Attenuator (Volume Control)
ATT-0407 & 0501 & 1000 Series
he ATT series attenuators
have been designed to offer
an attractive low profile
T
appearance when flush mounted.
The units have a snap fit fascia
plate, which neatly masks any
unsightly fixing screws. A low
profile 12 position (including off)
rotary switch has been employed
with 'Smooth-Click' for a very high
quality feel when operated. The
rotary switch does not have a stop
position and can be operated
continuously through maximum
and off positions. High quality auto
transformers have been used in
order to give excellent frequency
response, low insertion loss and
reliability, when attenuating a high
impedance signal.
Power options available are 50 &
100 watts at 100 volt line or 40 &
100 watts at 70.7 volt line.
Additionally an option for priority
relay is available (See spec. sheet
overleaf). This enables an
emergency or priority paging
announcement with full volume to
bypass the attenuator, e.g. when
background music is being played
at low volume or the attenuator is
in off position.
Unique Low-profile design.
