1.2 Hearing Damage – IMPORTANT!
Please exercise caution and avoid listening to music at excessive volume. The following excerpt
is from the CDC website:
“Hearing loss can result from damage to structures or nerve fibers in the inner ear that respond
to sound. This type of hearing loss, termed “noise-induced hearing loss,” is usually caused by
exposure to excessively loud sounds and cannot be medically or surgically corrected.
Sound intensity is measured in decibels with a sound level meter. Noise-induced hearing loss
can result from a one-time exposure to a very loud sound (at or above 120 decibels), blast,
impulse, or by listening to loud sounds (at or above 85 decibels) over an extended period. The
louder the sound, the shorter the time period before hearing damage occurs.”
Listen smart, protect your hearing!
1.3 Output Power – IMPORTANT!
In order to drive low efficiency and/or high impedance headphones effectively, the OriGen+ is
built with powerful headphone outputs. At the 0dB gain setting, the headphone output jacks are
capable of 5.6 Vrms output with the volume knob at maximum. Please be sure to take the
following precautions each time you use the OriGen+:
•
Always start with the gain switch set at -10dB.
•
Always start with the volume no higher than the 9 o’clock position.
•
Never switch to a different pair of headphones without first restoring the above
default safe settings.

4 Usage
Basic operation of the OriGen+ is simple, just turn on the OriGen+ and adjust the volume knob
to the desired playback volume. This section describes the features of the OriGen+ in additional
detail, along with recommendations on how to maximize performance and listening enjoyment.
4.1 Signal Display Grid
To help indicate the current operating status, the OriGen+ has a grid of 10 display lights above
the volume control knob. The following describes the information conveyed by each status light.
Label
PCM
DSD
44.1
192
Description
The USB input signal type is PCM. No display for Optical input.
The USB input signal type is DSD. No display for Optical input.
These group of six lights indicate the sampling rate of the current
USB input audio signal, including 44.1kHz, 48kHz, 88.2kHz,
96kHz, 176.4kHz, and 192kHz. No display for optical input.
Volume level indicator light. This light has a blue and a red
component, corresponding to the left and right channels. When
both channels have a signal, the light will be purple. At relatively
low playback volumes, the light may not appear to turn on at all.
Power indicator. Turns blue when a valid signal is detected, red
when a valid signal is not detected. No light when turned off.
4.2 Knobs and Switches
4.2.1 Volume Control
The volume knob on the OriGen+ is also the power on/off switch. Always start each use with the
volume knob no higher than the 9 o’clock position. Adjust to the desired listening level. If you
switch output devices or headphones during use, remember to lower the volume to the 9 o’clock
position first.
The OriGen+ does not need to be turned off when not in use. Some computers will continue to
supply power to the USB port when shut down. In this case, the LED indicator lights on the
OriGen+ will continue to be illuminated even when the computer is off. This is normal and will
not cause any issues.
4.2.2 Input Selector Switch
The input selector switch toggles between USB and the Optical S/PDIF input. Both inputs can
be connected at the same time, though only one will be selected for use as the input signal.
4.2.3 Output Selector Switch
The output selector switch is used to output signal to either the rear analog stereo output, or the
front headphone jacks. Both cannot be used at the same time. If there is a need to output signal
to a downstream amplifier and a pair of headphones at the same time, this can be accomplished
by connecting both the amplifier and headphones to the front headphone jacks.

Page | 13
4.2.4 Gain Switch
The gain switch adjusts the output level of the OriGen+ as needed to properly drive the attached
device or headphones. The maximum output signal level corresponding to the gain switch
setting is as follows:
Setting
0dB
-10dB
Output Levels
5.6Vrms for all analog outputs
1.7Vrms for all analog outputs
The 0dB setting is suitable for driving amplifiers with low input sensitivity, or headphones with
low efficiency and/or high impedance. Always start with the gain switch in the -10dB setting and
the volume control at the 9 o’clock position. Switch to the 0dB position only when needed.
4.3 Inputs
4.3.1 USB Input
The micro USB input jack is used to connect the OriGen+ to a computer’s USB connector. Make
sure that the OriGen+ is connected to a USB jack on the computer. If using a desktop computer,
make sure to use one of the rear USB jacks. Use only the USB cable that came with the
OriGen+. It’s not a magical cable, but it is a good quality cable that we know works. Set the
input selector switch to USB when using USB as the signal input.
The USB input also functions when used with compatible mobile devices that support OTG USB
Audio. Since support for OTG USB Audio is not universal, this functionality is dependent on the
specific mobile device and is therefore provide only on an as-is basis. Because the USB port on
most mobile devices does not provide power output, a separate 5V DC power adapter (not
included) will be needed for this functionality.
4.3.2 Optical S/PDIF Input
The OriGen+ Optical S/PDIF input accepts PCM signals up to 24-bit/192kHz from devices such
as computers, DVD players, TVs, and etc. Set the input selector switch to Optical when using
Optical as the signal input.
When using the Optical S/PDIF input, the OriGen+ must be powered either through the USB
jack, or the DC input jack. Any USB power source, such as a computer USB port, or USB phone
charger is acceptable.
Please note that the LED indicators for PCM/DSD and bit rate only show information for the
USB input and therefore will not display information for the Optical S/PDIF input.
4.3.3 DC Input Jack
The DC input jack accepts 5 volt DC power adapters (not included) for use when the OriGen+ is
attached to a compatible mobile device through an OTG USB Audio connection. While it is
possible to use the DC input jack to power the OriGen+ when using the Optical input, it’s more
convenient to use the USB port for power instead.

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 USBto-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.
