The
Mk II Version is based upon the concepts and aesthetics of the original
FBS 1000 Mk I system. It's electronics have been totally redesigned, setting
new standards in Technical and operational performance as well as facilities,
thus making the Mk II version a more flexible product. Improvements over
the original system:
Audio connections to the Mixer
are balanced at + 4 dBu (on ELCO's)
Master level controls are in an
"active gain control" configuration, resulting in reduced noise
at low settings. The controls are 0 dB unity Gain at the centre which is
detented to provide an easily re-settable reference point.
Signal level indication at the
Master is by a three colour LED per signal path which illuminates Green
at - 16 dBu, Yellow at 0 dBu, and Red at + 16 dBu.
The Stereo Mixer station has a
MONO push-button on each channel to enable a mixture of Stereo and Mono
signals to be set up. This not only Mono sums the L - R signals but also
configures the mode of the PAN/ Balance pots. PAN for Mono, Full rotation
left results in around 4 dB level increase of the left side and full attenuation
of the right side (and vice versa ) BALANCE for Stereo Full rotation left
results in 4 dB increase in the left side and 4 dB decrease in the right
side (and Vice Versa ) giving a Stereo image shift.
Talkback to Mixer Stations, is
now controlled within the Master unit resulting in reduced bus - noise within
the Mixer Stations
Flexible Talkback control consists
of Jumper settable options
- No Talkback
- Talkback inject into channels and sum with channels
- Talkback inject into channels and sum with dimmed
channels
- Talkback replaces channels (i.e. Cuts channel
audio ) These options can be applied to a) Left Channel b) Right Channel
or c) Both channels.
- Return Talkback from the Mixer Station is balanced
at + 4 dBu. All return talkbacks are summed in the Master unit. h) Audio
Cabling is by means of industry standard 56 way ELCO's. Wiring is pin to
pin
- Power for the Master unit and Mixer Stations
is sourced from a separate Power Supply. All units are CE approved.
- The system consists of one Master which can feed
6 Wallboxes, One Power supply unit which will supply one wall box (plus
the master). Each wall box has outlets for 4 mixer stations. If more than
4 mixer stations are required then additional Power supply units can be
ordered and each one will power a 4 outlet wall box.
Each mixer station comes complete with its own
sturdy stand and two headphone mounting brackets.
Cables can be supplied or customer can wire his
own. |
