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.
