The through range of operating frequencies is 20 ... 30,000 Hz.
Input voltage UP - 0.25 V, UM - 1 V. Harmonic coefficient at rated output power UP - 0.2%, UM - 0.3%.
The rated output power of the PA is 2x12 W, maximum 2x25 watts.
The PA has an LED indicator of peak output power values "u200b"u200bwith an indication of 2, 4, 8, 12 and 16 W for each channel.
The dimensions of any UP or UM unit are 300x230x75 mm.
Weight UP - 2 kg, UM - 4.5 kg.
