LOW Q
Page purpose:
TRX9xx ONLY
- This page controls the quality of the received IFB signal.
Parameters:
•
LOW Q
– enables reception of timecode, remote control signals and IFB audio if the unit is so equipped.
•
HI Q
– enables high quality audio and disables timecode and remote control reception while still
allowing local recording.
IMPORTANT:
All units
MUST
be using the same format to function correctly.
IMPORTANT:
Any change made to this page requires a reboot before the new setting will take effect.

To use this function, you will need a second IFB100 that is also connected by audio cable to your cart and placed
some distance away in the direction you expect Talent to travel. Set the frequency of this second IFB to 2 MHz
above (+ 0.002 GHz on the
IFB Frequency page
) the first unit. Also be sure to set the
IFB Frequency page
on
the Audio Transmitter(s) (i.e. TRX900) to the lowest frequency assigned to the two IFB100s.
In operation, the first IFB100 will be closer to (or on) your cart and the second IFB100 will be some distance away
to cover the area you anticipate using. While the audio transmitter(s) (i.e. TRX900) is within range of the first
IFB100, it will be receiving IFB audio on that lower IFB frequency. Once the TRX900 has gone out-of-range of the
first IFB and gone into-range of the second IFB, the TRX900 IFB receiver will switch to receiving on the frequency
assigned to the second IFB. If over time, the unit moves out-of-range of the second IFB and back into-range of the
first IFB, the TRX900 will once again start receiving on the first IFB’s assigned frequency.
