Focusrite OctoPre Full Spec ADC

The full spec optional ADC for OctoPre offer three output formats; AES/EBU, S/PDIF and a simultaneous ADAT output.

The converters are 24-bit and 128x over-sampled, handling sample rates of up to 96 kHz, but can dither down to 20 or 16 bit. All frequency settings and bit rates can be altered from the front fascia, with an ADC lock LED to show when word clock is synchronised.

An external Wordclock input is also provided (BNC connector). The AES/EBU or S/PDIF format outputs can run simultaneously with the lightpipe outputs, giving up to 16 channels of digital output for all sample rates.

Specifications

• Dynamic Range = 110dB
• Clock jitter = 250 picoseconds
• Clock jitter when synced to an external clock = 1 nanosecond
• THD+N AMPL = -109dBFS 'A' weighted
