Biamp Tesira & Q-SYS DSP Concepts: Commissioning, Tuning & Verification
Learning objectives
- Describe Biamp Tesira and Q-SYS DSP concepts at a high level.
- Outline a safe commissioning workflow.
- Tune a room systematically.
- Verify the result with test signals and a call.
Vocabulary
- Biamp Tesira
- A DSP platform with fixed and configurable audio blocks.
- Q-SYS
- A combined DSP/control platform with a software design environment.
- Pink noise
- A test signal with equal energy per octave; used for tuning.
- RTA / analyzer
- A real-time spectrum analyzer used while tuning.
Lesson content
Two DSP ecosystems dominate commercial AV: Biamp Tesira and Q-SYS. Both give you audio blocks (mixers, AEC, EQ, dynamics) you wire in software and load to the DSP. The concepts transfer; the software differs.
Ecosystem concepts
- Biamp Tesira — server/processor with a design tool; drag audio blocks and wires; supports AEC, automixing, routing.
- Q-SYS — DSP and control in one design environment; same audio blocks plus UCI and scripting.
Safe commissioning workflow
- 1Confirm all gains at unity to start; nothing clipped.
- 2Set preamp gains for each mic with a talker.
- 3Route and enable AEC per mic with the correct reference.
- 4Configure the automixer.
- 5Apply HPF and gentle EQ using pink noise and an analyzer.
- 6Set a limiter on outputs.
- 7Align speaker delays by ear from a representative seat.
Verification
- Confirm no clipping anywhere in the chain.
- Confirm the far end hears no echo (test call).
- Confirm local talkers are clear from several seats.
- Confirm content audio (share) reaches the far end and the room.

Worked example
Commissioning the conference room: preamps set with a talker, AEC enabled per mic with the far-end reference, automixer tuned, HPF + light EQ set with pink noise, limiter on outputs, delays aligned by ear. A test call confirms no echo and clear talkers from six seats.
Implementation checklist
- ✓Preamps set with a real talker.
- ✓AEC per mic with correct reference.
- ✓HPF + gentle EQ via pink noise/analyzer.
- ✓Limiter on outputs; delays aligned.
- ✓Verified by test call and seat walk.
Downloadable study guide
01. Tesira and Q-SYS both provide audio blocks wired in software; concepts transfer. 02. Commissioning: gains → AEC → automix → EQ → limiter → delay → verify. 03. Verify with pink noise/analyzer, a test call, and a seat walk. 04. Confirm no clipping, no echo, clear talkers, content reaches both ends.
