts RMS for the
best performance.
Avoid attaching more than two 8 ohm speakers or one 4-6 ohm speaker directly to any single output zone in
Normal mode. Attach only 8 ohm speakers directly to bridged output zones. When attaching multiple speakers
to an output, use an impedance matching volume control or selector between the amplier and the speakers if
necessary to maintain the correct impedance.
