RX.GAIN knob/TX.GAIN knob/TX.ATT knob
Sets and displays and the gain for the transmitter or receiver. The knob name will change
depending on the connected device.
2 RF (Radio Frequency) signal meter
Shows bars to indicate the level of the RF signal.
An active antenna indicator is shown on the right side. It indicates which antenna is
enabled.
NOTE
The display will change depending on the device.
For more information about the relationship between the number of bars and the actual strength
of the signal, refer to the manual from each developer.
3 Battery indicator
Shows bars to indicate the remaining battery power.
NOTE
For more information about the relationship between the number of bars and maximum operation
time, refer to the manual from each developer.
4 OL indicator
Lights if the audio signal level of the receiver reaches the overload point.
NOTE
When the receiver is muted, is displayed on the MUTE indicator.
Relationship between analog and digital gain while Gain
Compensation is on
If Gain Compensation is on, adjusting the analog gain by a specific amount will cause the
I/O device to output to the audio network a signal that is attenuated by the same amount.
Therefore, the signals on the audio network will maintain a constant corrected level in the
digital domain.
For example, assume that the analog gain value has been set to +30 dB and Gain
Compensation is now turned on. Under this condition, if you raise the analog gain value to
+45 dB, the level of the signal sent to the audio network will stay at +30 dB (that is, attenuated
by –15 dB).
If the FOH console and the monitoring console are sharing one I/O device, adjusting the
analog gain on the FOH console will not affect the input level on the monitoring console. The
signal in the audio network is maintained at a constant level, and therefore increasing the
analog gain as much as possible will lower the relative noise floor and improve the S/N ratio.
The gain of each signal input to the QL series unit will be adjusted by the digital gain
parameter of the QL series console.
However, please note that if the signal is distorted due to a high level of analog gain, you must
first turn the Gain Compensation function off, set the gain to an appropriate input level, and
then turn the function back on. If you try to lower the analog gain level while the Gain
Compensation function is on, the signal on the audio network will be amplified by the same
amount due to the Gain Compensation function, and the signal will remain distorted.
NOTE
You can perform this operation rapidly if youve assigned Gain Compensation on/off as the SET
BY SEL function to one of the USER DEFINED keys.
