AMPLIFIER FEATURE DESCRIPTIONS

BRUTUS BRX AMPLIFIERS:
Each model is capable of 4 & 2-Ohms stereo per channel, or 4-Ohms mono bridged operation except the
mono amps which are capable of 4, 2 and 1-Ohm loads.
Tri-Mode operation with any stereo pair of amplifier channels is possible, as with all bridgeable amplifiers.
The input sensitivities for rated output powers are variable from 0.2V to 6V for the multi channel amplifiers
and 0.2V to 9V for the mono models.
All crossovers are fully variable in their respective ranges.
Crossover filters are 12dB/Octave.
1 set for channels 1 & 2.
The X-OVER slide switch selects the internal crossover functions:
-The input signal is routed directly to the LINE OUT RCA jacks, regardless of the X-OVER setting simplifying
daisy chaining of amplifiers.
-HPF: Selects the built in HI PASS filter.
-FULL: Bypasses all crossovers for full frequency range operation.
-LPF: Selects the built in LOW PASS filter.
MODE: Selectable Stereo or MONO operation.
HPF: Variable low frequency cut off from 60Hz to 1.3kHz.
LPF: Variable high frequency cut off from 30Hz to 250Hz.
BASS EQ: 45Hz bass boost variable from 0dB to 12dB.
LEVEL: Variable LEVEL (GAIN) control from 6.0V to 0.2V.
LINE INPUT: The line input accepts unbalanced (RCA) inputs from 0.2V to 6V.
LINE OUTPUT: The line output passes through signal from the line inputs which allows you to daisy chain
multiple amplifiers from one signal.
The 4 channel amps have the same features as the 2 channel models except that there are 2 sets of
controls.
1 set for channels 1 & 2 and 1 set for channels 3 & 4.
In addition, the 4 channel models have a Mode switch which allows you to select 2 or 4 channel operation.
Switch to 2 channel if you only have 1 set of RCA's in CH 1/2 and the unit will automatically
supply signal to channels 3/4. Select 4 channel if you are providing RCA's to channels 1/2 and 3/4.
The X-OVER slide switch selects the internal crossover functions:
-The input signal is routed directly to the LINE OUT RCA jacks, regardless of the X-OVER setting simplifying
daisy chaining of amplifiers.
HI PASS: Variable low frequency cut off from 10Hz to 1.5kHz.
LOW PASS: Variable high frequency cut off from 30Hz to 150Hz.
BASS EQ: 45Hz bass boost variable from 0dB to 10dB.
LEVEL: Variable LEVEL (GAIN) control from 6.0V to 0.2V.
The 5 channel amps have the same features as the 4 channel models except that there are 3 sets of
controls.
1 set for channels 1 & 2, 1 set for channels 3 & 4 and 1 set for channel 5.
In addition, the 4 channel models have a Mode switch which allows you to select 2, 4 or 5 channel operation.
Switch to 2 channel if you only have 1 set of RCA's in CH 1/2 and the unit will automatically
supply signal to channels 2/4/5. Select 4 channel if you are providing RCA's to channels 1/2 and 3/4 and
signal will be internally routed to Ch5. Select 5 if you are supplying RCA's to each INPUT.
The X-OVER slide switch selects the internal crossover functions:
-The input signal is routed directly to the LINE OUT RCA jacks, regardless of the X-OVER setting simplifying
daisy chaining of amplifiers.
HI PASS: Variable low frequency cut off from 10Hz to 1.5kHz.
LOW PASS: Variable high frequency cut off from 30Hz to 150Hz. (CH3/4 & 5)
BASS EQ: 45Hz bass boost variable from 0dB to 10dB.
LEVEL: Variable LEVEL (GAIN) control from 6.0V to 0.2V.
REMOTE: This is a remote input jack for the remote level control on Ch5.
SUBSONIC: Crossover filter from 15Hz to 35Hz.
LOW PASS: Crossover filter from 35Hz to 250Hz.
LEVEL: Adjusts the input sensitivity from 0.2 volts to 9 volts.
BASS EQ: Adjustable bass boost from 0db to 10dB.
PHASE: The Phase Shift is fully adjustable from 0 to 180 degrees and this allows you to control time
alignment.
REMOTE: This is the input jack for the remote Level control.
BALANCED INPUT: Accepts line level balanced input from 0.4v to 18v.
LINE INPUT: The line input accepts unbalanced (RCA) inputs from 0.2V to 9V.
LINE OUTPUT: The line output passes through signal from the line inputs which allows you to daisy chain
multiple amplifiers from one signal.
-The LINE INPUT signal is routed directly to the LINE OUT RCA jacks, and not affected by the settings on the
amplifier simplifying daisy chaining of amplifiers.
The BRX2400.1D is identical to the other BRX mono amplifiers except that the BRX2400.1D is a
linkable amplifier and features a MASTER / SLAVE selection switch and IN / OUT RCA connection. This
allows for a pair of amps to link at 2-Ohms and produce 4800 watts rms.
A POWER LED indicates the powered up and turned on condition.
All Hifonics amplifiers feature a comprehensive diagnostic system, with speaker lead short circuit, and
amplifier DC faults indicated by the red "PROTECT" LED.
CAUTION: DO NOT OPERATE ANY AMPLIFIER BELOW THE INTENDED IMPEDANCE. YOU WILL
CAUSE DAMAGE TO THE AMPLIFIER THAT WILL NOT BE COVERED UNDER THE WARRANTY
PRINTED IN THE BACK OF THE MANUAL. 2 & 4 Channel amps are capable of 4 and 2-Ohms wired
stereo and 4-Ohms wired mono bridged. The mono amps are capable of 4, 2 and 1-Ohm.
