Setup (Mono “block” mode)
Two
units, are hereby required for a
stereo
setup; one designated for the
“left”
channel; the other for the
“right”
channel.
Speaker connections
Make sure the unit is switched OFF.
Check the switch on back panel is in MONO position.
Connect the left hand speaker wires to the LEFT SPEAKER OUTPUT binding posts of the
left hand M1 PWR
unit
.
Observe polarity of the cables and connections:
Connect the + wire to red, the – wire to black. Ensure the same connection order is used at the
speaker
end of
the cable. Check there are not stray strands of speaker wire and/or plugs that are causing short circuit by
touching.
Connect the right hand speaker wires to the LEFT SPEAKER OUTPUT binding posts of the
right hand M1 PWR
unit
.
Observe polarity of the cables and connections:
Connect the + wire to red, the – wire to black. Ensure the same connection order is used at the
speaker
end of
the cable. Check there are not stray strands of speaker wire and/or plugs that are causing short circuit by
touching.
Input Connections
Connect preamp outputs to LEFT inputs only on each unit.
Please note only the LEFT input is active, the RIGHT input is inoperative in MONO mode.
Example:
Connect preamplifier LEFT output to LEFT input on
left hand M1 PWR unit
.
Connect preamplifier RIGHT output to LEFT input on
right hand M1 PWR unit.
Switches set to MONO.

Mono (block) mode audio leads connection diagram.
(Trigger and mains leads omitted for clarity).
Note: When unit is switched to MONO mode the LEFT and RIGHT RED speaker terminals are internally
connected together. Similarly, the LEFT and RIGHT BLACK speaker terminals are also internally connected
together. Thus the power from the two internal amplifiers is combined to form a more powerful monoblock.
Only the LEFT input, however, accepts the signals, RIGHT input is inoperative in MONO mode.
The diagram above shows the speakers connected to the LEFT hand outputs. It is also perfectly acceptable to
use the RIGHT SPEAKER outputs as in
mono
mode
they are exactly the same connection internally
.
