10. Routing / Mixer
Here you can select either the routing screen or the Zero Latency Mixer to be viewed on the Software
Control Panel.
11. Routing Mixer
This panel enables you to select inputs and route them to your chosen outputs by simply dragging
and dropping channels. Each input has its own unique color. When routing channels, the input color
will be copied from whichever input you select to whichever output you select. In order to select
multiple tracks hold ‘Shift button’ and click on the input channels, then drag and drop. Right clicking
on the outputs enables you to either mute a track or output a selected frequency from a choice of
two different oscillators that can be adjusted from the Settings tab.
To the right side of the Inputs & Outputs Router are 5 presence indicator lights, which indicate the
presence of a valid signal detected by the Orion³².
Once you select the Clock Source and Sample Rate, this will automatically determine the number of
channels available to you in the Inputs & Outputs Router.
When your Orion³² is slaved to another clock source i.e. USB, the panel will lock, displaying a “Pad
Lock” symbol to the clock source and you also won’t be able to change the presets. This prevents
the changing of sample rates and presets for safety reasons.
12. Low Latency Mixer
The Low Latency Mixer provides near Zero Latency mix and monitoring that can be distributed using
the control panel, allowing a low latency mix to be distributed from any output of the Orion³².
For example you can drag your 32 USB play channels to the “mix channels” and then the MIX L/R
inputs to DAC 1 and 2, providing a stereo bus mix to DAC channels 1 and 2.
The Low Latency Mixer provides the basic functions of a real mixer such as: Solo, Mute, Pan,
Volume Level controlled by faders and a Master Fader, so you can easily make a stereo mix.

8. Advanced User Tips
8.1. Ground Loop Hum and Noise
The design of Orion³² minimizes the possibility of ground loop hum and noise. However, we
recommend the use of shorter, shielded cables and balanced connections for all the audio signals of
your system. All power cables of the system should be connected to a dedicated outlet box or power
conditioner unit to avoid ground current noise affecting the audio signal path. It is also advisable to
keep the layout of your signal and power cables separate.
8.2. Calibration procedure
The Orion³² can be calibrated periodically in order to calibrate the accuracy of the internal clock
by connecting it to the 10M Atomic Clock. This procedure is not typically required often, but when
necessary, please follow these instructions:
● Connect the 10M to Orion³² via the dedicated 10M input;
● Power on the 10M and wait until it reaches operating temperature;
● With the Orion³² in standby mode, press and hold the Antelope button whilst pressing Preset
button 2;
● Leave the buttons and wait for one minute to allow the units to stabilize;
● You will see “Calibration” appear on the display along with “Heating Up” and the temperature
of the Oven;
● Wait for the calibration to take place;
● When the Err. Number becomes stable, press the Preset button 2 again to end the
calibration;
● You will see “DONE” displayed on the LCD screen.

12. Troubleshooting your Orion³²
Start up and Sound:
Are you running the latest control panel and firmware?
If not, please update your control panel and firmware.
Are you in the correct USB mode for your operating system and sample rate? (Mac Only)
While using Macintosh Operating Systems, please be aware that you must be in 24 channel USB
mode when working with sample rates above 96khz.
Are you correctly routing the audio signal via the routing panel?
For USB play back, route the USB-play channels to the DAC channel by dragging and dropping from
the top section to the bottom. For more info on routing see the “Orion³² - Routing with ease” video
from the Antelope Audio Youtube page.
Have you set the correct sample rates matching your DAW with your computer’s sound
and the Orion³²?
On Mac, first check that the sample rate is correct in the audio midi set up, then proceed to check in
the DAW before finally checking the Orion³²’s sample rate.
For Windows, first check in play back devices, right click on the Orion³² then click properties before
then moving to the advanced tab. Then repeat the above by checking the DAW’s sample as well
as the Orion³².
Connectivity:
If you believe there is no sound being received to an input or delivered from an output:
● Check your source. Is there a signal being transmitted form the source?
● Is your source in the correct sample rate for the Orion³² to receive?
● Check what clocking mode you are in. Are you receiving the clock signal from the source?
1
20
● Check that the relevant lock light on the control panel of the Orion³² is lit up.
● Try a different cable and another source if available.
● Check the routing on the control panel. Have you routed the signal path correctly?
● If you have routed signals to the routing mixer, check their corresponding fader is up.
● Check the relevant peak meters of the control panel by selecting them in the drop down
menu to see if the relevant signal is being received or is being outputted.
DAW
What buffer size is your DAW set to?
If it is significantly low i.e. lower than 128 samples in your buffer size, try increasing it. Try increasing
the buffer size from the Orion³² control panel (Windows Only)
Have you checked the input and output routing is correct in your DAW?
Is the Orion³² device selected in the relevant sound card section of the DAW’s preferences?
If the Orion³² doesn’t show up in you DAW, first try unplugging and plugging back the USB cable,
then restarting your Computer and finally re-install the firmware, drivers and control panel for the
Orion³².
