Earthing
Earthing of units with mains supply (class I equipment) is performed via
the protective earth (PE) conductor integrated in the mains cable. Units with
battery operation (< 60 V, class III equipment) must be earthed separately.
Earthing the unit is one of the measures for protection against electrical shock
hazard (dangerous body currents). Hazardous voltage may not only be caused
by a defective power supply insulation, but may also be introduced by the
connected audio or control cables.
If the unit is installed with one or several external connections, its earthing
must be provided during operation as well as while the unit is not operated.
If the earthing connection can be interrupted, e.g. by unplugging the mains
plug of an external power supply unit, an additional, permanent earthing connection must be installed using the provided earth terminal.
For additional information on earthing, please refer to the Operating Instructions file on this same CD.

In addition a talkback signal with separate volume control can be enabled
and brought to the guest headphones, heard in split mode and controlled via
a GPO signal.
Two types of general-purpose desktop boxes in the OnAir 2500 design, both
with an illuminated key, and one of them with three additional LEDs are
available for many different applications, e.g. cough key, control of external
devices, etc. The keys may directly be connected to GPIs, the LEDs to GPOs,
and configured for the respective task in the configuration menu.
Compact Monitoring/TB Module:
The compact monitoring/TB box offers an array
of configurable keys for monitoring source
selection and talkback destinations, red light
indication, and studio loudspeaker/headphone
control. Talkback between any locations is possible, as well as to external lines, the master,
AUX, and N–X outputs, but needs to be configured as desired.

Studio Source Selection
Studio Muting
Talkback
Selection of the studio monitoring source can be done on the CR desk or on
the compact monitoring/TB box.
The studio monitoring speakers are automatically muted if at least one of the
microphones in the studio (Configuration: Input Location = Studio2) is on.
The studio headphones are not muted in such a case.
During talkback from studio to CR and vice versa, the studio speaker level
is automatically dimmed. The talkback signal from CR to studio is not
dimmed and has the normal listening level on both the studio speakers and
headphones.

GPIO Break-Out Box
(order no. A949.0588)
16  Quick Reference Guide
Document generated: 09.09.14
OnAir 2500 Digital Mixing Console
For easier wiring of single GPI and/or GPO signals, this break-out box can
be used. 16 GPI signals and 12 of the 16 GPO signals of a GPIO card with
relay outputs (A949.0436) are wired to single, 4-pin ‘Combicon’ terminals
(see below), providing the relay contacts or opto-coupler inputs, as well as
GND and a short circuit-proof 5 V DC supply.
If voltages exceeding 50 V (AC or DC) are switched, the break-out box must
be placed within a closed rack in order to avoid shock hazards by touching
the contacts.
Four of the 16 GPO signals (GPO 1...4, marked in black on the front panel)
are connected to solid-state relays whose power terminals are wired to the
‘Combicon’ terminals. These power contacts can switch AC loads from
24...240 V with a maximum total current of 5 A over all 4 relays.
For safety reasons, these four terminals have no additional GND and 5 V
supply. All remaining low-voltage terminals (GPI 1...16, GPO 5...16) are
coded on pin #4 in order to prevent high-voltage connectors being inserted
by mistake.
The high-voltage connectors must be coded, as shown below; six coding
elements (order no. C054.251100) are included with the break-out box.
Coding Element
Eight 4-pin ‘Combicon’ plugs with screw terminals (C054.251104) are
included with the break-out box. If more plugs are required, please order
separately. On the rear of the box two 37-pin D-type sockets (f) are provided
for connection to the GPIO card. For matching cables please refer to the table
below.
