Commissioning
The process for commissioning a loop system to the IEC performance
standard, IEC 60118-4, can be found in the user guide for the Univox FSM
2.0 eld strength meter, on the Univox
®
Certicate of Conformity or in the
equipment Logbook, if supplied. These documents are also available on our
websites.
1. Set the loop current to minimum by setting the control fully anti-
clockwise.
2. Connect the test signal source to the appropriate input.
3. Adjust the input level to the point at which the red, +12 dB LED ickers
sporadically in sympathy with the highest signal peaks. Where a 1
kHz sine wave signal is used the level should be adjusted to 0 dB LED
indication.
4. Follow the commissioning process.
General Notes
To listen to the sound quality, use high quality headphones with the FSM 2.0
or Univox
®
Listener loop receiver.
The ‘Monitor’ Output socket is a direct reection of the loop signal current
(volume control on rear panel). The sound quality can be easily assessed at
this point in the audio chain aiding set up and problem solving.
When operating at maximum output on some loop types the automatic limit
protection circuit may cut programme peaks. To rectify, reduce the loop
current accordingly.
To adjust the frequency response of the system use the ‘Parametric MLC’.
The degree of compensation is adjusted with the potentiometer and the start
or break frequency is determined by the 4 position switch marked: 100 Hz,
500 Hz, 1 kHz, 2 kHz. Start with the break frequency set to 2 kHz and adjust
the level. If this is not sufcient, move to the next lower frequency and repeat
as required.
