AP-12V-TRIGGER-OUT

Description

Add a trigger output to your audio equipment

The AP-12V-TRIGGER-OUT provides a trigger output for DIY audio equipment or a custom controller. Use it to send an on/off control signal to compatible equipment with a trigger input.

The board uses a supply connection to drive the trigger output and a separate logic signal to activate it. This lets your project’s control circuit determine when downstream equipment should operate.

Key features

• Trigger output interface for integration into your own audio equipment.
• Output current limited to 100 mA.
• Short-circuit-protected output.
• Separate supply and on/off control connections.

Electrical requirements

• Supply voltage: 8–15 V DC to drive the trigger output.
• Activation signal: 3–12 V logic to enable the output.
• Output current limit: 100 mA.

Use the connection diagram in the product gallery to identify the supply, ON/OFF control and ground connections. Select a supply that is appropriate for the trigger input of the equipment you intend to control.

Before connecting

• Check the receiving device’s trigger voltage range, polarity and cable requirements.
• Check the combined current demand if you plan to connect more than one trigger input.
• Verify the control signal and supply against the board’s stated requirements.

A trigger is a control signal, not the amplifier’s power supply. Start-up delays, muting and switching order depend on the complete system design.
