MONO CONNECTION - with Mono Switch option
For 200+ watt mono operation:
1) Set the MONO SWITCH to “Mono”.
2) Ensure that the two BALANCE/SE switches are set identically to one another.
3) Connect the input cable to either XLR connector (balanced source) or to either RCA
connector (unbalanced source).
4) Connect the negative speaker lead to either “COMMON” binding post.
5) Connect the positive speaker lead to the “4-8" binding post associated with the Common
post selected in step 4. In mono operation, this will match well with speakers ranging from
approximately 2 to 8 ohms.
6) Do not use the “1-2" or “2-4" binding posts.
MONO CONNECTION - without Mono Switch option (early production units)
For 200+ watt mono operation:
1) Connect identical input signals to the two input jacks. It is possible to use a “Y” adapter to
do this, or with two cables if your preamplifer has two pairs of outputs.
2) Connect a jumper wire between the two binding posts labeled “COMMON”.
3) Take note of your loudspeaker’s impedance. If it is 4 or 8 ohms, connect a jumper between
the two binding posts labeled “8 OHMS”; if it is 2 ohms, connect a jumper bewteen the two
binding posts labeled “4 OHMS”.
4) If your speaker is 4 or 8 ohms, connect it to the COMMON and 8 OHM binding posts of
either channel; if your speaker is 2 ohms, connect it to the COMMON and 4 OHM binding
posts of either channel.
5) Ensure that the BALANCE/SINGLE-ENDED switches are set identically.
