AD/DA conversion​

Analogue-to-digital and digital-to-analogue conversion. EVO SP8 can convert analogue inputs to digital audio for ADAT transmission and convert incoming digital audio for its analogue line outputs.

ADAT​

The digital-audio format used by EVO SP8's optical inputs and outputs. At 44.1 and 48 kHz, one optical connection carries eight channels; at 88.2 and 96 kHz, each optical connection carries four.

ADAT SMUX​

The ADAT mode used by EVO SP8 at 88.2 and 96 kHz. Two optical connections are required to use all eight channels at these sample rates.

Clocking​

The process of synchronising digitally connected audio devices to the same timing reference.

Clock Source​

The setting that determines where EVO SP8 receives its digital clock: Internal, Digital or Word Clock.

EVO Expanded System​

A system combining EVO 16 with one or two EVO SP8 preamp expanders. With EVO 16 and two SP8 units, Smartgain can operate across up to 24 input channels.

Primary clock​

The term used in EVO SP8 V2.2 for the device that provides the clock signal to the other digital devices in a system. This online manual generally calls it the clock source.

Replica clock​

The term used in EVO SP8 V2.2 for a device that synchronises to the primary clock. This online manual generally describes it as a device synchronised to the clock source.

Sample rate​

The number of digital-audio samples taken per second. EVO SP8 supports 44.1, 48, 88.2 and 96 kHz.

Smartgain​

EVO's automatic input-gain setting feature. Smartgain analyses selected input signals and sets their gain automatically.

A function that pairs adjacent EVO SP8 inputs so their gain can be adjusted together. Available pairs are 1 + 2, 3 + 4, 5 + 6 and 7 + 8.

Word clock​

A dedicated timing signal used to synchronise digital audio devices. EVO SP8 can receive word clock through its BNC Word Clock Input.

Word Clock Termination​

The setting used when EVO SP8 is part of a BNC word-clock chain. Set termination On when EVO SP8 is the final device in the chain and Off when the clock connection continues from that unit to another device.
