Signal Presence and Peak Indicator
The signal presence and peak indicators show audio activity before input-to-track routing. In-
put signal presence LED’s illuminate when a –50 dBFS or greater signal is present. Input signal peak
LEDs illuminate when signal levels reach –3 dBFS or greater.
Input Delay
A digital delay is selectable on each channel of the 702. Delay time per input is selectable in tenths of
a millisecond (0.1 msec) steps. The Rotary Switch and menu arrows are accelerated. The more you
press or spin, the faster the time setting will increase or decrease. Delay is not set until the Rotary
Switch is pressed or or the check mark is selected. The amount of delay available is dependent on the
sampling frequency in use.
Sample Frequency
Maximum Amount of Delay Available (per input)
32, 44.1, 47.952, 48, 48.048 kHz
30 mS
88.2, 96, 96.096 kHz
15 mS
176.4, 192 kHz
7.5 mS
Input delay can be useful for time aligning input signals from differing sources. For example, digital
wireless mics that have a processing delay in their outputs. In addition, all digital conversion stages
have delay.
Input-to-Track Routing
The 702 uses a flexible routing scheme to assign inputs and tracks for recording. The input matrix
allows any input to be routed to any recording track. Multiple inputs can be routed to a single track
to create mono-mixed recordings.
The 2-by-2 blue LED matrix makes it easy to view the set routing. A solid blue LED indicates an
input is assigned to a record track.
inputs can be routed
to tracks in any of
