Basically they are identical – 4 heads switched into 1 speaker cabinet.
The AHS4 has an adjustable Line Level control for each amp, and a summed Line Level Output for feeding i.e. effects units.
The unit is totally transparent – the sound of the amps are not colored in any way – and switching is imminent and silent.
The unit runs on world-wide voltage (90-264VAC).
