Broadcast Pix Slate 3000 Installation Planning Guide - October 2008
Page
The Broadcast Pix Slate system does not do any internal audio mixing, as powerful external audio mixers
are cost effective and readily available, however any Slate system can remotely control external audio
mixers through the MIDI (Musical Instrument Digital Interface) protocol. This method provides more
control and options for the user, compared to conventional switchers that use the antiquated ESAM
protocol, as MIDI works with many different types of audio mixers and is more powerful and affordable.
Examples of controllable audio mixers are: Yamaha O1V96, DM2000, Mackie TT24, and Roland RSS
M-400.
This option does not have to replace an audio operator, it can assist them. For example, when a clip from
the internal Broadcast Pix clip store plays on air, it can automatically turn on the sliders for the clip store
audio on the mixer, and when it goes off air the sliders turn off. Or, when an anchor on set is on air, it
triggers a scene change to bring up his volume, adjust EQ settings and add some compression.
All this is accomplished with the Audio-Follow-Video option from Broadcast Pix. For less demanding
productions, when an audio operator is not desired, the audio follow option may be configured to
completely take his place.
The Audio-Follow option includes a M-Audio MIDI to USB converter to connect your audio mixer to the
Broadcast Pix workstation through the MIDI In & MIDI Out ports, as shown below. If desired, you may also
use a straight USB cable, if your audio mixer accepts MIDI control over USB. Once connected, simply
enter your parameters in the command grid and start switching. Since the Broadcast Pix Slate system is
file based, these settings are saved on a show by show basis so every Broadcast Pix show that you
produce can have unique Audio-Follow commands.
