Installation
Positioning the Amplier
Episode ampliers are designed to help deliver a great audio experience that makes your music come alive for years to come. However,
where you place the amplier 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)
Minimum of 5" of free air
space above.
5"
3"
Minimum of 2” of depth behind unit
to accommodate cables and
connectors.
Minimum of 3" free air
space on each side.
3"
2"
Rack Mounting
1. Remove the amplier’s four feet from the bottom
of the chassis.
Note: DO NOT place the screws back into the
chassis. Without the feet, the length of the
screw may touch internal components and
affect the performance of the amplier.
2. Attach the included rack-mount ears to the front
sides of the amplier chassis.
3. Securely mount the amplier into an equipment
rack. The amplier will occupy 2U of rack space.
4. Even though the amplier produces very little
heat, it is always wise to leave ventilation
between components.

Cascading Ampliers
Multiple ECA-70MIXAMP-1-60 can be used in a system where more audio distribution is needed. This is achieved by using the Unbalanced
Mix Outto the additional ampliers.
1. Connect the Mix Out to the Aux 1 input of the second amplier.
2. Repeat for additional ampliers.
3. Adjust the tone of Amp 1 and then adjust the additional amps in order (Amp 1, Amp 2, and etc.).

Troubleshooting
Amp will not turn on. • Power cable to the amplier is incorrectly connected or plugged into an
outlet that does not have power. Check connections and verify power
on the outlet.
• Main Power Fuse is blown. Replace fuse and ensure power outlet is
providing the correct power and polarity for the amplier.
TEMP LED is lit. • Amplier is overheating. Install per instructions in manual, “Positioning
the Amplier”.
PROT LED is lit • Short circuit on input or output. Verify all wiring and connections.
• Too much current is being drawn on speaker output. Calculate load
attached to amp and congure so that impedance or wattage output is
within specication.
Hum or buzzing sound is heard. • Check RCA input cables by removing them one at time (powering down
the amplier before disconnecting) and checking to see if a connection
or cable is to blame.
No audio from speakers. • If output meter is active, then amplier is processing signal but output is
in protection. See section above, “PROT LED is lit.”
• If output meter is not active, then the amplier is not receiving audible
signal. Verify correct source operation ad input wiring. Turn Input or
Master volume up to an audible level.
• Amplier is in temperature protection. See section above, “TEMP LED
is lit.”
No sound from microphone input • Set the phantom power switch to the correct mode for microphone.
Verify wiring conguration and power requirements with microphone
manufacturer.
Note: If any of the troubleshooting methods listed above do not resolve the issue, please contact our Technical Support department.
