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

sixteen possible

combinations

Pressing the

INPUT key brings up the following menu.

Routing

Hold down the STOP button then press the INPUT button

to cycle through the four preset

input-to-track routing combinations. These presets are factory set and cannot be changed. The last

three preset selections are

CUSTOM ROUTE options. Press the EDIT soft button to enter the custom rout-

ing menu. Custom routing allows any input to be assigned to any record track. In the menu, high-
