Shipping Box and Packing Material
Please keep the original shipping box and all
packing material. This will ensure the BP2-MM is
protected in future transport. In the unlikely event
you have a problem and must return it for service,
you must use the proper packing material. Ship the
unit only in the original packing material, as the unit
is not insurable by carriers otherwise. Replacement
packing materials consisting of a shipping carton
with plastic foam inserts is available from Bryston
for a small fee.
Installation and Usage
Placement
The BP2-MM is a cool-running gain stage and
can be placed in the position most convenient to
your circumstance. The nature of the product is
to amplify very low level signals, so some care in
placement is worth while to maximize performance.
Do not place the unit next to electronics known to
radiate a high amount of noise. When possible, do
not stack on top of Bryston power supply.
Connecting to Power Supply
The BP2-MM must be used with a Bryston power
supply model PS-3 or MPS-2. Only the XLR-6
terminated interconnect included with the BP2-MM
should be used to connect the BP2-MM to the power
supply. Insert the female end of the cable into the
BP2-MM and the male end to the approved power
supply. A secure connection is established when
you hear the cable click into place.
Connecting to Audio System
The input of the BP2-MM accepts a left/right pair of
RCA cables from your turntable’s cartridge output.
If your turntable has a ground screw, connect a wire
from this to the ground screw of the BP2-MM to
eliminate humming due to ground loops.
Output from the BP2-MM can then be sent to a line-
