Note: On TriCaster 410, Mini SDI and Mini, only the first two inputs support analog audio.

Microphone – low impedance microphones and other common professional audio sources.

Microphone (Phantom) – microphones (typically condenser mics) requiring supplementary DC
power; not supported by TriCaster Mini.

Line – generally consumer audio sources such as CD players, VCRs, etc.

AES – digital audio (4RU models only).

SDI Embedded (or HDMI) – digital audio embedded with digital video transmitted via a Serial Digital
Interface (SDI) or HDMI connection (TriCaster Mini models).

For Microphone selections only, a Gain knob is enabled at right in the Hardware Configuration pane. This
provides additional trim for inputs, allowing you to bring input levels into a suitable operating range.
SECTION 15.5
COMMON CONTROLS
Many important features and optional settings are common to most source types, and some even appear for
outputs. Let’s review these before continuing.
15.5.1
MUTE
Mute switches for inputs and outputs appear as speaker icons located just above in the main Mixer panel. A
single switch controls multiple channels, as appropriate for that source. Enabling Mute removes the sound
from that source from all downstream audio mixes and outputs.
Hint: Muted sources still show signal activity on the VU meters, but levels are drawn in gray rather than
full color. This is also true for sources with Follow set that are not currently audible on output.
One important exception to Mute operation involves recording. TriCaster’s IsoCorder™ feature lets you
capture audio from the mixer, or directly from ‘same number’ inputs. That is, the audio recorded with the
video is taken from the matching number audio input, and routed directly to the recording module prior to
most adjustments in the Audio Mixer – including Mute.
Note: Audio 7 on 4RU systems is automatically muted when Linear timecode (LTC) is supplied (see Section
8.3). You can un-mute it briefly to adjust signal levels, but of course you don’t want this signal to be audible
during a live production – Solo might be useful in such cases.
15.5.2
TALK (TALK OVER)
It is often useful to reduce all other audio source levels so that an important announcement can be clearly
understood by the audience. The Talk button (also known as “Talk Over”) is only shown at the bottom of
input groups when the Connection Type is set to one of the Microphone options. Enabling Talk for a source
(typically a microphone) reduces the output level of all other audio sources by 20dB.
