4.4 Outputs

4.4.1 Rear Analog Stereo Output

The 3.5mm rear output jack provides analog stereo audio output that can be used to drive a

downstream device such as an amplifier or powered speakers. The output signal level is

adjustable based on the volume control as well as the gain switch. Be sure to start with the gain

switch setting at the -10dB position and switch to 0dB only if additional output signal amplitude

is needed.

4.4.2 Optical S/PDIF Output

Also built into to the 3.5mm rear output jack is also an optical output that accepts mini optical

jacks for connection to an outboard DAC. When used this way, the OriGen+ functions as a USB-

to-S/PDIF transport and does not perform any signal decoding or volume control function. This

is useful for providing high quality digital audio signal to an audio system that otherwise does not

have an USB interface of its own.

When the USB input is a PCM signal, the Optical S/PDIF outputs the same signal. When the

USB input is a DSD signal, the Optical S/PDIF output will be silent.

4.4.3 Headphone Outputs

The OriGen+ is equipped with two headphone jacks for connecting headphones with 3.5mm or

6.3mm (1/4”) headphone jacks. The headphone output signal level is adjustable based on the

volume control as well as the gain switch. Be sure to start with the gain switch setting at the -

10dB position and switch to 0dB only if additional output volume is needed.

The two headphone output jacks are in parallel, so two pairs of headphones can be connected

in parallel. The minimum recommended impedance for headphones used with the OriGen+ is 16

Ω. If using two pairs of headphones in parallel, the minimum recommended impedance is 32 Ω

per headphone.
