Stereo RTS Headphone Output
The codec has a 6.35mm (1/4") RTS stereo HEADPHONE output for audio monitoring and this can
also be switched to a balanced mono auxiliary line output. The front panel HEADPHONE output and
rear panel HP/AUX OUT share the same hardware output. This means both are switched and
configured together. I.e. both outputs are either a stereo headphone output (default setting), or a
balanced mono auxiliary output.
USB 2.0 Host Port
The USB 2.0 host port can be used for playback of backup audio files on a USB stick, firmware
upgrades, or to attach a USB Wi-Fi dongle to the front panel of the codec.
LED Description
The ALARM LED flashes red when an alarm is active in the codec. It
stops flashing and illuminates solid red after an alarm has been
acknowledged.
The USER LED flashes orange when registering to an active SIP
server account. It illuminates solid orange when the codec has been
registered to an active SIP account successfully. Note: the LED
flashes until all accounts have been registered successfully when
multiple SIP accounts have been added.
When dialing a connection the CONNECTED LED flashes until the
codec connects. Note: It also flashes until all streams / transports
are connected when multiple streams / transports are connecting.
The POWER LED indicates power is connected to the codec.
