2. Analog Audio Outputs

These are balanced, 1/4-inch TRS jacks for

analog audio output connections. The

882/20 I/O analog outputs feature 20-bit

digital-to-analog converters.

All eight output channels are continuously

active. Output operating levels are switch-

able between +4 dBu and –10 dBV opera-

tion. Unbalanced connections are sup-

ported with the use of standard 1/4-inch

mono phone plugs.

The 882/20 I/O analog outputs are factory

calibrated at a –14 dB nominal level, refer-

enced to a full code signal. This means that

at the nominal reference output level (ei-

ther +4 dBu or –10 dBV), you have 14 dB

of headroom before clipping.

3. Slave Clock In/Out

The Slave Clock Out jack is a standard BNC

type connector that outputs a 256x audio

sample rate master Super Clock signal for

slaving and synchronizing multiple

Digidesign Interfaces and synchronization

peripherals together.

The Slave Clock In jack is a standard BNC

type connector designed to receive a Slave

Clock Out signal from another Digidesign

Interface, a Universal Slave Driver

™

Slave Driver

, or SMPTE Slave Driver

synchronizing multiple Digidesign Inter-

faces and synchronization peripherals to-

gether.

882/20 I/O

When the 882/20 I/O Sync Mode is set to

Internal, connecting a valid Slave Clock

Out signal to this port will cause the

882/20 I/O to automatically switch to

Slave mode. When the 882/20 I/O is the

master interface or the first interface in a

chain, Digital sync mode overrides the

Slave Clock input, and an incoming Slave

Clock Out signal will not switch the

882/20 to Slave mode.

Because crucial timing data is passed over

these ports, you should use high-quality,

75-ohm RG-59 cables for making connec-

tions, and keep total cable length to less

than 3 meters between interfaces.

4. S/PDIF Digital Input/Output

The Sony Phillips Digital Interface Format

(S/PDIF) is used in many professional and

consumer CD players and DAT recorders.

The 882/20 I/O S/PDIF jacks are unbal-

anced, two-conductor, phono (RCA) jacks.

Because input channels 1–2 of the

882/20 I/O are software selectable between

analog or digital format, input to these two

digital channels is disabled when analog

input is chosen in the Hardware Setup dia-

active on the S/PDIF output jack, even if

the 882/20 I/O input selector is set to Ana-

™

, Video

™

for

RF interference, use 75-ohm coaxial cable

for S/PDIF transfers and do not exceed a ca-

ble length of 10 meters.
