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.
