OUTPUT CONNECTIONS
House Output:
The main or house output of the Model 1620LE is available on the Rear panel in Balanced and Unbalanced form.
Balanced Output, via XLRs, is transformer isolated and floating. Balanced or symmetrical lines should be connected as follows:
XLR
Screen
1
Hot +ve
2
Cold -ve
3
Unbalanced Output is via Phono sockets. Unbalanced lines should be connected as follows:
PHONO
Screen
Case
Hot
Center Pin
If there is a long cable run from the output of the Model 1620LE to the input of the power amplifier, equalizer, crossover network or other
connected device, we recommend connecting a 620 ohm 1/2 watt resistor across the line at the end of the cable which is hooked up to
the input of that device. This will establish the impedance of the line at approximately 600 Ohms and will make the line less susceptible
to induced noise.
Booth Output:
The booth output is the same program signal as the house output, but it is fed by a separate front panel level control for those
installations which have monitor speakers in the control booth. Connection is made on the rear panel via Male XLR-type connectors and
RCA-type phono jacks. The XLR outputs are balanced , and the phono outputs are unbalanced. The connection details are tha same
as for the House outputs.
