DIGITAL OUTPUT [ AES ]

A high quality Analogue to Digital converter is available as an option. It performs the digital conversion of 8
audio channels with a resolution of 24 bits. These 8-channel audio are grouped in pairs; four AES-31,
transformers balanced digital outputs are available on the Sub-D 25 pin connector [DIGITAL OUT] on the rear
panel. Any external devices providing with AES digital input can be connected such as digital cameras,
external audio recorder or a computer via a digital audio interface, etc.

By default these 8 channels are internally wired to the direct outputs of the six input channels and to the main
out of groups 1 & 2. On request, the main out of groups 3 & 4 can be wired instead of channels 5 & 6.
The direct out of the channels are taken either Pre-Eq, or Post-Eq or Post-fader. Selection is made by an
internal soldering jumper on the input module.

The four AES outputs are configured as follows:

• AES#1 : direct outputs of channels 1 & 2
• AES#2 : direct outputs of channels 3 & 4
• AES#3 : direct outputs of channels 5 & 6 ( or Master 3 & 4 )
• AES#4 : Master outputs 1 & 2


The digital audio level is set at factory and depends on the nominal output level, this means of the analogue
output level corresponding to a reading of "0 Peak" on the modulometre

- the digital level is -18dBFS if the SX-ES64 is set for a nominal output of +6dBu when reading "0 Peak"
- the digital level is -20dBFS if the SX-ES64 is set for a nominal output of +4dBu when reading "0 Peak"

NOTE:

The selection of the direct output source for the ADC is independent from the one that feed
the analogue direct channel output.

Sampling frequencies [ 96 EXT 48 ]

By default the SX-ES64 internal clock provides with two sampling frequencies; either 48kHz or 96kHz
selectable with the switch [96 EXT 48].

While in [EXT] position, the A/D Converter will automatically lock on any external wordclock connected to
"WCKL IN" connector and having a frequency between 22kHz to 200kHz.

If the switch is set to [EXT] and no external word clock signal is detected, the A/D converter is then turned off,
which saves on batteries if the converter is not used.

The WCKL OUT connector provides with a re-clocked wordclock signal at the same sampling frequency as
the A/D Converter.

NOTE:

- by default, the ADC offers the choice of 48kHz and 96kHz at 24bits and outputs an AES-31
signal. Internal jumpers offer following choices:
- FS at 192kHz/24bits instead of 48kHz (the position 96kHz remain unchanged)
- 48kHz at 16 bits instead of 24bits ( the 96kHz position remain unchanged at 24 bits)

WARNING:

Any modification of the default settings must be done by a qualified technician.
