Model and application
- System
- Syva, passive
- Horizontal
- 140° nominal
- Vertical
- +5° / −21° nominal
- Processing
- LA controller + matching preset
- Connection
- speakON / terminal / AutoConnect
Syva, Syva Low and Syva Sub are distinct elements. Coverage figures do not determine a venue capacity.
Connections and required equipment
The enclosure receives amplified speaker audio. AutoConnect carries the intended system connection when stacked in the documented configuration; it is not a line-level input.
Prepare the system
- Identify controller, library, preset and actual arrangement.
- Compare every cable and output assignment with the matching manual diagram.
- Use the approved design and measure coverage before opening the venue.
Questions and troubleshooting
Why is the column silent?
Trace the controller output and speaker path.
- Check controller input, mute, preset and output indication.
- With outputs safely isolated, verify the correct cable and input arrangement; never add a parallel feed to AutoConnect.
- If input is present but output is muted/protected, resolve that controller condition with the responsible technician. After the approved correction, verify the intended speaker path at controlled level; persistent silence with a validated path requires service, not a second feed.
Which preset applies with a low-frequency element?
Match coupled hybrid or separate processing to the documented layout.
- Record element labels, physical placement and connection method.
- Compare the exact preset guide and controller library; do not copy a forum channel layout.
- If the loaded preset does not match the documented coupled/separate layout, stop before increasing level. Have the system owner reconcile the exact configuration and verify column and low-frequency sections separately, then together; unresolved mapping requires manufacturer support.
Why is coverage uneven?
Directivity and room geometry both matter.
- Compare audience position with the design and column orientation.
- Measure the affected area before changing level, EQ or delay.
- If the difference is limited to an audience area, document that location and request design/measurement review rather than global EQ. Verify the same reference at the same locations after an agreed correction; mechanical changes belong with the responsible installer.
Choose the next check
| Observation | Next check | What to record |
|---|---|---|
| No output | Controller and speaker path | Preset, mute, cable |
| Grouped controls | Hybrid or separate preset | Library, version, arrangement |
| Uneven coverage | Orientation and design | Measurement location |
Precautions
- Do not use Syva speakON or terminals while AutoConnect is in use.
- Use only the documented mechanical configuration and qualified installation.
- Do not derive rigging loads, amplifier counts or delay values from user reports.
