CONGRATULATIONS Congratulations for choosing a Viper Audio power amplifier from Directed Electronics, the industry leader in high quality automotive security and audio equipment since 1990. With the introduction of Viper Audio power amplifiers, Directed Electronics continues to set new standards of performance, reliability, and affordability in the mobile electronics industry.
LIMITED TWO-YEAR CONSUMER WARRANTY Directed Electronics, Inc. promises to the original purchaser, to replace this product should it prove to be defective in workmanship or material under normal use, for a period of two years from the date of purchase by the dealer as indicated by the date code marking of the product PROVIDED the product was installed by an authorized Directed dealer.
FEATURES Super-efficient Class D PWM design runs much cooler than conventional amps. Continuously variable 24 dB/ octave low-pass crossover. Variable 20-50 Hz, 24 dB/octave subsonic filter. Variable 12 dB bass EQ function. Variable phase adjustment. Remote subwoofer level control supplied. Master/slave RCA jack functions support two amps bridged to one load. Variable input sensitivity optimizes match with different signal sources.
INSTALLATION GUIDELINES 1. Please read this owner’s manual carefully before installing this amplifier. 2. Disconnect the battery ground terminal prior to making any electrical connections. 3. Check for any hazards or obstructions such as gas tanks, fuel or brake lines, and wiring harnesses before mounting the amplifier. 4. Pick a mounting location that will provide adequate access and ventilation and protect the amplifier from heat, moisture, and dirt. 5.
speaker load, the more heat is generated. For low-impedance speaker applications or restricted ventilation installations, an external cooling fan may be advisable. 9. Battery and ground connections to the vehicle should be made with crimped ring terminals of the appropriate size (surface area is what counts); soldering the terminals after crimping is also recommended. 10.
FRONT PANEL CONNECTIONS 3. RCA Bridge Output Jack - This output sends an out-of-phase signal to a slave amplifier when connected in the External Synced Bridged combination. (Refer to the Combined Amplifiers section of this guide.) 1. RCA Input Jacks - Accepts line level outputs from head units or signal processors at voltages between 150mV and 8 volts. 2.
REAR PANEL CONNECTIONS 1. Remote Turn On - This terminal turns on the amplifier when (+) 12 volt is applied to it. Connect it to the remote turn on lead of the head unit or signal source. If a (+) 12 volt remote turn on lead is not available, a Remote Power Adapter (P/N #55000) can be used to supply a remote turn on signal. DO NOT connect this terminal to constant (+) 12 volt. 2. Sub Out Terminals - Connect subwoofers to these terminals. (Refer to the Speaker Wiring Diagrams section of this guide.) 3.

TOP PANEL CONTROLS 1. Input Gain Adjustment - Controls the amplifier’s sensitivity and is used to match the input level of the amplifier to the output level of the signal source. 4. Sub Phase Adjustment - Controls the phase of the subwoofer output from 0 to 180 degrees. 2. Crossover Frequency Adjustment Adjusts the crossover point for the on-board active crossover. 5. Subsonic Frequency Adjustment Adjusts the cutoff point for subsonic frequencies.
TOP PANEL FEATURES Control Panel Cover The amplifier’s gain and filter controls are mounted under the elliptical control panel cover. Magnets hold the cover snugly and allow easy access. To install the cover - Place the straight end of the control panel cover into the notched end of the amplifier’s top panel while elevating the curved end. Lower the curved end of the cover until the magnets make contact.
SPEAKER WIRING DIAGRAMS Single subwoofer connection (bottom view) Two subwoofer connection (bottom view) NOTE: The dual + and -- subout terminals of the d600.1/d1200.1 are paralleled internally and the combined load impedance should be taken into consideration when connecting multiple subwoofers.
COMBINING AMPLIFIERS The Viper d600.1/d1200.1 subwoofer amplifiers have the capability of connecting two or more amplifiers of the same power rating together in a master/slave combination for increased power with accurate level matching. They are the Parallel Synced Gain and External Synced Bridged combinations. WARNING: DO NOT attempt to combine amplifiers of different power ratings. These amplifier combinations work correctly only if the master and slave amplifiers are identical models.
PARALLEL SYNCED GAIN CONNECTIONS/SETTINGS 1. Input Signal - Connect these RCA jacks as described in the Front Panel Connection section of this guide. 2. Slave/Master Switch Set the slave/master switch on the master amplifier to the MASTER position. Set the slave/master switch on the slave amplifier to the SLAVE position. Setting the slave/master switch on both amplifiers will automatically set the I/O RCA jack configuration according to each amplifier’s slave or master designation. NOTE: 4.

MULTIPLE AMPLIFIER COMBINATIONS The Viper d600.1/1200.1 subwoofer amplifiers can also be used in multiples of the master/slave combinations allowing for unlimited expansion to a systems subwoofer section. To use multiples of amplifier combinations the following directions must be adhered to for best results. Audio signal - Divide the head unit or processor audio signal to the master amplifiers by using RCA Y adapters.
CROSSOVER SETTINGS AND GAIN ADJUSTMENT Your Viper Audio power amplifier needs to be adjusted carefully to achieve maximum performance. These are some guidelines to follow when fine-tuning the amplifier. 20 Because this amplifier is only designed for subwoofer applications, the low-pass crossover is active at all times. The crossover point is adjustable to allow more precise system operation.
