- Page 1 VR AMPLIFIERS VR AMPLIFIERS For the VR705D amplifier please refer to the Class AB technology for channels 1-4 and Class D technology for the 5th channel. SPECIFICATIONS SPECIFICATIONS 150mV-3.2V 240Mv-6V VR Series...
- Page 2 Fans should be used in correspondence with an escape duct for heat when mounting the amplifier in an enclosed or restricted area. Avoid slipping and scratching your new Crossfire amplifier by pre-drilling the mounting holes with either an 1/8" or 3mm diameter drill bit when using the screws supplied in the accessory kit.
- Page 3 All Crossfire amplifiers are designed to work within 10.5 to 16 volts DC. Therefore, as a precaution, the vehicle's electrical system should be checked for correct voltage supply with the help of a voltmeter. First, connect the test leads of the voltmeter to the battery terminals with the ignition of the vehicle in the off position. The voltmeter should read no less than 12 volts.

- Page 7 "ON" position, 6dB of boost centered around 45Hz will be added. In the "OFF" position no boost is added to the output signal. This boost switch is available on specific models only. Please see specification chart for verification. Crossfire highly recommends using this feature only on amplifiers powering subwoofers.
- Page 8 Separate to the VR705D only is a "Sub Input" selector switch. With this switch positioned to "CH 1-4" the fifth channel will sum to the signal input of "CH 1-4". Please see diagram in PG-7 for more information. Or if you have any doubts please call your authorized Crossfire dealer or contact Crossfire directly...

- Page 11 Bridging the two like amplifiers together is fairly easy. Study the following instructions as well as the diagrams on PG-10 to assure proper connections. If you experience any difficulties, please contact Crossfire's Technical Assistance at 562-906-0800. BRIDGING CIRCUIT (Invert output) The internal bridging module can only be used when a pair of either VR1000Ds or VR600Ds are used.
- Page 12 200 amps to make the same power. A normal stock automobile sees it differently, 120 amperes is a very high amount of current and very taxing on its electrical system. We at Crossfire strongly suggest using one dedicated, high quality, battery per 1000D amplifier or per two 600D amplifiers. We also recommend upgrading the vehicles alternator whenever possible.
