Application Notes
Bus Connections
BUS A LOW PASS X-OVER: Subwoofer crossover can be set to 80Hz or 120 Hz. High Pass x-over will impact the Left and Right BUS A channels as well.
Powering a Passive Subwoofer: Use RCA from subwoofer output to an unused discrete line input in BRIDGE mode.
Note: Setting the X-OVER to 80Hz or 120Hz will crossover the signal for any zone output using BUS A (80Hz and above, or 120Hz and above).
Connect source audio cables to Bus A, Bus B, or Direct, making sure to adjust DIP switch to appropriate selection for each Zone Output.
Sense Switch for Power Selection
- Switch Set to "OFF": Amp is always powered on, ready to play audio.
- Switch Set to "VOLTAGE": Amp will power on with 12V DC applied. Use the output to pass through to other amps.
- Switch Set to "AUDIO": Amplifier will power on with audio signal after 4-6 seconds, and off with a loss of audio signal after 15 minutes.
Zone Input Connections
- Use RCA connections from discrete source to play to associated zone (discrete inputs are always active).
- Use DIP switch if using Bus A, Bus B, or to bridge the speaker output.
- Note the alternating Left or Right Discrete input for bridged mode outputs.
- Zone Level Control: Adjust in small increments to correct output gain as needed.
Bus Inputs and DIP Switches
DIP Switch selections can include one or both BUS inputs, and/or BRIDGE. When more than one BUS input is selected on the DIP switch, the audio signals will be mixed and all will be played back in that zone. This can be useful when one BUS includes paging or a doorbell signal.
Speaker Connections
Attach speaker wire (up to 12 gauge) with included speaker block connectors for each zone.
Wiring for Bridge Mode: Use Left Positive and Right Negative connections.
Accepts speaker wire, up to 12 gauge. Note polarity when connecting.
Note: Do not combine negative terminals. The amp is not common ground type architecture.
LED Status Indicators
Front Panel System Status Indicator
- White: Amp has power and is in Standby mode
- Blue: Amp has power and is Active
- Red: Amp is in protect mode. Power cycle amplifier to reset, check all connections.
Front Panel Zone Indicators
- White: Amp channel is on, no audio present
- Blue: Amp channel is on, audio present
- Red: Amp channel in protect mode. Power cycle amplifier to reset, check all connections.
- Yellow: Clipping amplifier output.
Rear Panel Clip Indicators
- Red: Zone Signal is too high, clipping amp output. Resolve by lowering source input signal or volume.
Front Panel
The front panel features status indicators.
- 1. System Status Indicator: Provides overall amplifier status.
- 2. Zone Status Indicator: Indicates the status for each individual audio zone.
IMPORTANT: DO NOT PLUG THE POWER CORD INTO THE OUTLET UNTIL ALL SYSTEM CONNECTIONS HAVE BEEN MADE.
Rear Panel (Sonance 8-50)
The rear panel of the Sonance 8-50 Multi-Channel Amplifier includes the following connections and controls:
- 3. AC Power Socket: For connecting the IEC power cord.
- 4. AC Power Switch: Main power switch.
- 5. Sense Switch: Selects power-on mode (OFF, VOLTAGE, AUDIO).
- 6. Voltage Trigger Connector: For 12V DC trigger input.
- 7. Bus A Input / Thru: Input for audio signal Bus A, with a pass-through option.
- 8. Crossover Switch (Bus A): Sets the low-pass crossover frequency for Bus A (80Hz or 120Hz).
- 9. Sub Out (Bus A): Subwoofer output for Bus A.
- 10. Bus B Input / Thru: Input for audio signal Bus B, with a pass-through option.
- 11. Zone Configuration DIP Switch: Used to select Bus A, Bus B, or BRIDGE mode for each zone.
- 12. Zone Level Control: Adjusts the output gain for each zone.
- 13. Zone Speaker Outputs: Connects speakers for each zone.
- 14. Zone Local Inputs: Discrete RCA inputs for each zone.
- 15. Zone Clip Indicator: Indicates signal clipping for each zone.
Rear Panel (Sonance 16-50)
The rear panel of the Sonance 16-50 Multi-Channel Amplifier includes similar connections and controls as the 8-50 model, supporting more zones.
- AC Power Socket
- AC Power Switch
- Sense Switch
- Voltage Trigger Connector
- Bus A Input / Thru
- Crossover Switch (Bus A)
- Sub Out (Bus A)
- Bus B Input / Thru
- Zone Configuration DIP Switch
- Zone Level Control
- Zone Speaker Outputs
- Zone Local Inputs
- Zone Clip Indicator
(Specific numbering for the 16-50 rear panel is not explicitly detailed in the provided text, but the component types are consistent with the 8-50.)
