Loop amplifier Pro Loop NX7LOS
The Pro Loop NX7LOS has three mixable inputs. Two inputs process analogue microphone and line levels. For condenser microphones, 48 V phantom power can be switched in. The third input processes 100 V signals with priority over the other inputs.
With the two-channel amplifier, loop output B can be switched between 0° or 90° phase shift.
Like all AUDIOropa loop amplifiers of the NX series, the Der Pro Loop NX7LOS is primarily designed for continuous use. The integrated switching power supply and the Class-D amplifier design enables high efficiency with low waste heat and forms the basis for high reliability and operational safety.
- The functions of the induction loop and the amplifier are continuously monitored. Indicators on the unit and on the error output indicate functional errors.
- The Automatic Gain Control (AGC) ensures a constant level on the induction loop.
- Metal Loss Correction (MLC) can be used to correct the frequency response due to metal structures.
- Link connections allow several amplifiers to be combined into one unit.
- The output signal can be controlled via The output signal can be controlled via a headphone output.
- A screw-fixed cover prevents the setting from being changed.
