§ Connect the wires from your speakers to the appropriate outputs on the amplifier. It
is absolutely essential that you observe correct polarity in these connections.
Example: If you connect your left front output of your preamplifier to channel 4 input on the amplifier,
remember to connect your left front speaker wires to channel 4's outputs. Always observe polarity when
connecting speakers, connect amplifiers (+) to the speakers (+) and amplifiers (-) to speakers (-).
§ Double check all connections.
§ Connect a playback unit (CD, VLD, Tuner, etc...) to the preamplifier. Turn the
volume on the preamplifier to minimum. Turn on the preamplifier, then the
amplifier (in that order). Set the source on the preamplifier to the playback unit
you’ve just connected. Turn the volume up slowly and listen for music from all
channels. If this is not the case, double check your installation.
§ Should you encounter any problems that cannot be traced to the source or the
material being played, consult the “TROUBLESHOOTING” section on page 10.
Note: When turning equipment ‘off’, the amplifier should always be turned off first, then
the preamplifier. When turning equipment ‘on’, the preamplifier should always be turned
on first, then the amplifier. Before turning anything on, insure the preamplifier is at a low
volume level.
Control muting
A control is provided on each Reference 7250/7260 series II amplifier to allow remote
switching of mute on/off. The preamplifier’s control output, such as is provided with B&K
series preamplifiers, can be utilized to provide a control signal to the Reference
7250/7260 series II. If more than one amplifier is being controlled, the control signal can
be extended to include each successive unit by simply running a 1/8" MINI - JACK cable
from the CTRL OUT connector of the first amplifier to the CTRL IN connector of the next
unit (commonly referred to as ‘daisy chaining’). An example of how to connect two
amplifiers is illustrated in figure E.
