Orion Studio 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 Orion Studio allows a low
latency mix to be distributed to any output.
For example, you can drag all of the twenty-four 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 ThunderboltTM USB ADAT S/PDIF
32 kHz 32 ch 24 ch 16 ch total / 8 ch per line 2 ch
44.1 kHz 32 ch 24 ch 16 ch total / 8 ch per line 2 ch
48 kHz 32 ch 24 ch 16 ch total / 8 ch per line 2 ch
88.2 kHz 32 ch 24 ch 8 ch total / 4 ch per line 2 ch
96 kHz 32 ch 24 ch 8 ch total / 4 ch per line 2 ch
176.4 kHz 32 ch 24 ch 4 ch total / 2 ch per line 2 ch
192 kHz 32 ch 24 ch 4 ch total / 2 ch per line 2 ch

AuraVerb is a powerful and flexible algorithmic reverb effect powered by the Orion Studio 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 Orion Studio’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 Orion Studio’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
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.

of the Orion Studio internal clock (eg. If you want the clock to run at 192 kHz and your S/
PDIF input is at 44.1 kHz, simply press this button to match the sample rate frequency of
the Orion Studio internal clock).
8. Advanced User Tips
Ground Loop Hum and Noise
The design of Orion Studio 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.

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 “Orion Studio - 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 Orion Studio?
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 Orion Studio sample rate.
For Windows, first check in play back devices, right click on the Orion Studio then click
properties before then moving to the advanced tab. Then repeat the above by checking
the DAW’s sample as well as the Orion Studio.
11. Windows, only: ASIO Control – Buffer Size & USB Streaming Mode
12. Display Brightness : Adjusts the brightness of the display screen of the Orion Studio

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 Orion Studio to receive?
●● Check what clocking mode you are in. Are you receiving the clock signal from the source?
●● Check that the relevant lock light on the control panel of the Orion Studio 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 Orion Studio control panel (Windows Only)
●● Have you checked the input and output routing is correct in your DAW?
●● Is the Orion Studio device selected in the relevant sound card section of the DAW’s
preferences?
If the Orion Studio 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
re-install the firmware, drivers and control panel for the Orion Studio.
