Kenwood XH401-4 Class D Four Channel Power Amplifier 37A

High level inputs and automatic switch on

As an alternative to operation via RCA cable preamplifier input, the amplifiers of the XH series can also be connected directly to the high level outputs of an existing car radio. As soon as the signal obtained in this way is present, the amplifier switches on automatically and is therefore not dependent on its own control line for switching on.

Hi-Res Audio

The new power amplifiers of the XH series are capable of reproducing frequencies in the range above the otherwise usual 20kHz, thus also reproducing high-resolution audio data in the full bandwidth and with all details. In combination with a particularly low S/N level, high-quality recordings can be reproduced at an impressive level with the XH series.
