Harrison Mixbus Virtual Broa cast Mixer (VBM)
1.0 Intro uction
Harrison Mixbus VBM is a clou -rea y virtual broa cast mixer. Base on Harrison Consoles
eca es-long experience pro ucing analogue an igital mixing consoles, VBM uses software
mixing technology evelope for Harrison's Mixbus DAW platform.
Figure 1 : VBM CONTROL PANEL
Mixbus VBM runs on MAC, Linux an Win ows platforms.
1.1 Premise
Mixbus VBM is a computer base igital mixer for live broa cast mixing applications. It is
tailore to applications that require multiple mix minus fee s an can provi e multiple program
outputs. It can be run locally or on a remote virtual server. Au io inputs an outputs to VBM are
over network connections an are not necessarily local to the broa cast engineer's physical
location.

2.0 Overview
Figure 1 shows the VBM control panel. In the figure left to right, there are 6 basic sections to
the panel.
1. Input an Bus List
2. Input Section
3. VCA Masters
4. Mix Minus Buses
5. Program Buses
6. Monitor Section
The Input an Bus List is selectable an can be hi en if not nee e . A itionally, VCA
masters will not be isplaye if none have been create .
2.1 Input Section
Figure 2 shows the input section of Mixbus VBM. The input section is comprise of several
channel strips, the number of which is limite only by the amount of your computing power.
Channel strips are a e by creating Inputs or Contributors.
Channel strips may be either mono or stereo. The ones shown in Figure 2 happen to be
stereo.
At the top of the input section are 4 buttons. They are:
1. Template – This button is use when starting VBM for a new project. It provi es a fast
metho of configuring a full mixing session base on a preset list of channels an
names. The user can either accept the efaults or mo ify them as nee e . Once rea y,
pressing the OK button will create the selecte channels in the mixer in one step.
2. A Contributor –
DEFINITION: A "Contributor" is an au io source that has a MixMinus bus correspon ing
to its input channel.
This button a s both an input channel an a correspon ing MixMinus bus. The
contributor may be either stereo or mono.
3. A Input – This button a s an input channel. The input may be either stereo or
mono. No MixMinus bus correspon ing to this input is create .
4. A VCA – This button a s a VCA master. When a VCA master is create , all
channel strips have a VCA assign button a e at the bottom. See Section 2.2.14.

2.2 VBM Channel Strip
Figure 3 shows a VBM channel strip. When a channel strip is create it can be chosen to be
either stereo or mono. The channel strip in Figure 3 is a stereo channel strip. The mono channel
strip is shown in Figure 4 an is i entical except for a pan control rather than a balance control
(see Section 2.2.6), an the level meter is a single meter rather than a pair of meters.
Features an functions of the channel strip are presente in the following sections.
