AMPLIFIER APPLICATIONS
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.
Switch setting checklist:
-INPUT MODE: 5CH DISCRETE
-CH 1/2
-CH 3/4
Crossover frequency control checklist:
-CH 1/2 HIGH PASS: N/A
-CH 3/4 HIGH PASS: N/A
-CH 3/4 LOW PASS: N/A
-CH 5 LOW PASS: 100 Hz
Please note that these frequency points are suggestions only. Refer to the loudspeaker manufacturer specifications and the section “Setting up systems after installation for best performance”
Level control checklist:
Refer to the section “Setting up systems after installation for best performance”
Minimum final loudspeaker impedances: 2 ohm per channel
English
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
-Connect the positive terminal of channels 1&2 mono speaker to channel 1+, and its negative terminal to channel
-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
