Stereo linking (inputs)
When active for stereo sources such as stereo microphones, linked
inputs are hard panned to the left and right bus. Controls including
gain (trim), fader, high pass lter, delay, limiter, mute, and routing are
controlled together.
Solo
A control on a mixer to route a channel to headphones while muting
all others. Solo and PFL are related controls and in many consoles are
the same. Solo circuits can be exclusive—only one channel is sent to
headphones at a time—or non-exclusive—any number of channels can
be sent to the solo circuit and appear in headphones.
TA-type connector (TA3, TA4,TA5)
Miniature XLR-type, locking connectors. TA3 connectors are used
by Sound Devices for various inputs, outputs, and as balanced and
unbalanced connections. TA4 connectors are used by Sound Devices
for DC power connections to the 833 mixer-recorder. TA4 is also used
for audio connections from lavalier microphones to some wireless
transmitters. TA5 connectors are used for the 833 headset input. TA6
connectors are presently not used by Sound Devices though they are
used for audio connections by other manufacturers.
Take
A recorded take is an individual recorded le (or les when recording
monophonic WAV les) generated by a recorder. Take numbers are
auto-incrementing. Take numbers are added to the end of the le
name.
Take list
Separate from a le list, a take list consolidates related les such
as a group of monophonic WAV les generated by a single take and
presents them as a single take.
Test tone
See tone oscillator.
Timecode
A numerical clock value expressed in hours:minutes:seconds:frames,
i.e. 04:59:39:05, used to synchronize cameras, video decks,
and audio recorders. Timecode requires clocks on devices to be
synchronized, either through a wired or wireless connection between
devices, or through a process called “jam sync” where each device,
which requires a high-precision clock, runs independently after their
clocks are synchronized.
Timecode mode
Sound Devices recorders offer multiple timecode modes. Different
modes correspond to different timecode workows. Common modes
available in Sound Devices recorders include:
record run - timecode advances only when recording is engaged
free run - timecode run continuously, typically with the start of
production being at 0 hour
24 hour - similar to free run except the start time corresponds to
time-of-day
ext TC - the recorder applies the value of an external timecode
source.
Tone oscillator
A sound generator producing a sine wave tone at a given frequency at
a given output level. With its known output level tone oscillators are
helpful to set gain structure between audio equipment.
Track
A single recorded audio signal. Common recorded tracks are the main
left/right master audio bus and isolated (iso) channel recordings. Iso
tracks are typically identied by the channel of the same number, e.g.
channel 1 is sent to track 1, channel 2 is sent to track 2, etc.
Track arm
Tracks that are active and ready for recording are said to be “armed”.
When recording begins all armed tracks begin recording. Depending
on the production is may be advantageous to arm and disarm tracks,
especially to disarm unused tracks.
Track name
Individual tracks of a multi-track recording can be named to indicate
microphone type or character name.
Trim
Also dened in mixers as “gain”, the trim adjustment is the rst
stage of gain of a microphone or line level input. Typical microphone
trim values range from 10 dB to 50 dB, depending on microphone
sensitivity and volume of the sound source.
User bits
Static, numeric data that is available as part of a timecode signal.
User bits are often used to indicate the date of a le. User bits are
four sets of two-digit hexadecimal numbers from 00 to ff.
WAV File
A universal, well-supported le type for sound le recordings. WAV les
can contain one or more (up to 65,535) tracks of PCM audio data at
any sampling rate and bit depth. A standard WAV le is limited to a
maximum le size of 4 GB. Sound Devices uses the .WAV extension
for recorded les, including for les with Broadcast WAV metadata
and WAV RF64 les.
WAV RF64
An extension of the WAV le type that supports le sizes larger than 4
GB. When recording high track count, high sampling rate polyphonic
WAV les, the 4 GB size limitation of WAV can be reached quickly.
RF64 les larger than 4 GB require recording to a volume type than
can support le sizes larger than 4 GB.
Word clock
A reference signal used to synchronize the sampling rate of multiple
digital devices.
