BRZ1200.1D / BRZ1700.1D MONO AMPLIFIERS
BRZ2100.1D / BRZ2400.1D MONO AMPLIFIERS
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 HFR-3 module which controls the Level.
.- SUBSONIC allows control from 15Hz to 35Hz
- BASS EQ allows control from 0dB to 10dB
- LOW PASS allows control from 35Hz to 250Hz
- PHASE shift allows 0 degrees to 180 degrees
LEVEL: allows you to match the amplifier 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 amplifier has detected a fault and will not operate.
There are several possible problems that can cause the amplifier 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.
The 1 channel mono amplifiers are capable of 4, 2 & 1 ohm loads and can be used in any
of the “bi-amplifier” systems described in the 2 and 4 channel Zeus and HFi amp manuals.
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.
Mono amps: 4, 2 & 1 Ohms.
BALANCED INPUT: Accepts balanced line inputs from 0.4 volts to 18 volts.
LINE INPUT: The Line Inputs are the RCA input jacks labeled “LINE INPUT”. This is where the Radio/CD player RCA outputs connect to. The Line Inputs accept
unbalanced RCA inputs from 0.2 volts to 9 volts.
LINE OUTPUT: The Line Outputs are a direct pass-through from the inputs. The RCA input signal from the radio/CD player is routed through the amplifier and out of
the Line Outputs. The outputs would connect to another amp Line Inputs in a multi-amp set-up.This allows you to daisy chain multiple amps from a single set of RCA
cables from the radio/CD player.
LEVEL: The input level control allows you to match the amplifier input sensitivity to the output level of the RADIO/CD player from 0.2 Volts to 9 volts when using
unbalanced RCA cables. The Level control needs to be adjusted to match the Line Level Sensitivity (this is the amount of voltage the radio/CD player RCA’s
provide. Example: If the radio/CD player Line Level Sensitivity is 4 volts, adjust the amp Level control to 4 volts.
SUBSONIC: The variable Subsonic filter is for subwoofer applications that require very low tuning frequencies typically around 15Hz - 35Hz.
BASS EQ: Variable Bass Boost from 0 to 10dB at a fixed 45Hz.
LOW PASS: Fully adjustable crossover from 35 to 250Hz.
PHASE SHIFT: The Phase Shift is fully adjustable from 0 to 180 degrees and this allows you to control the timing of the subwoofers. This is commonly used when
the subwoofers are installed in each front door.
POWER/PROTECT: The amplifier has built-in monitoring devices and protection circuits that monitor all vital functions of the amplifier. The Protection light
does not come on to indicate there is a failure, it comes on when it detects an improper operation. Common issues that cause
Protection status are:
- THERMAL: The amp has an internal temperature sensor that will automatically shut off the amp if it reaches dangerous temperature levels.
- OVER LOAD: If the amp is run at an improper impedance, the amp will shut down. If you are “CLIPPING” speakers / subwoofer(s), the light will blink to indicate a
hard clip.
- DC PROTECT: In the unlikely event the amp should internally fail, the amp will shut down to prevent a DC voltage output to the speakers or sub.
REMOTE: The HFR-3 Remote Module plugs into the Remote jack and allows you to adjust the Level.
MASTER/SLAVE: Allows for Linking/Strapping two amplifiers to a single subwoofer or multiple subwoofers that are wired together. (BRZ2100.1D and BRZ2400.1D)
