B2 Audio Zero.5 Owner's Manual

OWNER’S MANUAL Zero.5

Every product developed by implements the keystones of our company philosophy; Optimum sound reproduction within its range, etter ass & high performance. These elements will enable you to reproduce music the way you prefer. Our amplifiers features a unique design, a variety of applications & highest possible effiency combined with a clean analytical sound. To obtain the full potential of the amplifier, it is strongly recommended & necessary to upgrade the stock electrical system in order to operate correctly & minimize failure. It is therefore essential to read through the whole manual to ensure optimum operation. Installation can preferably be carried out by an authorized dealer.

Power @ 4 (12V & 14.4V < 1% THD) Power @ 4 linked (12V & 14.4V < 1% THD) M1S 500 W x 1 1000 W x 1 Specifications (detailed) 2) The amplifier has a 4 stage advanced protection circuit; -Thermal protection, Voltage sensors, DC offset & short circuitry via speaker outputs. The Zero.5 utilizes a double sided SMD pcb & high current mosfet switching devices in both the in- and output stage. A 4) wired remote level control with clip indicator is included with the amplifier. - This unit will enable remote gain adjustment. - For more advanced features like selectable bass frequency, boost level & gain, the Better Bass Remote (optional) can be used. 5) The crossovers of the Zero.5 are variable 24 dB/octave filters for both low pass & subsonic. Specifications Continious output power rating (RMS) The Zero.5 operates stable @ impedances of minimum 1 mono. - Running the amplifer at that impedance sets requirements to both ventilation & the battery system. Operation below minium impedance will void the warranty. 1) 3) 3 1000 W x 1 2000 W x 1 Power @ 2 Power @ 2 linked : 30 ~ 80Hz Power @ 1 2000 W x 1

input of 0.2V is essential for correct operation. POWER & PROTECTION INDICATOR Power LED, Blue-lit shows correct operation. Protect LED, Red-lit shows general malfunction, faulty connection or thermal protection. GAIN (6V ~ 0.2V) Matching of the output voltage from the head unit’s RCA line-outs to the input section. SUBSONIC FILTER (10Hz ~ 50Hz @ 24dB/Oct) Adjusts the subsonic cut off point to eliminate frequencies within the filter’s range. REMOTE LEVEL CONTROL PORT Connection of external level control. (The Better Bass Remote can be connected for additional features). OUTPUT MASTER / INPUT SLAVE For daisy chain connection of 2 Zero.5 amplifiers. Minimum impedance is 2 . Output signal can be routed from 1 master amplifier to 2 slave amplifiers, by setting the switch to SLAVE1 & SLAVE2 on the amplifiers in question. DO NOT USE IN DAISY CHAIN MODE! LOW PASS FILTER (35Hz ~ 250Hz @ 24dB/Oct) Adjusts the cut off point for the low pass filter within the filter’s range. PHASE CONTROL Variable phase adjustment from 0-180 degrees. 4 2. Panel layout BASS BOOST Variable bass boost with 0-9dB. BASS FREQ Variable bass boost frequency from 30Hz ~ 80Hz SPEAKER OUTPUTS Amplifier connection to the loudspeakers. Minimum speaker cable is 12 gauge. Minimum impedance for the Zero.5 is 1 if used as a single unit. In a daisy chain configuration the minimum impedance is 2 . Zero.5 BASS BOOST 0dB 9dB BASS FREQ 30Hz 80Hz MASTER SLAVE1 SLAVE2 SWEET LIKE DANISH

For connection to the chassis’ ground. For optimum performance 0 gauge cable is required, all of them using common ground connected with cable of equal length. REM (REMOTE) Connect to switched +12V from the head unit. 5 Installation of the amplifier should be done in the folling steps: 1. Ensure that the ground is appropriate, then connect it to the amplifier. 2. Next step is to connect the +12V wire. Ensure all power terminals are used. This cable has to be fused at the battery & the amplifier for safety precautions. 3. The final step is connecting the switched remote. 4. Operation over 18V will cause the amplifier to go into protect mode. CAUTION 2. Panel layout +12V (POWER CONNECTION) For connection to the positive terminal of the battery (+12V). For optimum performance 0 gauge cable is required. Zero.5
