GENERAL DESCRIPTION

The MPS2 outboard power supply provides bipolar DC power for the various Bryston preamps and cross- overs, including the BP26 series of preamps, the BP1.5 Phono equalization stage and 10B crossovers specifi- cally designed to be used with external power supplies (10B-LR-EPS, 10B-STD-EPS & 10B-SUB-EPS) .

The MPS2’s power ON/OFF switch is a toggle switch is located on the front panel along with a green LED to indicate power ON.

REMOTE ON/OFF FUNCTIONS

When the MPS2 is turned on, any BP26 preamps, or other Bryston products connected to its 4 main out- puts, will also be turned on. Also, any other equipment connected to the MPS2’s remote trigger outputs or switched remote trigger outputs may also be turned on.

On the rear of the unit there are five 2 pin terminal blocks that provide control signals for remote on/off functions. Plug-in screw adjust terminal blocks are provided for all 5 of these connectors. These terminal blocks accept bare wires between 12 and 26 AWG. Insulated wires should be stripped to expose .3 inches (5/16” or 8mm) of bare wire. Use a small blade screw- driver (<1/8”) to open and close the wire cages. Do not overtighten; maximum torque should be 4.5 pound- inches (0.5N-m) or less.

REMOTE ACTIVATION of OTHER EQUIPMENT VIA THE MPS2

To turn on a Bryston amplifier by turning on the MPS2: 1st) Connect insulated wires from the 2 pin REMOTE TRIGGER connector on the rear panel of the MPS2

to the two IN terminals on a Bryston power amplifier remote control connector intended for a 4~14V AC/DC control signal.

2nd) Put the amplifiers “EXTERNAL TURN ON” switch in the EXTERNAL position for the amplifier to respond to remote control turn-on signals (see figure 2).

To turn a Bryston power amplifier OFF and ON when the BP26 pre-amp is MUTED and unMUTED respectively: 1st) Connect the SWITCHED TRIG OUT pins of one of the

MPS2’s 4 outputs to the two IN terminals on the power amp’s remote control connector.

2nd) Place the power amplifiers EXTERNAL TURN ON switch in the EXTERNAL position.
