Lectrosonics HHa-941 Instruction Manual page 9

Gain
This setting is very important since it will determine the
audio signal to noise ratio and dynamic range that the
wireless system will deliver. Gain must be set accord-
ing to the individual voice, the mic capsule in use and
the handling technique of the user. LEDs in the control
panel facilitate accurate gain adjustment.

Freq.
The operating frequency is normally determined using
the scanning function in the receiver or with coordina-
tion software. The frequency is shown on the transmit-
ter LCD display in MHz and with a hexadecimal code
that is used on most Lectrosonics receivers.

The available modes are as follows. See Specifications
for the modes available in your model:
• Nu Hybrid/
Digital Hybrid
• Mode 3
• 200 Mode
• 100 Mode
• Mode 7
• Mode 6
• IFB Mode
NOTE: If your Lectrosonics receiver does not
have Nu Hybrid mode, set the receiver to Euro
Digital Hybrid Wireless® (EU Dig. Hybrid).
StepSiz
The frequency can be adjusted in 100 kHz or 25 kHz
steps to match the receiver. 100 kHz is the standard
increment for Lectrosonics wireless systems, but 25
kHz increments may be needed for use with systems
from other manufacturers or when frequency coordina-
tion requires it.

The Hex Code on the Main Screen will be smaller in
the 25 kHz mode and a fraction will appear next to the

steps is selected.
