Sound Devices 664 - Manual (Page 19)

Each connector carries two channels of digital audio. Alternate channels of digital audio sent to In-
put 1 or Input 6 are available on adjacent inputs, according to the following table.
AES Input Channel: Available to 664 Input:
XLR-3F Input 1, Left Channel Input 1
XLR-3F Input 1, Right Channel Input 2 (Available when Input 1 source is set to AES)
XLR-3F Input 6, Left Channel Input 5 (Available when Input 6 source is set to AES)
XLR-3F Input 6, Right Channel Input 6
The 664’s digital inputs are sample rate converted to the internal recorder’s sample rate. To sync the
sample rate of the 664’s internal recorder to external digital audio devices, see Sampling Rate .
Things to consider when using AES digital inputs:
• When using an unbalanced AES3 (SPDIF) input, the other available digital input should not be
used with an AES42 microphone.
• Signal from digital inputs is not available on direct outputs.
12 Channel Mode
Direct outputs 1 to 6 can be used as line inputs in 12 Channel Mode. When Setup Menu option
INPUTS > Input Mode is set to 12 Channel, direct outputs 1 to 6 are changed to line inputs 7 to 12,
respectively. Each input is routed to its own ISO track and can be recorded. Each 7-12 input can be
switched to be a direct output for its respective 1-6 input.
When switching to 12 Channel Mode, Meter Views are not changed automatically, so inputs 7-12
may not be visible on any Meter View
( See Meter Views ). To automatically switch Meter Views while
switching between 6 Channel and 12 Channel Mode, it is recommended to save custom Setup Files
with the desired Input Mode and Meter Views. See Storing and Recalling Settings
The function of the Input Selector switches is altered in 12 Channel Mode: Slide the switch to the
right to PFL and access the Input Settings screen for inputs 7-12, and slide the Input Selector switch
left to PFL and access the Input Settings screen for inputs 1-6. The Input Settings screen for inputs
7-12 is slightly different than the Input Settings screens for inputs 1-6. HPF, Trim, and Fader values
are adjusted using the Select Encoder:
