Description
GAS MAD A1-70.4 is a powerful four-channel class AB amplifier, the acquisition of which will not cause financial bankruptcy.
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.
When bridged, you can use 2 x 220W for a four ohm load.
Good efficiency
GAS MAD A1 replaces the popular GAS Beat amplifier collection. MAD A1 amplifiers have been developed for a long time and have been improved even more than their predecessors. The end result is really successful!
First of all, attention is drawn to the aggressive cooling profile, which keeps the amplifier's temperatures under control, even if you command it with a heavy hand. You can forget about heat problems and focus on listening to music, because overheating of the amplifier can be left as a problem for other equipment manufacturers.
Better sound quality than before
The inside of the device is not overshadowed by the outer shell. Among other things, the balanced inputs reduce the noise produced by the amplifier and raise the sound quality of the amplifier to a level significantly higher than this price category.
Extensive adjustment possibilities
The adjustment possibilities of the MAD A1-70.4 amplifier are very good. You can use the amplifier to control, for example, two separate sets, with the separate sets' own crossover filters. Or alternatively, use the amplifier's second pair of channels to control the mids and the second pair of channels to control the trebles as active, using the amplifier's 12dB high-pass 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 call, but the amplifier starts automatically when it receives a signal, and an RCA output from which you can take the signal to the next amplifier.
