If a source other than a B&K series preamplifier is used to control multiple amplifiers,
only the control output voltage from the source is critical. It must be within the range, as
indicated on the rear panel, 5-24 volts DC is required. The amplifier will provide each
successive amplifier with a control voltage of 12 volts DC for reliable operation. The
amplifiers control output may be used as a source of 12 VDC @ 125 mA for other user
applications as well.
If the control function is desired, each unit in the system must remain connected at all
times and the control must be enabled. To enable the control function, the CTRL
ENABLE button must be out for each controllable amplifier in the system. For more
information on the amplifiers output status under various control conditions, refer to the
following table.
