Audio Input Specifications on the Cube product line

Analog audio input

The 1st, 2nd and 3rd generation Cube encoders have a single 3.5 mm (1/8") audio input jack with tip ring sleeve / TRS pin-out for unbalanced audio input.

NOTE: balanced audio input is not supported. If your audio source is outputting balanced audio, you must convert from balanced to unbalanced audio for direct use with the Cube.

Mono and stereo audio input are supported, and configuration is under user control using the device's front panel (2nd and 3rd generation Cube), or through a web browser.

Line level and Mic level analog audio input are supported, and the input level configuration is also under user control.

NOTE: the analog audio input does not provide either plug-in power or phantom power to devices connected to the analog audio input. Microphones must be externally powered to be used with the device.

Voltage level is the consumer audio (-10dBV) rather than the professional audio (+4dBu) signal level.

The analog audio input circuit expects an input of 0.5Vrms (0 dB). The circuit can handle a nominal 0.707 Vpeak and a maximum 0.9 Vpeak.

The input impedance for Single-ended Stereo Operation is 20k.


Headphone / looped audio output

A single 3.5 mm audio output jack (TRS pin-out) is present on the 2nd and 3rd generation Cube encoders to allow local monitoring.

The audio settings on the looped output are not adjustable.



Embedded audio input

The 1st, 2nd and 3rd generation Cube encoders support (2) channels of embedded audio over HDMI or SDI. When SDI input is used, any two of the possible 16 input channels can be selected (e.g. channels 1 and 2, or 15 and 16, or any other combination).
