Important Safety Instructions

WARNING:

To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture.

1. Read and follow all instructions and warnings in this manual. Keep for future reference.

2. Do not use this apparatus near water.

3. Clean only with a dry cloth.

4. Do not block any ventilation openings. Install according to manufacturer’s instructions.

5. Do not install near any heat sources such as radiators, heat registers, stoves or other apparatus (including amplifiers) that produce heat.

6. Do not override the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades - one wider than the other.

A grounding type plug has two blades and a third grounding prong. The wide blade or the third prong is provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.

Installation

Positioning the Amplifier

Episode amplifiers are designed to help deliver a great audio experience that makes your music come alive for years to come. However, where you place the amplifier 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 flow (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)

Rack Mounting

1. Remove the amplifier’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 amplifier.

2. Attach the included rack-mount ears to the front sides of the amplifier chassis.

3. Securely mount the amplifier into an equipment rack. The amplifier will occupy 2U of rack space.

4. Even though the amplifier produces very little heat, it is always wise to leave ventilation between components.

ECA-70MIXAMP-1-240 Installation Manual

Advanced Connections

External Audio Processing

The ECA-70MIXAMP-1-240 allows for external audio processing to equalize the output to suit the installed environment. This is achieved by using the unbalanced Pre Out and Amp In connections.

Note: This connection is effected by Master Volume, Bass and Treble Controls, keep this in mind when calibrating the external processor.

1. Remove the jumper between the Pre Out and Amp In Connections

2. Connect the Pre Out to the input of the external processor

3. Connect the output of the external processor to the Amp In connection.

4. Adjust the master volume to the 12 o’ clock position; this will provide an output level in the middle of the volume range.

5. Calibrate the external processor following the instructions provided with that device.

ECA-70MIXAMP-1-240 Installation Manual

Cascading Amplifiers

Multiple ECA-70MIXAMP-1-240 can be used in a system where more audio distribution is needed. This is achieved by using the unbalanced Rec

Line Out to send the signal from Amp1 to the additional amplifiers.

Note: The Rec Line Out is effected by Bass and Treble controls; adjust the tone of Amp1 first and then adjust the tone of the additional amplifiers.

1. Connect the Rec Line Out of Amp1 to a Source on Amp2.

2. Set the gain for the source used to Max, allowing for the volume from Amp1 mics/sources to be at the highest level.

3. Repeat for additional amplifiers.

4. Adjust the tone of Amp1 and then adjust the additional amps in order (Amp1, Amp2, and etc.).

Troubleshooting

Amp will not turn on.

POWER LED is red

Hum or buzzing sound is heard.

No audio from speakers.

No sound from microphone input

• Power cable to the amplifier 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 amplifier

• Amplifier is in Protection mode. Short circuit on input or output or too much current being drawn on speaker output. Verify all wiring and connections.

• Calculate load attached to amp and configure so that impedance or wattage output is within specification.

• Amplifier is overheating. Unplug amp and let cool. Install per instructions in manual, “Positioning the Amplifier”.

• Check RCA input cables by removing them one at time (powering down the amplifier before disconnecting) and checking to see if a connection or cable is to blame.

• Verify speakers and wiring connections. Bypass volume controls and test output with one speaker on known good wire run.

Be sure that amp jumper is in place between “Pre-Out” and “Amp In” ports.

• Verify correct source operation and input wiring. Turn volume in source up to an audible level. Turn Input or Master volume up to an audible level.

• Is Power LED red? If so, see section above, “POWER LED is RED”.

• Set the phantom power switch to the correct mode for microphone.

Verify with microphone manufacturer.
