EA-AMP-70 Installation and Users Manual
INSTALLATION – SETUP AND OPTIONS
INPUT SELECTION
CAUTION:
Only change switch positions when the amplifier is turned off.Each channel is capable of delivering the sources from
a dedicated Line-In or the Global-Inputs by changing the Line-In/ Global In switch.
POWER CONNECTION
Plug the supplied power cord into the amplifier and to a polarized wall outlet or appropriate surge protector.
CAUTION:
DO NOT plug the amplifier’s power cord into a switched outlet, as is featured on some Surround Receivers. If you
wish to have the amplifier turn on when the Receiver is powered up, use the 12V trigger jack or Audio Sense mode.

BRIDGING CHANNELS
There are situations when you may wish to combine two channels into one
through a process known as bridging. The output of the two combined channels
can then be used to power one speaker.
To Bridge Two Adjacent Channels:
1. Remove Power from the amplifier.
2. Set the channel switch to BRIDGED/MONO.
3. Connect the (+) POSITIVE lead of the speaker to the (+)POSITIVE
connection of the EVEN numbered channel.
4. Connect the (-) NEGATIVE lead of the speaker to the (+) POSITIVE
connection of the ODD numbered channel.
5. Connect the output from the source to the LINE IN of the EVEN numbered
channel.
Note:
· DO NOT connect more than one speaker to the outputs of the bridged channel.
· All input selection and volume settings for bridged channels will be controlled by
the RED channel.
· Maintain an 8 ohm minimum when using bridge mode.
OPERATION
POWER SWITCH/ LED
The Power switch on the front panel of the amplifier will turn off the amplifier when the Power Mode Switch is set to ON.
BLUE – Amplifier is ON
RED – Amplifier is in STANDBY
Refer to the “Power Mode” section for further information.
ZONE LED INDICATORS
When lit, the LEDs on the front panel indicate the amplifiers operating state. Each channel has one bi-color LED, for each zone.
BLUE – Amplifier is ON and functioning properly
RED – Amplifier is ON and is not functioning properly, check for possible short at Speaker Output
OFF – (When Power LED is BLUE) A channel is not functioning and may require service.
LEVEL ADJUSTMENT
The level adjustments on the back panel of the amplifier can be used to easily adjust the level of each channel pair. One
great use for this feature is to limit the volume level in an area, such as a child’s room or guest area. 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 amplifier.
