D-8 / Feb 2009

This is a 24dB/octave variable low-pass filter with Butterworth characteris-

tics, tunable between 1KHz and 20.2KHz. This filter is used to remove unwanted
high frequency artifacts (noise, squeaks, etc.) with minimal effect on the required
program.

Delay

Select the IN switch at the top of the DELAY slider to add delay to the current

source signal. The delay may be continuously adjusted in a range from 0-667mS
(20 NTSC frames). Delay may be added to correct for timing inconsistencies
between audio and video that create noticeable lip sync problems.

Bus-Minus Section

Bus-Minus offers the ability for every input fader to produce its own unique

Mix-Minus output. This section is where you configure what the talent or guest
on the other end of this output will hear. Typically you want them to hear a pre-
defined mix, minus their own voice.

To set up a typical Bus-Minus output you

will do the following:

• Turn ON the Bus-Minus output and set a

nominal output level.

• Press the “BUS-” button to remove the

fader’s own signal.

• Select a Base Mix. This is typically a

Master 1 or 2 bus but could be any
Mix-Minus 1-8 bus.

What the talent hears is the base mix, minus

their own voice.

Bus-Minus Controls

Bus-Minus ON Switch - select this to

enable or disable the fader’s Bus-Minus out-
put.

Output Gain Slider - adjust Bus-Minus

output level.

Meter - will display the audio level at the

Bus-Minus output.

PFL Switch - press this switch to listen to this Bus-Minus output.

Bus-Minus Mode - select one of four mutually exclusive operating modes:

• Bus+: destination hears themselves along with the Base Mix.

• Bus-: destination hears the selected Base Mix, minus themselves.

• DIR PRE: destination gets a direct, pre-fader clean feed of the input fader.

• DIR POST: destination gets a direct, post-fader clean feed of the input fader.

Base Mix - select a mix on the surface you wish the destination to hear. Choose

from one of the two master outputs and the eight Mix-Minus busses.

Note: Butterworth Filters
typically yield excellent
flatness, no ripple in the
pass band, and a rounded
amplitude response near
the cutoff frequency.
