How audio is routed

Understanding the path makes the four audio pages and Output Routing fall into place.

A zone selects one source. That source can be an analogue input, a digital input, a mix bus, or the generator. Mix buses are optional — use them only when a zone should hear a blend of several inputs.

Analogue 1–4 ──┬──────────────────► Zone 1–4 ──► Speaker Output 1–4
               │                        ▲
Digital 1–4  ──┼──────────────────►     │
               │                        │
               └─► Mix Bus 1–4 ─────────┘
                   sends: Analogue 1–4 + Digital 1–4

Generator ────────────────────────► Zone 1–4

Analogue / Digital / Mix / Zone ──► Expansion Output 1–4

The amplifier DSP runs at 96 kHz.

Inputs

Eight sources:

  • Analogue 1–4 — rear analogue inputs. Each has trim, sensitivity, and five bands of parametric EQ.
  • Digital 1–4 — expansion / digital inputs. Each has trim only.

Mix buses

Four mix buses. Each bus has eight send levels — Analogue 1–4 then Digital 1–4. Use a mix when a zone should hear a blend of several inputs. Turn unused sends down to −80 dB (Mute) or they will still contribute.

Zones

Four zones (the 2RU front panel lists them as ZONE 1–4). A zone selects one source:

  • Any analogue input
  • Any digital input
  • Any mix bus
  • The signal generator

and applies a zone level (−80 to +6 dB).

Factory default: Zone n listens to Analogue n at 0 dB.

Speaker outputs

Each amplifier channel listens to one zone (1–4). On the output you set level, mute, polarity, delay, crossover, a speaker preset, and ten bands of user EQ.

Factory default: Output n listens to Zone n, unmuted, 0 dB, no delay, no crossover, FLAT preset.

Expansion outputs

The four expansion outputs (for example a Dante or other expansion card) are a separate router. Each can take an analogue input, digital input, mix bus, or zone. They are configured on Settings → Output Routing, not on the Speaker Outputs page.

Factory default: Expansion n follows Analogue n.

What “live” means

Audio edits are sent immediately and written to flash in the background. If two people (or the front panel and a browser) change the same control, the last write wins and all open browsers are updated.
