PAB 5400 5-Channel Amplifi er

The PAB 5400 has three sets of inputs:

Line  inputs  on  RCA  jacks  for  channel  pairs  1&2,  3&4,  and  MONO 

channel  5.  These  inputs  can  be  used  in  various  combinations,  to 

suit the application, depending on the settings of the INPUT MODE 

switch,  and  the  X-OVER  switches  for  channels  1&2,  and  channels 

3&4, respectively.

INPUT MODE slide switch:

- In the CH2 position, ALL fi ve amplifi er inputs are selected from the 

CH1/CH2 RCA jacks. Channel 5 receives a mono mixed signal.

- In the 4CH position, channel pair 1&2 receive input signal from RCA 

jacks CH1 and CH2, and channel pair 3&4 receive input signal from 

RCA jacks CH3 and CH4. A mono mixed signal from these four RCA 

jacks are also fed to channel 5.

- When 5CH DISCRETE is selected, each channel receives an input 

signal from its respective input RCA jack. Channel 5 has two jacks 

on its LINE INPUT, which are summed together.

CH1/2 X-OVER slide switch:

- FULL: Sets this pair to full range operation.

- HP: Selects the HIGH PASS fi lter, variable from 50 Hz to 4 KHz.

CH3/4 X-OVER slide switch:

- FULL: Sets this pair to full range operation.

- B.P.: In this mode, the HIGH PASS and a LOW PASS fi lter, both fully 

variable from 50 Hz to 4 KHz, are selected to form a BANDPASS 

crossover fi lter.

- HP: Selects the HIGH PASS fi lter, variable from 50 Hz to 4 KHz.

CH 5:

- The channel 5 functions were chosen to be very specifi c to mono 

bass operation, and not switchable:

- The LOW PASS fi lter has a variable range from 30 Hz to 150 Hz.

- The BASS EQ gives a bass boost, 0 to +9 dB, at 45 Hz.

- The Premium Mono Amplifi er is capable of 4, 2 & 1 Ohm loads.

- The input sensitivities for rated output powers are variable from 

0.2 volt to 9 volts.

- All crossovers are fully variable in their respective ranges.

- Crossover fi lter slopes are 24 dB/octave for mono fi lters.

- A POWER LED indicates the powered up and turned on condition.

CAUTION:

DO NOT OPERATE ANY AMPLIFIER BELOW THE INTENDED IM-

PEDANCE. YOU WILL CAUSE DAMAGE TO THE AMPLIFIER THAT 

WILL NOT BE COVERED UNDER THE WARRANTY PRINTED IN THE 

BACK OF THE MANUAL.

Mono amps: 4, 2 & 1 ohms

PAB 1200.1 D Mono Amplifi er

The 1 channel mono amplifi ers are capable of 4, 2 & 1 ohm loads and 

can be used in any of the “bi-amplifi er” systems described in the 2 

and 4 channel directions.

The line input signal is routed directly to the line output RCA’s jacks 

regardless of the crossover settings.

The  REMOTE  jack  allows  the  addition  of  the  Bass  Remote  module 

which controls the BASS EQ signal.

- SUBSONIC allows control from 10 Hz to 35Hz

- BASS EQ allows control from 0dB to 9 dB

- LOW PASS allows control from 35Hz to 250Hz

- PHASE shift allows 0 degrees to 180 degrees

- LEVEL: allows you to match the amplifi er input level (gain) to the 

Radio/CD player output level.

-  POWER:  indicates  that  the  amp  has  power,  ground  and  remote 

turn-on input via a green L.E.D.

- PROTECT: indicates that the amplifi er has detected a fault and will 

not operate. There are several possible problems that can cause the 

amplifi er  to  go  into  the  protect  mode.  See  the  trouble  shooting 

guide in the back of the manual for details.

- BALANCED INPUT: Accepts line level balanced input from 0.4v to 

18v.
