Metal loss correction Corrects system frequency response due to metal structures in a building. Gain constant at 1kHz, adjustable gain slope from 0 to 3dB per octave. This does not compensate for signal loss from metal structures which can be significant.
Fault Monitoring Three LED fault indicators on the front panel:
Overload – delivering over the rated current
Overheat – unit is too hot (mutes output signal)
Loop error – short circuit / open circuit error
Ancillary To supply Ampetronic ancillary units +/-15V DC 0.15A power outlet on rear panel
Cooling Cooling is by natural convection from the product casing.
