CX242: I NSTALLATION AND OPERATION MANUAL 10
With no external connection to pin 3, an internal 15k resistor connected to the +15V
power will ‘pull up’ the source select control voltage and the ‘off’ position will be selected.
The output impedance of the control voltage source should be low enough to overcome
the influence of this resistor. If you require to fix the music signal to the Line 1 input, wire
a 20k resistor between pins 1 & 3 on the remote control connector.
If the control voltages are not isolated, there is a small risk of creating a ‘ground loop’ by
linking the CX242 ground with the ground of the equipment providing the control voltages;
we suggest that all pieces of equipment be positioned in close proximity.
