5 Channel D Class Amplifier - (70W x 4, 500W x 1) High

Pass Filter 12dB.oct Filter Frequency 40Hz-400Hz(front) 40Hz- 4kHz(rear) / Low Pass Filter Filter Frequency 80Hz-4kHz(front) /

Max Sensitivity 200mV-6V dB / RMS Power at 14.4V: Watts per channel NOT bridged @ 1 kHz 4 ohms 70 x 4 watts 2 ohms 100 x4 watts / Watts per channel bridged
4 ohms 200 x 2 watts

The PA D5000.5 is capable of bridging two full-range channels into a single full-range channel with higher output power. For instance, the front channels (FL and FR) when wired correctly will increase the output power from 70W per channel to 200W per channel (for a 4 ohm load). The same can be done for the rear channels (RL and RR). The most common configurations are four full-range channels and a subwoofer channel, or two bridged full-range channels and a subwoofer channel.

 Super-efficient class D design�Runs much cooler than conventional amps.

High-speed MOSFET switching�Power supply with outputs stable into 2 ohm loads for full range channel speakers and 1 ohm loads for subwoofer channel.

Protection�Thermal, DC offset, reverse DC voltage and short circuit protection.

Sub 1/Sub 2 Inputs�Line level inputs for subwoofer signal from head unit

SUB/INT source switch�In the INT position, the amplifier will filter the bass frequencies from the full range signal and send them to the subwoofer amplifier channel.

SUB sonic filter�Attenuates the frequencies below the settings on the control.

Remote bass level control�Set gain to match output from head unit.

 Rear Full, HPF switch�Selects between no filtering or a high pass filter to dial in your speakers� blending.

Channel mode switch (4CH/ST)�In the ST position, the amplifier sends the same signal to the front and rear channels.

Nickel-plated wire terminals & RCA connectors�Ensure maximum signal transfer.

Stainless steel hardware�Used throughout won�t corrode in humid environments.
