Glossary
| Term | Meaning |
|---|---|
| ADC | Analogue-to-digital converter. Converts an analogue input signal into digital audio for the computer. |
| ARC | Audient Resource Centre. The Audient account and product-registration service used to access software and product resources. |
| Artist Mix | EVO 8's secondary software-monitor mix for outputs 3+4 / headphone output 2. It can have a different balance from the main mix. |
| ASIO | Audio Stream Input/Output. The Windows low-latency audio-driver system used by recording applications with EVO 8. |
| 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. |
| Control Knob | EVO 8's central rotary control. Its function changes according to the selected input or output group. |
| DAC | Digital-to-analogue converter. Converts digital audio from the computer into analogue signals for the speaker and headphone outputs. |
| DAW | Digital Audio Workstation. Software used to record, edit, mix or play back audio. |
| 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 | The high-impedance input used to connect instruments such as electric guitar or bass directly to EVO 8. Connecting the front instrument input overrides rear input 1. |
| Gain | The amount of amplification applied to an input signal before conversion to digital audio. |
| JFET | Junction Field Effect Transistor. EVO 8 uses a JFET instrument-input stage 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 recording or streaming software as a stereo input. On EVO 8 the loopback signal appears on input channels 5+6. |
| Loopback 1+2 | EVO 8's dedicated loopback playback pair, corresponding to computer outputs 5+6. The hyphenated form is retained where it matches the EVO application label. |
| Main Mix | The primary monitor mix in the EVO Mixer, normally used for outputs 1+2 / headphone output 1. |
| 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 8 supports 44.1, 48, 88.2 and 96 kHz sample rates. |
| Smartgain | EVO's automatic gain-setting feature. It analyses the selected input signals while you perform and sets their input gains automatically. EVO 8 can set multiple inputs during one Smartgain process. |
| SmartMuting | EVO 8 behaviour that automatically mutes the matching speaker-output pair when headphones are connected to that output group. |
| Stereo link | Links inputs 1+2 or 3+4 so the pair can be controlled and displayed together for a stereo source. |
| 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. |
| USB bus power | Power supplied to EVO 8 through its USB connection, so a separate power supply is not normally required. The available USB current affects simultaneous phantom-power capacity. |
| XLR | Three-pin balanced connector used for microphone signals. |
