START/STOP FUNCTIONS CONFIGURED
The 'Start' is only active when this is activated in the software.
These remote connectors are activated by the fader and/or `ON' switch in the channel module. The start
jack connectors are electronically separated by use of encapsulated reed relays.
Reed relays are ideal devices for eliminating ground loops and limited life span effects of other switches
and can easily be interfaced with all modern equipment.
The start connectors are connected to separate reed relays.
The maximum VOLTAGE/CURRENT is 24v/50mA. (Polarity is not important with reed relays!)
NOTE 1:
Nearly all of the modern devices require pulse information. Continuous signals
however, can have the advantage that during broadcast a CD player cannot
be accidentally stopped. One disadvantage however is that some CD players
are blocked from other functions when started with a continuous pulse.
NOTE 2:
It is advisable to only use the pulse start mode with jingle machines. The cart
has to finish its tape to the end and then automatically rewinds.
NOTE 3:
Some of the older products such as the A-77, require additional relays or
switching transistors to operate satisfactorily, contact your dealer for more
information.
MIC/LINE GAIN
The Gain control (only active when the line input is selected) adjusts the gain of the stereo channel pre-
amps, within a range of -20 dB to +20 dB for the line level and +/-40 dB for the Mic level. The range of the
fader (VCA) gives an additional 10 dB of gain when needed.
Alignment of the LINE input of a channel
To align the line input of a channel close the fader and activate the cue switch. The gain control is used to
adjust the level of the incoming signal until a 0 dB reading is achieved. If the `ON' switch is now activated,
the signal level will be nominal. When the fader is opened, the CUE signal will be automatically reset, and
its associated LED will switch off.
