HDX IR Remote

Table Mic LED Event

In stand-alone SoundStructure applications without an HDX codec, the HDX

IR remote may be used to control SoundStructure devices that have both ver-

sion 1.3 firmware and an external IR remote receiver. To use the HDX IR

remote transmitter, add an HDX IR remote to the project and connect the

receiver physically to the SoundStructure as shown in the following figure.

PIN 5: GROUND

This event maps the mute state of the microphone

inversely to the digital_gpio_state of the LED. If the

microphone is muted (mute=1) then the LED is turned

off (digital_gpio_state=0. If the microphone is unmuted

(mute=0) then the LED is turned on

(digital_gpio_state=1).

This event maps the gate state (am_gate parameter)

directly to the digital_gpio_state of the LED. If the micro-

phone gates on (am_gate=1), the LED is turned on

(digital_gpio_state=1). If the microphone gates off

(am_gate=0), the LED is turned off

(digital_gpio_state=0).
