into the external processor, then back into the EUREKA. The final, processed
signal will be available at the EUREKA output connector. The Send and Return
signal will be inserted after the microphone preamplifier, before the compressor.
3.3 192K/24-BIT DIGITAL OUTPUT CARD (OPTIONAL)
A 192K/24-BIT Digital Output Card is available as an option for the PreSonus
EUREKA. It has AES/EBU and SPDIF output connectors, as well as, an
auxiliary ¼” TRS analog Line input connector. The card has a selectable
sample rate of 192kHz, 96kHz, 48kHz and 44.1kHz. The A/D converters
provide psycho-acoustic dithering for improved BIT resolution when
conversion from 24-BIT to 16-BIT sampling is necessary. The ¼” TRS Line
input will provide the benefit of allowing two EUREKA‘s to share one Digital
Output Card and in so doing, share both sides of the A/D converter.
