Polk PA D5000.5 Super efficient class D bridgable 5-channel mobile audio amplifier
Sleek, Compact, Powerful
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.
PA D5000.5 Features:
- 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 and will not corrode in humid environments.
