Phoenix Gold ZXM700.5

The Phoenix Gold ZXM700.5 is an exceptionally compact 5-channel Class D power amplifier designed for car audio systems in which four speakers and a subwoofer are to be powered by a single amplifier. Despite its small size, the ZXM700.5 delivers high output power, making it ideal for high-performance complete systems with limited installation space.

The four main channels deliver up to 4 × 100 watts RMS into 2 ohms, while an additional 350 watts RMS into 2 ohms is available for the subwoofer. This allows, for example, front and rear speakers to be powered along with a subwoofer by a single power amplifier.

Thanks to the efficient Full-Class-D technology, the enclosure remains extremely compact at just 186 mm in length. Separate filters for the front/rear channels and the subwoofer allow for precise adjustment to the speakers being used. An adjustable bass boost at 45 Hz is also available for the subwoofer channel.

In addition to standard low-level signals, the ZXM700.5 also supports high-level input signals. This allows the power amplifier to be integrated into vehicles equipped with the factory radio or factory sound system. When using the high-level input, an automatic power-on function is also available.

A bass remote control is included, so you can easily adjust the subwoofer level from the driver's seat.
