Stereo/FOCUS selection – ST-FOC
Via the “ ST-FOC ” menu, you can switch between stereo and
FOCUS operation.
In both operating modes, the corresponding transmitter has to
be set to stereo operation.
When the receiver is set to stereo operation, the left-right
signals are available as usual.
When the receiver is set to FOCUS operation, the left-right
signals are mixed and are available as a mono signal in both
headphone channels. With the

̄
rocker button you can
adjust the relative levels of the two separate channels in the
mixed mono signal (see “Adjusting the balance/FOCUS” on
page 17).
Limiting the volume at the headphone output –
LTD
Via the “ LTD ” menu, you can switch the limiter on or off. With
the limiter switched on, the volume at the headphone output
will be reduced.
Activating/deactivating the frequency boost –
HI-BST
Via the “ HI-BST ” menu, you can boost the AF frequency
response at 10 kHz by approx. 6 dB. As a result, headphones
with magnetic transducers sound better.
