SPEAKER CONNECTIONS

Use 14 or 16 gauge stranded two-conductor speaker wire. Connect the appropriate conductor 
to each screw terminal, observing correct polarity.

CONTROL CONNECTIONS

IR

Connect a control system to this input via a mono connector (Signal and GND only, no 12V 
signal supplied) to control the amplifier via IR from your control system. See page 6 for IR 
port location.

Ground

RS-232

Connect using the correct pin configuration for the control system in use. Configuration for 
control system serial ports can vary. Refer to the documentation for the system in use to 
ensure proper connection and configuration.
TheESA-70V2CH-IP receives control data on pin 2 (RxD – Data Receive) and transmits control 
data on pin 3 (TxD-Data Transmit). See the diagram below for details.

IP

1. 

Connect a Cat5e/6 network cable from the Ethernet port of the amplifier to a network 
with DHCP enabled (DHCP server is usually in the router).

2. 

Use an IP scanner to detect the IP address assigned to the amplifier.

3. 

Enter the IP address into a web browser to access the user interface and change 
settings.
