Installation
Deciding where to install
In a live situation, it depends on whether the live engineer wants to be able
to see the BBR interface or not and whether you intend to utilise the Virtual
Sound Check facility. The analogue cable looms supplied with the standard
unbalanced unit are 3m long so if you’re planning on mounting the unit in a
rack close to your console then that will be the deciding factor. However,
some people will prefer to install it close to the stage box. It’s best to install
it at eye level for ease of operating the menus.
How to wire the BBR into your console
The BBR1U is supplied with 3 analogue breakout looms that are designed to
plug directly into the insert points on your mixing console. Each loom is
terminated in 8 labelled TRS ¼” jacks which have both the send and return
signals (on tip and ring respectively with the sleeve being the ground
connection). The advantages of plugging into the insert break points are:
a)
you are as close to the mic amps as possible (and therefore will be
recording the cleanest signal), and
b)
you can use the BlackBox as a Virtual Sound Check device.
However, some people will prefer to take their signal from group or direct
outputs or other places within the signal chain of the mixing desk which is
fine. The BBR1U BlackBox Recorder accepts unbalanced audio (as this is
what most insert break points provide), and can be switched between
Low
and
Pro
levels in the Setup Menu (page 26).
