INPUT and INPUT LINK
The E-PAC signal input connector is a 3 pin female XLR. Below and
wired in parallel is a 3 pin male XLR input link connector used to
feed the input signal on to the next device in the system signal
chain.
MIX IN
A 3 pin female XLR connector provides a MIX IN input. A second
signal fed to this input is summed to the main INPUT. If Left and
Right components of a stereo source are fed to the main INPUT
and MIX IN connections then a mono sum signal is derived from
the speaker output. Please note that the resultant output is 3 dB
higher.
The output on the INPUT LINK connector is derived from the signal
fed to the INPUT connector. An additional signal fed to the MIX IN
connector will not appear at the INPUT LINK output.
SPEAKER OUT
The E-PAC is fitted with a single Speakon-NL4 speaker output
connector. With configuration settings which transmit full-range
signal (e.g. E3 or LINEAR) all four pins on the Speakon connector
are driven, pins 1+ and 2+ carry positive signal, 1– and 2– carry
negative signal. With SUB configurations selected pin 1+ is
disconnected automatically. This prevents mid-high cabinets from
accidental damage by subwoofer signal.
REMOTE
The E-PAC is fitted with a two-wire serial remote control interface.
The 3 pin female DIN remote control connector is located beneath
the speaker output. The connector is opto-coupled.
The remote functions are detailed in section 2.5. (Remote control
and monitoring).
