Roland V-60HD HD Video Switcher
72 STREAMING MEDIA April/May 2018
one pair of RCA outputs (Figure 3). Audio will
also automatically be embedded into the SDI
and HDMI outputs.
The input level for each XLR input can be
controlled on the console as well as in the menu
settings (Figure 4).
One of my favorite features is the input signal control for each of the XLR inputs: Head
Amp Gain, Digital Gain, and Input Level. The
Head Amp Gain allows you to properly set a
line- vs. mic-level gain on the raw audio signal
coming into the switcher, while the Input Level
allows you to fine-tune the input signal. Digital
Gain is used to control the SDI or HDMI digital
audio input; in my tests so far, I haven’t had a
need for it.
Each audio input has a dedicated equalizer
(EQ) to adjust the sound quality of each frequency band as well as noise gates and compressors. You can also adjust the audio frame
delay to perfectly sync the audio with the mixed
signal. Be sure to check how any added audio
delay affects the room mix.
You also have access to the audio channels
available on all six video inputs, discussed later
in this article. If you’re running microphones to
your cameras or other video equipment, you can
access these audio channels as well as the same
EQ adjustments available on the analog inputs.
Another favorite feature of mine is the Audio Embedding options. For the SDI outputs,
you can assign up to eight channels of embedded audio. The first two channels will always be
dedicated to the Master out (L) or Aux bus (L),
and the remaining six channels can record the
direct (“dry”) or processed (“wet”) audio from
the six audio inputs. With discrete channels of
audio, you have much more precise control of
audio mixing (or correction) in postproduction.
You can also control the Audio Follow mode
for each video input on the switcher. By default, Audio Follow is turned off for each of the
video sources connected to the mixer. As such,
the switcher will create a live audio mix of all
of the audio sources. If you want to automatically mute other audio inputs when switching
to a particular video input, you can turn on Audio Follow for that video input. You can also
assign any of the XLR audio inputs to a video
source with respect to Audio Follow as well.
