You can switch your
When you switch the LOOP 1/2 > 3/4 Switch for channels 3 and 4 to its ON position, these channels receive the internally paralleled looped input signals from the same cables connected to the inputs of channels 1 and 2. Input 1 loops over to channel 3. Input 2 loops over to channel 4.
The Loop 1/2 > 5/6 Switch for Channels 5 and 6 offers the same internal paralleling convenience. Input 1 loops over to Channel 5. Input 2 loops over to Channel 6.

The
Polarity
It is important to observe correct speaker connection polarity to prevent phase cancellation. One side of the speaker wire will have some sort of mark, either printing, a raised ridge on the insulation or a different color of conductor. This permits you to know which wire you had connected to the + and which to the — speaker terminals so you can do exactly the same at the power amplifier terminals. Polarity is marked separately for both stereo and bridged connections.
Banana Plugs
Banana plugs offer the most convenient connection to the speaker terminals. They also have a large amount of surface contact into the speaker terminal. For these reasons, we recommend the use of banana plugs in most applications. However, you may want to use the “gas tight” connection provided by spade lugs or bare wire.
Spade Lugs
If you prefer to use speaker cable with spade lugs, make sure you do not permit the lug to rotate as the terminal is tightened. Do not overtighten the speaker terminal onto the spade lug. The limited warranty does not cover terminals that are sheared off as a result of overtightening.
Bare Wire
If you use bare wire without plugs, be sure to strip off only enough insulation so the bared wire fits into the hole that runs sideways through the terminal’s metal shaft. Before inserting the wire, twist all its strands tightly to prevent strays that could cause a short circuit between + and — terminals or adjacent channel terminals. If you have a soldering iron, it is a good idea to “tin” the bare wire with solder to keep it from unraveling and to prevent oxidation.
