PAB 5400 5-Channel Amplifier

5 channel discrete,

one being mono low pass

You can use this configuration simply as 4 discrete full range chan- nels, with a 5th low pass channel. All of the crossovers are bypassed, except the LOW PASS on channel 5. The 5 channels can also be uti- lized with an outboard active crossover, or with crossovers in head units or equalizers.

Interconnect cable checklist:

Connect channel 1&2 inputs to the front output, channels 3&4 to the rear output, and channel 5 to the mono subwoofer output of a head unit or in dash equalizer. The LOW PASS filter on channel 5 will be in tandem with that of the source. You can either set it to the same frequency for a steeper rolloff, or set it to a higher frequency to mi- nimize it’s effect. By the same reasoning, you could switch channels 1,2,3&4 high pass crossovers in for steeper high pass slopes.

3 or 4 channel discrete, one being mono low pass

We will use the same basic setup as above to illustrate a 3 channel arrangement, by mono bridging the stereo channel pairs 1&2, 3&4. For a 4 channel setup, mono bridge only one set.

Interconnect cable checklist:

-Use 2 Y-adapters RCA cables, one for channels 1&2, and the second for channels 3&4, to create 2 inputs for channels 1,2,3&4 only, as shown.

-Connect the positive terminal of channels 1&2 mono speaker to channel 1+, and its negative terminal to channel 2-. Connect the positive terminal of channels 3&4 mono speaker to channel 3+, and its negative terminal to channel 4-.

-Channel 5 is a true single channel, and as such is not bridgeable.

Minimum final loudspeaker impedances:

-2 ohm per channel in stereo mode

-4 ohm per mono bridged pair

-2 ohm on channel 5
