How to connect your system

See illustration 1 and illustration 3

Inputs

Single- ended operation:
All inputs are similar regarding sonic performance.
Unused inputs may be shorted to ground, using a RCA shorting plug.

Balanced operation:
There are three set of balanced inputs.
Two set for 6 channel operations, labelled Input 1 and Input 2, and one set for 2 channel
operations labelled CD.
Note that the two 6 channel inputs may also be used for 2 channel operations.

Outputs

REC:
Rec outputs are used for recording.
The source you listen to will be monitored through this output.
The record function is not influenced by the volume control setting.

Never use shorting plugs in outputs.

LINE OUT:
The line out is a variable output, dependent on the volume control setting and MUTE function.
These outputs controls the power amplifier(s).

SPAC:
These contacts are used to communicate with power amplifiers AW 2x120 and AW 3x120.
Connect a SPAC Com cable (sold separately) from SPAC A to one of the amplifier and SPAC B to 
the other. When these cables are connected to the amplifiers the amplifiers will automatically switch 
to mono mode when running 2 channel sources.
SPAC Multi is reserved for future use. 

DATA:
Connect an USB cable from the DATA port to a PC to upgrade the software on the EC 4.9.

REMOTE CHARGE:
Connect the remote ECT2 (sold separately) to this port to charge the remote.
