BHK Signature Preamplifier
If the front panel lights and display are not functional, check to make sure you have the unit plugged
into an AC outlet. Check to make sure the rear panel master power switch is in the UP and ON
position. Press the front panel PS Audio Logo button, located on the far left corner of the preamplifier’s
front panel.
Make sure the display DIM function has been deactivated. Press the master ON button on the remote
control.
If the unit inexplicably turns on or off, check to make sure the front panel Standby button, the PS
logo light, isn’t sticking to the sides of the front panel. Humidity, shipping, excessive movement can
sometimes pressure the logo button to stick. Pushing it in and out with small force, or wiggling it can
often free the button.
If no sound comes out of the system with the BHK Preamplifier connected, there are several areas to
check.
First check the BHK preamplifier itself. Make sure you’re on the correct input. Push the select button
to the left of the display screen. One push displays the input you’re currently on. Make certain that is
the one you wish to be playing.
Next make certain you haven’t engaged the Mute function. When engaged from the remote control,
an
M
will appear to the right of the volume level on the front panel display. Press the Mute button just
above the word Preamp on the remote control to disengage.
If you’re playing on loudspeakers, check to make sure you haven’t got a headphone or headphone
jack plugged into the BHK Preamplifier’s headphone input. The preamp’s outputs are automatically
disconnected when a headphone jack has been inserted.
If there is too much energy in one channel or the other, when you believe there should be equal
levels per channel, check to make sure you haven’t inadvertently engaged the balance control. The
balance control is located on the remote right above the word
Preamp
. Touch either the left or right
facing arrow and the display should show a 0 if the balance has not been engaged.
If the balance control has been activated, you will also see a right or left facing arrow to the side of
the level indicator’s numeric value on the BHK Preamplifier’s screen.
If, for some reason, the volume control does not respond, it may mean you are in the HT (Home
Theater) mode. Switch inputs and see if another input does respond to the volume control. When
in the HT mode, an HT will appear near the bottom of the BHK Preamplifier’s screen. You can turn
the HT feature on or off via the setup menu. Please refer to this manual’s section on setting the HT
mode.
If you experience a hum through the speakers or the headphones this can be caused by several things.
The first is the source. If there is an excessive amount of buzz or noise from the loudspeaker, it may
