BHK Signature Preamplifier
The BHK Preamplifier is designed to connect to your power amplifier. You can use either the XLR
balanced outputs or the single ended RCA outputs to connect. If you are bi-amping, it is permissible
to employ an RCA or XLR external splitter.
If you wish to use one set of outputs for the power amplifier, like the XLR connectors, and the RCA to
feed a subwoofer, (for example) this works fine.
Connecting cables of any length of 50 feet or less are acceptable, though cables longer than 10 feet
may be less problematic if they are balanced interconnects.
The quality of the connecting cable is important. Pay particular attention to the output cable pedigree
as it can have an impact on the performance qualities of the sound.
There are two trigger ports on the rear panel of the BHK Preamplifier. Each of the two trigger jacks
outputs a +12V signal to connected equipment when the BHK Preamplifier front panel standby button
is activated. The +12V signal will stop when the BHK preamplifier is in standby mode. These trigger
outputs are typically used to switch on/off compatible power amplifiers when the BHK Preamplifier is
active. The matching BHK Signature 250 or 300 power amplifier series has matching trigger inputs, as
do many other power amplifier types.
POWER UP THE UNIT
Once everything is connected, including the power cable to an appropriate AC power source, it is
time to power up the BHK Preamplifier. Switch the master power switch, located on the rear panel of
the BHK Preamplifier, to the ON position. We recommend this master power switch be left in the ON
position and AC power continue to be supplied even when the preamplifier is not in use.
Push the front panel PS Logo Standby/Operate button, located on the top left corner of the front panel
of the BHK Preamplifier.
