Hirose 10-pin

Each Hirose 10-pin connection has a balanced pair of outputs that carry the Left and Right Master bus
program. By default, each of the balanced outputs on the Hirose 10-pin connections sends a balanced
analog signal. Each of the balanced outputs on the 10-pin A connections can be independantly confi g-
ured to send AES3 signal.
Each Hirose 10-pin also includes an unbalanced stereo return input for headphone monitoring. The
Sound Devices XL-10 Breakout Cable is an available accessory that provides easy access to the bal-
anced outputs and stereo returns of the 10-pin Hirose connections.

Direct Outputs

Inputs 1-6 have corresponding direct outputs on balanced TA3 connections. By default, these out-
puts are pre-fade and line level. The direct outputs can be set to post-fade from the Setup Menu item
OUTPUTS > Direct Out Pre/Post. The direct outputs can be set to Line (+4 dBu nominal), -10, or Mic
level (40 dB of attenuation versus Line) from the Setup Menu item OUTPUTS > Direct Out Levels.
AES digital input signals are not available on direct outputs.

Master and Aux Bus Level

The output gain of the Master Bus and the Aux Bus is adjustable from Off , -30 to 0dB. To adjust output
gain:
1. From the Main Screen, turn the Select Encoder to highlight the output(s) to be att enuated.
2. Push the Select Encoder. The output level of the highlighted track will be displayed in the
lower right-hand corner of the LCD. If no adjustment is made before 3 seconds, the selection will
cancel. This is to avoid accidental adjustments.
3. Turn the Select Encoder to adjust the gain.
Outputs that are linked (from Setup Menu item OUTPUTS > Linking) will be shown as a connected
box on the Main Screen and their gain will be adjusted simultaneously.

AES Digital Outputs

There is a total of 8 available channels of digital output on 4 connections. Each of the XLR or 10-
pin A outputs can be confi gured to output AES3 digital signals from the Setup Menu options
OUTPUTS > XLR-R Out, OUTPUTS > XLR-L Out, and OUTPUTS > 10-pin A Out.
Any track can be routed to any AES output in any combination. The AES output routing can be edited
from the Setup Menu item OUTPUTS > AES Output Routing. This interface consists of a matrix in
which the columns are tracks and the rows are the numbered AES outputs. The blue boxes indicate
routed tracks and the black boxes indicate unrouted tracks. Turn the Select Encoder to move the
orange highlighter vertically and turn the Headphone Encoder to move the highlighter horizontally.
Push either the Select Encoder or the Headphone encoder to toggle the routing status of the highlight-
ed track.
see AES Digital Outputs for details.
