Sound Devices 664 - Manual (Page 28)

Output Setup and Control
The 664 features a host of analog and digital outputs to accommodate for complex, multi-camera
setups. The 664 has 2 stereo output busses: The Master Bus (LR), and the Aux Bus (X1/X2).
Master and Aux Outputs
There are 4 pairs of balanced analog output connections for the Master Bus (XLR-3M, TA3, and 2
Hirose 10-pin), and one pair of balanced analog output for the Aux Bus (TA3). Additionally, there are
two stereo unbalanced outputs for the Master Bus (TA3 and 3.5mm Tape Outputs).
The XLR-3M and both Hirose 10-pin outputs are transformer-balanced, each driven from their
own transformer windings for excellent isolation. Each output can be independently set to Line
(+4 dBu nominal), -10, or Mic level (40 dB of attenuation versus Line) from the Setup Menu section
OUTPUTS. The master outputs are capable of driving long cable runs.
XLR-3M
By default the XLR-3M outputs send a balanced analog signal. These connections can be indepen-
dently configured to send AES3 signal. see AES Digital Outputs for details. When set to analog output,
the L and R XLR-3M connections always carry the Left and Right Master Bus program.
TA3 (Master L, R, X1, and X2)
The TA3 outputs send a balanced analog signal. The X1 and X2 TA3 connections always carry X1
and X2 Aux bus program. The L and R TA3 connections always carry the Left and Right Master Bus
program.
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 bal-
anced analog signal. Each of the balanced outputs on the 10-pin A connections can be independently
configured to send AES3 signal. see AES Digital Outputs for details.
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
outputs are pre-fade and line level. The direct outputs can be set to post-fade from the Set-
up 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.
Tape Output
The 664 includes two unbalanced tape level outputs, a TA3 connector and a 3.5 mm jack. These two
connectors are resistively in parallel and are isolated from the balanced outputs.
