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.

A low frequency rolloff filter can be set for a -3dB
point at 35, 50, 70, 100 or 125 Hz. Rolloff slopes are
12.2 dB/octave at 35 Hz and 10.1 dB/octave at 70 Hz
through 125 Hz.

The HH can be used with earlier Lectrosonics wireless
and IFB systems and systems from other manufactur-
ers by selecting the correct Compatibility Mode. The
receiver must be set to the same mode.

Hybrid
The available modes are as follows:
• Hybrid Digital Hybrid receivers
• Mode 3 (other brand contact the factory)
• 200 Mode Earlier Lectrosonics receivers
• 100 Mode 100 Series Lectrosonics receivers
• Mode 6 (other brand contact the factory)
• IFB Mode Lectrosonics IFB receivers
Tuning
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.

TxPower
Output power can be set to 100 mW to extend operat-
ing range (which can also suppress noise and drop-
outs to some extent) or set to 50 mW to extend the
operating life of the batteries.
