Glossary
| Term | Meaning |
|---|---|
| ADC | Analogue-to-digital converter. Converts an analogue input signal into digital audio. |
| ADAT | A multichannel optical digital-audio format. EVO 16 can use its optical ports for ADAT expansion. |
| ARC | Audient Resource Centre. The Audient account and product-registration service used to access software and product resources. |
| ASIO | Audio Stream Input/Output. The Windows low-latency audio-driver system used by recording applications with EVO 16. |
| BNC | A locking coaxial connector. EVO 16 provides a BNC word-clock output for synchronising compatible digital equipment. |
| Buffer size | The amount of audio held by the computer's audio driver while processing. Smaller buffers reduce software-monitoring latency but require more processing performance. |
| Clock source | The digital timing reference used by EVO 16. A digital system must have one master clock, with other devices synchronised to it. |
| Cue Mix | One of four independent EVO Mixer monitor mixes, Cue A-D. Cue Mixes can be routed to analogue, headphone or digital outputs and can also be used as loopback sources. |
| DAC | Digital-to-analogue converter. Converts digital audio into analogue signals for the line and headphone outputs. |
| DAW | Digital Audio Workstation. Software used to record, edit, mix or play back audio. |
| DAW THRU | EVO 16 output-routing mode that sends a DAW playback channel directly to the selected hardware output rather than routing it through a software-monitor mix. |
| dB | Decibel. A unit used to express changes or ratios in audio level. |
| dBFS | Decibels relative to digital full scale. 0 dBFS is the maximum level in a digital audio system. |
| dBu | A voltage-referenced audio level where 0 dBu equals 0.775 Vrms. |
| DI / instrument input | A high-impedance input for instruments such as electric guitar or bass. EVO 16 provides front-panel instrument connections for analogue inputs 1 and 2. |
| Function button | EVO 16's programmable front-panel F button. It can be assigned to functions including Dim, Alt Speakers, Talkback or Mono. |
| Gain | The amount of amplification applied to an input signal before conversion to digital audio. |
| JFET | Junction Field Effect Transistor. EVO 16 uses JFET instrument-input stages for high-impedance instruments. |
| Latency | The delay between an audio signal entering or being generated by the system and being heard at an output. |
| Loopback | Internal routing that presents computer playback or an EVO Mixer mix to another application as a stereo input. On EVO 16, loopback appears on input channels 23+24. |
| Main Mix | The primary monitor mix in the EVO Mixer. It can be routed to the main line outputs, headphone outputs or other available outputs. |
| Motion UI | EVO 16's front-panel display system, used for metering, parameter feedback, status information and hardware settings. |
| Optical S/PDIF | Two-channel S/PDIF digital audio carried over an optical TOSLINK connection. EVO 16 optical ports can be configured for ADAT or optical S/PDIF. |
| Phantom power / 48V | DC power sent through an XLR microphone connection for microphones that require it, typically condenser microphones. Check the microphone documentation before enabling it. |
| Sample rate | The number of digital audio samples taken each second. EVO 16 supports sample rates up to 96 kHz. |
| Smartgain | EVO's automatic gain-setting feature. EVO 16 can analyse and set the gain for multiple analogue inputs during one Smartgain process. |
| SMUX | A method used by ADAT to carry higher sample rates by spreading each channel across additional optical bandwidth. At 88.2 or 96 kHz, each EVO 16 ADAT optical connection carries four channels. |
| Standalone state | A mixer and routing configuration stored in EVO 16 for use when the interface is powered without a host computer. |
| Stereo link | Links an adjacent analogue-input pair so it can be controlled as a stereo source. EVO 16 supports pairs 1+2, 3+4, 5+6 and 7+8. |
| Talkback | A communication signal routed to the EVO 16 Cue Mixes so the engineer can speak to performers without feeding the Main Mix. |
| TOSLINK | The optical connector and cable type used for EVO 16's ADAT and optical S/PDIF connections. |
| TRS | Tip-Ring-Sleeve 1/4-inch jack connection. Commonly used for balanced line-level audio and stereo headphones. |
| TS | Tip-Sleeve 1/4-inch jack connection. Commonly used for unbalanced instrument connections. |
| Word clock | A digital timing signal used to synchronise audio devices. EVO 16 provides a BNC word-clock output but does not provide a BNC word-clock input. |
| XLR | Three-pin balanced connector used for microphone signals. |
