MIXER APPLICATIONS

Telephone hybrid

Use a telephone hybrid to open the show up to interaction with the outside world. A

hybrid allows you to receive phone calls and send them to your mixer as audio. Connect

the hybrids audio output to the mixers telco channel (channel 5) and connect the channel’s

clean feed output to the line input on the hybrid. The mixer has been designed to work with

the SONIFEX HY-03.

On-Air Light

The On-Air light, also known as Mic Live,

is used to indicate to everyone inside or

outside of the Control Room and/or Studio

that microphones are live and on-air. A set of

latching relay contacts, activated by a control

room mute, are available on the Talkback 9

way D type socket on the rear panel of the

mixer for the Control Room On-Air light.

See the pin-outs of the talkback interface

for details. Shown below is an example of

connecting the latching relay contacts on

the talkback interface to a SONIFEX RB-LC3.

The remote connection on the RB-LC3 is

active low.

Mic Cue Light

The mic cue light is used to indicate to a guest, etc, situated in a talks studio, that they

should speak. The cue light is usually green, and there is usually one per microphone. This

should not be confused with a mic live light, which is red and there is one per studio or

control room, also known as “On Air light” (see above).

Open collector outputs for each channel are provided on the Remote Connectors. See the

remote connectors section for details

NOTE: It is vital that mains voltages are NOT connected to any of the connectors on the

mixer. If your On-Air light is to be mains operated then you should use a suitable opto-

isolated solid-state mains relay. The SONIFEX RB-LC3 Light/Power controller is a suitable unit

that will control up to three On-Air lights and/or Mic cue lights.

Voice Processors On Mic Channels

To use an outboard eects unit with a microphone, for example, a voice processor an

auxiliary bus could be used and returned through a spare input channel.
