1.  Loop Outputs 1 & 2

Unbalanced mono RCA connections for sending 

audio to other equipment.

2.  Unbalanced Inputs 1&2

Unbalanced  mono  RCA  input  connections  for 

connection of sources.

3.  Balanced Inputs 1 & 2

Set-screw connections for sources with balanced 

output.

4.  Input Level Adjustment Dials

Attenuate  input  volume  levels.    Turn  counter-

clockwise to decrease and clockwise to increase 

the level.

5.  Speaker Output Connections

Set-screw  connections  for  speaker  output 

channels  1  &  2.    Accommodates  22-12AWG 

wire. 

6.  Master Power Switch

Rocker  switch  to  control  master  power  state.  

Must remain “On” during amplifier use.

7.  IEC Power Cord

Detachable power for amplifier. 

8.  Power Mode Selector Switch

Set the amplifier for control via the front power 

button (ON), 12V trigger (TRIGGER DC 12V), or 

audio sense (AUTO).

9.  12 Volt Trigger Loop In and Out

When  4.5-15  Volts  DC  are  applied  to  Loop  In, 

amplifier will turn on. When voltage is dropped, 

amplifier turns back off.  Loop out allows other 

equipment to be controlled from the same 12 volt 

signal.

10.  AC Fuse

Replaceable main power fuse.

1.  Power Switch with LED Indicator

Momentary switch for manual control of standby power mode.  Only functions when the power mode is 

set to “ON”.

BLUE

 – On.

RED

 – Standby.

2.  Protection LED

Indicates whether a channel is operating correctly or is in protection.

BLUE – Normal.

RED – Protection.  (Indicates an issue with installation or setup)

3.  Output Level Meter

Level meter flashes green to indicate current output level for each channel.  LEDs will illuminate green 

accordingly as levels ranging from -30dB to -10dB are played.  If a channel is clipping, the red CLIP LED 

will illuminate during periods of clipping (turn down input level immediately if clipping occurs).

*Terminals marked with     are hazardous live and external wiring connected to these terminals requires 

installation by an instructed person or the use of ready-made leads or cords.

1.  Input Voltage Switch

Set the input voltage for 115V or 230VAC operation based on the voltage available.

 

Note:  

The ECA-70AMP-2D includes an IEC cable meant for use with a NEMA 5-15 receptacle supplying 

115V AC power. For countries utilizing 230V AC power, the cable can be swapped to the correct 

cable for that region. When using the 230V AC input voltage setting, change the fuse in the 

amplifier from the included to a fuse rated for 230V AC. See the Specifications on page <Speci

-

fications> for the correct fuse type for each model. Using the wrong fuse could result in blown 

fuses or damage to the amplifier, which is not covered by the warranty.
