ProDesk-4 OWNER’S MANUAL

SOLO-LINKING and Mute-All
Solo Linking
The ProDesk can connect to other consoles using the Bus Input and Output jacks; this allows the user to combine the audio from
multiple consoles to create a larger overall mixer. APB consoles are equiped with Solo Linking connectors to also tie the Solo systems
of the combined consoles together.
Two 5-pin DIN connectors are provided that allow the Solo systems of multiple APB consoles to be linked together. Thus, a single set of
headphones can be used to monitor the solo functions of multiple mixers. This Solo-linking can also be used with a larger APB Spectra
console if it is fitted with a Solo Linking option, or any of the smaller ProRack series or mixers.
Use a 5-pin circular DIN cable to link the OUT connector of the Slave console to the IN connector of the Master console. Any Solo
activity on the Slave console will still show up on that console but will now also activate the Solo function on the Master console where
the Slave’s solo audio can be heard, mixed in with any Master Solo activity.
The DIN cable should be wired pin-to-pin with an overall shield tied to the connector shells on each end.
Contact APB about where to obtain a Solo-Linking cable.
Mute-All
The ProDesk has the ability to mute all of the 18 main XLR outputs with a single external command. This feature can be used when the
PA system is required to be silenced during safety announcements* or if a system-wide mute is needed for any reason.
The 2-pin Phoenix connector can be configured to activate the Mute-All command under the following conditions:
A) Mute-All activated when the pins are shorted together (console powered)
B) Mute-All activated when the pins are not shorted together (console powered)
C) Mute-All activated when more than 3V AC or DC is present on the pins (opto-iolated)
D) Mute-All activated when less than 3V AC or DC is present on the pins (opto-isolated)
For conditions A & B, power is supplied from the console and approx 3V DC appears across the pins. This voltage can then be
controlled by an external relay or switch to perform the Mute-All function.
For conditions C & D, the 2 pins are totally opto-isolated from the console and an external voltage can be used to activate the function.
Any voltage from 3V to 24V, AC or DC (either polarity) can be used.
To indicate that Mute-All is active, the Status LED located with the master meters will blink Red once per second and the 4 LED meter
arrays will turn off. The meters and outputs will return to normal operation once the Mute-All command is removed.
See the following page for information on configuring the Mute-All function.
