DESIGN FEATURES

1. Cast Aluminum Heatsink – The cast aluminum heatsink of the amplifier dissipates heat

generated by the amplifier's circuitry. The inherent advantage of casting provides a 30%

improvement of cooling over conventional extrusion heatsink designs.

REM Terminal – This spade terminal is used to remotely turn-on and turn-off the amplifier when

+12V DC is applied.

3. Power Terminals – The power and ground connectors on the amplifier are gold-plated and will

accommodate up to 4 AWG wire maximizing the input current capability of the amplifier.

4. LED Power Indicator – The LED illuminates when the unit is turned on.

5. Speaker Terminals – The heavy duty, gold-plated terminal block connectors (+ and –) will

accept wire sizes from 8 AWG to 18 AWG. These gold-plated connectors are immune to

corrosion that can cause signal deterioration.

6. bd Sync – The amplifiers have a 6 pin mini DIN connector. When operating two amplifiers in

the bridge mode, the SYNC cable must be used. This will allow the two independent frequency

carrier generators in each unit to be synchronized.

7. Punch Bass – The Punch Bass control helps correct for acoustical deficiencies in the listening

environment by helping produce full range sound without adding excessive boost.. The Punch

Bass control is a narrow band adjustment at 45Hz variable from 0dB to + 18dB. Connection is

made with a cable using RJ-45 and can be installed under the dash for remote control access.

8. Variable Crossover – The amplifiers have a built-in 24dB/octave Butterworth filter with a

crossover point variable from 50Hz to 250Hz. The crossover is set to Low-Pass (LP).

9. Subsonic Filter – A high pass filter designed to prevent frequencies below the audio range from

being applied to the subwoofer from the amplifier. Consequently, improving subwoofer

performance and power handling.

10. Phase – Used when connecting two bd amplifiers together to phase one amplifier 180° from the

other.

11. Gain Control – The input gain control is preset to match the output of most source units. It can

be adjusted to match output levels from a variety of source units.

12. RCA Input Jacks – The industry standard RCA jacks provide an easy connection for signal level

input. They are gold-plated to resist the signal degradation caused by corrosion.

13. Protect LED – The (red) LED illuminates when the unit is latched into protection. It requires

momentary AP removal to enable output PWM (Pulse Width Modulated).

14. RCA Pass-Thru Jacks – The Pass-Thru provides a convenient source for daisy-chaining an

additional amplifier without running an extra set of RCA cables from the front of the vehicle to

the rear amplifier location.
