For instructional videos on wiring the HDBR, please visit our YouTube channel at HDBR SPECIFICATIONS HDBR FEATURES 1 Maximum Input Level.............................................................................................15V rms Maximum Output Level......................................................................................13.5V peak Frequency Response......................................................................10Hz - 100KHz; +/-1dB Total Harmonic Distortion.........................................................................................0.003% Signal to Noise Ratio.................................................................................................130dB Balanced Input Noise Rejection.................................................................................>60dB Input Impedance.....................................................................................................10 Kohm Output Impedance................................................................................................150 Ohms Power Supply......................................................................................High headroom PWM Power Draw...............................................................................................................150mA Recommend fuse rating..............................................................................................1 Amp Bass Driver: The HDBR contains a Bass Driver circuit that accurately recreates and injects Low Frequency information back into the signal path. What that means in everyday terms is that the HDBR will give more bass impact to your best compact discs or lowest quality recordings. Bass Equalization Circuit: The HDBR has a unique equalization circuit that contours the restored bass to your speaker systems. Dash Mount Remote Control: The HDBR comes with a Dash Mountable Remote Control that allows you to enjoy the effects of the HDBR without having to leave the drivers seat. The Dash mount Control has an LED indicator that will grow brighter as you add more bass or dimmer when you decrease it. Bass Maxximizer Indicator: Not only does the HDBR provide good music to your ears, but it also gives you some visual enjoyment as well. On the chassis of the HDBR there are three LED indicators that flash when the bass maxximization circuit is activated. Bass Output Control: The HDBR has the ability to produce large amounts of deep, ear blowing bass without damaging your speakers. The Bass Output Control circuit allow the HDBR to maxximize the bass output of any autosound audio system while restraining destructive bursts.

FREQUENCY RANGE: This knob allows for you to adjust the range of frequencies from your center point. All the way to the left will include the maxximum frequencies to maxximize, while all the way to the right will enhance only a limited amount f frequencies near your CENTER FREQUENCY. OUTPUT LEVEL CONTROL: This knob allows for you to control the amount of signal voltage you are sending through the RCA OUTPUTS to your amplifier(s). It is important to note that the MBC1 has a built in line driver capable of sending an ‘ultra clean’ 9 volts of signal output to your amplifier(s). Be sure to reference the end panel silk screening for GAIN/LEVEL CONTROL on your amplifier(s). Some amplifiers cannot handle the full 9 volts and going beyond the specified Input range on your amplifier(s) can be damaging. GROUND ISOLATION: Occasionally alternator whine may appear in the system because the source unit and amplifier may use different grounds. To help in this situation, we have provided alternative grounding options. MAKE SURE THE SYSTEM IS OFF BEFORE SWITCHING THIS SELECTION! RCA INPUT: In most cases you will leave the selection switch in the BALANCED position. In some systems the source unit may look for a ground through the RCA connections. In this event you would switch the selection to UNBALANCED. INPUT: RCA’s from source unit connect to this location. OUTPUT: RCA’s from the HDBR connect to the inputs of your amplifier(s). REMOTE: The BPR-1 Bass Processor Remote dash mount control connects here. This remote allows for complete control of your audible subwoofer level along with a LED indicator which brightens as you increase bass enhancement. REM / 12V / GND: -REM: Connects to a 12V+ switched source. The REM cable should have 12V when the source unit is on and 0V when the source unit is off. Typically this would connect to the ‘Power Antenna’ output wire on the back of your source units’ wiring harness. -12V: Connects to a 12V constant source. The Po...
