Loop Monitor Provides access to monitor actual loop current via a 3.5mm stereo headphone connector on front panel Channel A on left, channel B on right
Freq.response 80Hz to 6,5kHz
Automatic Gain Control The AGC is optimised for speech. Dynamic range >36dB
Distortion THD+N <0.2% 1kHz sine at full current
Metal Loss Correction Corrects system frequency response due to metal structures in a building. Gain constant  at 1kHz, adjustable gain slope from 0 to 4dB per octave in 0.25dB increments. Custom 2 slope MLC allows different slopes and transition frequency to be set via the menu. This does not compensate for signal loss from metal structures which can be significant.
