front with selectable VOX activation for a dynamic
microphone, such as the LBC 2900/15, as well as presets
for music ducking level and chime volume. Microphone
inputs 2 and 3 have XLR sockets with selectable phantom
power, and are mixed with the BGM. All microphone
inputs and the music source have their own volume
control, with a shared bass and treble tone control and a
shared master volume control.
Outputs
The powerful 120 W output section has two transformer-
isolated, 100 V constant voltage outputs for driving 100 V-
loudspeakers in two separate zones. The 100 V-technique
reduces line losses on longer distances and allows easy
parallel connection of multiple loudspeakers. Both zones
can be selected individually from the front panel, and the
output level for each zone can be individually set. Each
zone also has a low-voltage output for connecting 8 ohm,
transformerless loudspeakers (consumer-type). There is a
separate, 100 V call-only output for addressing an area
where announcements are necessary, but BGM is not
desired. A voltage-free call-active contact is available for
overriding local volume controls during priority calls, and
for other purposes. An LED meter monitors the output.
