2. Introduction
Thank you for purchasing the Orion32+ from Antelope Audio.
Orion32+ is a 32-channel AD/DA converter and audio master clock, supporting ThunderboltTM,
MADI and USB interfaces, clocked by Antelope’s renowned 64-bit Acoustically Focused Clocking
(AFC) technology.
Orion32+ allows up to 192 kHz I/O streaming of up to 32-channels of I/O digital audio through
ThunderboltTM or its custom-built USB chip. The converter also provides up to 64 channels through
its Fiber Optic MADI I/O connections.
Orion32+ supports ADAT protocol as well, offering up to 16 I/O channels. The multi-channel
converter inputs and outputs pass the analog signal through 8 D-SUB 25 I/O connectors.
In addition to being an extremely high quality audio converter, Orion32+ is also an audio master
clock. The two word clock outs, together with the 10 MHz input, make Orion32+ ideally suited to be
in the center of any project or high-end studio.
With its seamless digital routing options, the Orion32+ offers extended flexibility. The device is
managed through a desktop application available for both Windows and OS X. Moreover, it is
equipped with multiple monitor mixers with on-board DSP effects such as EQ, compressor and
reverb.
Connected with MP32, a 32-channel console-grade microphone preamp, Orion32+ ensures a full
transparency of the sound and complete integrity of the signal via the whole chain, from the mic
pres through the conversion, recording and playback, all of them characterized by the signature
Antelope sound.

Orion32+ comes with four software low latency mixers which provide near zero latency mix and
monitoring that can be distributed using the control panel. The new Orion32+ allows a low latency
mix to be distributed to any output.
For example, you can drag all of the thirty-two USB play channels to Mixer 1 channels and then drag
and drop MIX 1 L/R to LINE OUT 1&2 providing a stereo bus mix to LINE OUT channels 1 and 2.
The low latency mixers provide the basic functions of a real mixer such as: Solo, Mute, Pan, Link
channels, Volume Level controlled by faders and a Master Fader, so you can easily make a stereo
mix, plus an Auxiliary send in order to use the DSP effects.
Maximum Number of Channels per Sample Rate:
Sample Rate MADI ThunderboltTM USB ADAT S/PDIF
32 kHz 64 ch 32 ch 32 ch 16 ch total / 8 ch per line 2 ch
44.1 kHz 64 ch 32 ch 32 ch 16 ch total / 8 ch per line 2 ch
48 kHz 64 ch 32 ch 32 ch 16 ch total / 8 ch per line 2 ch
88.2 kHz 32 ch 32 ch 32 ch 8 ch total / 4 ch per line 2 ch
96 kHz 32 ch 32 ch 32 ch 8 ch total / 4 ch per line 2 ch
176.4 kHz 16 ch 32 ch 32 ch 4 ch total / 2 ch per line 2 ch
192 kHz 16 ch 32 ch 32 ch 4 ch total / 2 ch per line 2 ch



AuraVerb is a powerful and flexible algorithmic reverb effect powered by the Orion32+ that
provides near zero-latency effect monitoring without taxing your computer’s processor. AuraVerb
can also be used as a hardware effect from your DAW, so you can take advantage of its rich and
unique ambience effect while mixing or mastering.


Quick Start
AuraVerb appears as a pre-fader send effect on the Orion32+’s mixer 1. To send a signal to the
reverb, turn up the send control on a mixer channel and use the reverb output level to adjust the
return to the mixer’s master channel. To hear the reverb, route the mixer output to your monitors by
clicking and dragging MIX 1 [1] [2] to MONITOR [1] [2] on the Orion32+’s routing matrix. Fine tune
the reverb mix by adjusting the balance between the dry signal on the mixer channel’s fader and
the reverb output level knob.
AuraVerb Parameters
• Color
16
AuraVerb’s Color control allows you to adjust the overall tone of the reverb. On “0” the space
created is darker, like a lushly carpeted area. On “100” the reverb is brightest, which can add some
sizzle to a lead vocal, for example.
• Predelay
PreDelay is common on most reverbs, and allows you to create a bit of space between the source
and the onset of reverb by controlling the amount of delay time that precedes the initial sound from
the reverb. This parameter is used to place the reverberated signal later in time with respect to the
unprocessed signal. Natural settings for this are based on the size of the environment and range
from 0 to 32 milliseconds. Fine adjustment of this parameter with respect to the tempo of the song
or dramatic timing of the piece can help set the feel of the reverb within the mix.
• Early Reflection Gain
This is the linear gain value for all early reflections. These reflections are perceptually grouped with
the direct sound when set at lower levels, and can nicely thicken a track when increased.
• Late Reflection Delay
Among other things, AuraVerb calculates reflected energy from the side walls and ceiling of the
virtual space. Late Reflection Delay controls the delay of these these bursts of reflections, either
to create dedicated echoes or to support the spatial impression of the simulated acoustic space.

8. Advanced User Tips
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.
9. In The Box
●● Orion32+ 32-channel AD/DA Interface with AFCTM Clocking Technology
●● Owner’s Manual
●● Warranty Card
●● Power cable
●● USB cable
10. Troubleshooting
Start up and Sound:
●● Are you running the latest control panel and firmware?
If not, please update your control panel and firmware.
●● Are you correctly routing the audio signal via the routing panel?
For ThunderboltTM or USB playback, route the ThunderboltTM or USB-play channels to
the Line Out channels 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 You Tube 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+ 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 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
ThunderboltTM cable (or the USB cable), then restarting your Computer and finally reinstall
