ESI-32 Operation Manual
The S/PDIF port on the rear panel of the ESI-32 accepts an optional
S/PDIF digital interface card. The digital input and output jacks allow
you to transfer digital audio back and forth with other devices equipped
with S/PDIF digital I/O.
The digital input allows you to sample directly from a DAT recorder or
other digital device. The digital output reflects the data at the main
outputs of the ESI-32. This can be used to go directly to a DAT recorder
or to a digital mixing console.
The digital interface is straightforward to use. Three additional choices
(S/PDIF 32K, S/PDIF 44.1K and S/PDIF 48K) will appear in the Sam-
pling Setup menu if you have the digital I/O board installed. These three
additional options select the digital interface for sampling instead of the
analog inputs. Connect the digital output of the ESI-32 to a digital input
on another device with S/PDIF digital I/O
When the digital interface card is installed, both the analog and digital
outputs are simultaneously available. The Main Output Format option
(Master/Global, Special, 5) allows you to select either analog or digital
outputs and adjusts the ESI-32 output level for optimum performance.
When using the digital outputs, bear in mind that the Headroom Adjust-
ment (Master/Global, Special, 4), the front panel Master Volume control
and the VCA Level control (Dynamic Processing, 2) all affect the level on
the digital audio output. These controls should be adjusted when
transferring digital audio to optimize the signal level. For a single
channel output, the maximum output level of the ESI-32 will be -6 dB.
