GAS MAD A1-70.4, 4x70W Amplifier

The GAS MAD A1-70.4 is a powerful four-channel class AB amplifier that won't break your bank.

4 x 105W @ 2ohm
The amplifier offers 4 x 105 watts of power into a two-ohm load or alternatively 4 x 70 watts into a four-ohm load, thanks to the extensive adjustment options, you can get the sound exactly how you want it.
When bridged, you get 2 x 220W into a four-ohm load.

Good efficiency
GAS MAD A1 replaces the popular GAS Beat amplifier range. MAD A1 amplifiers have been developed for a long time and have been improved even more than their predecessor. The end result is truly successful!
First, the aggressive cooling profile keeps the amplifier temperatures under control, even when you push it with a heavy hand. You can forget about thermal issues and focus on listening to music, as overheating of the amplifier can be left to other device manufacturers.

Better sound quality than ever before
The inside of the device is not overshadowed by the exterior. Among other things, balanced inputs reduce the noise produced by the amplifier and raise the sound quality of the amplifier to a level significantly higher than in this price range.

Extensive adjustment options
The MAD A1-70.4 amplifier has very good control options. You can control two separate sets with the amplifier, for example, with the separate sets' own crossover filters. Or alternatively, use one channel pair of the amplifier to control the mids and the other channel pair to control the trebles actively, using the amplifier's 12dB high- and low-pass filters.
The amplifier also has its own clip lights for both channel pairs, which light up if the playback exceeds one percent distortion.
In addition to the RCA input, the amplifier also has a speaker-level input that does not require a wake-up, but the amplifier turns on automatically when it receives a signal, and an RCA output from which you can take the signal to the next amplifier.
