Can I use Logic Pro?

Yes. However, early versions of Logic Pro 8 had issues with FireWire audio interfaces. These issues were resolved in Logic Pro 8.0.2.

We recommend using Software Update to ensure that you always have the latest Logic patches. For more information, please refer to the troubleshooting guides: Logic Pro 7 and Logic Pro 8 & 9.

Which DAW can I use?

Orpheus and ADA-8 can be used with any DAW or application that supports ASIO or WDM drivers (Windows), or Core Audio (Mac OS X).

Why can’t my computer see the FireWire module?

Ensure that the FireWire card is being detected by the ADA-8/ADA-8XR hardware by using the “Interrogate Modules” option in the ADA-8/ADA-8XR’s menu.

Next, ensure that the Source and Destination of both paths is set to the relevant slot which houses the FireWire card. If in doubt, re-load the factory FireWire store.

Finally, check that your operating system is suitable and that your FireWire ports are functioning correctly. Windows users may have to re-install the FireWire drivers when adding a new FireWire card.

If you still have problems, please contact tech.support@prismsound.com.

Which operating systems are supported for the FireWire module?

The FireWire I/O Module type PREV039/10/1 can be used with both Apple Mac and PC.

Mac:

  • macOS 10.4.11 to macOS 12.6.
  • In macOS 13 Ventura, Apple removed support for Core Audio over firewire so the Orpheus and a multitude of other firewire devices will no longer work.
  • You will need to download & install the FireWire module control panel for Mac in order to select sync sources correctly.

PC:

As with any software, it is advisable to create a system back-up prior to installation and to back-up your data regularly.

How long can my FireWire cable be?

The Firewire 400 (IEEE 1394-1995) standard specifies a maximum cable length of 4.5m.

It is possible to extend this range by using active repeater cables, or to extend it to many hundreds of metres by using fibre-optic extenders.

How can I add another FireWire bus to my computer?

Additional FireWire buses can be added to with FireWire expansion cards.

We recommend that you use cards that have an OHCI compliant Texas Instruments chipset.

Cards with S800 ports are not recommended because there are technical difficulties in manufacture that may cause them to be more unreliable than S400 cards. In any case, S800 cards are more expensive and provide more bandwidth than necessary for Orpheus.

How much delay compensation do I apply on the Pro Tools HD Hardware Insert Delay feature?

The amount of delay required varies depending on the sample rate.

ADA-8 and ADA-8XR Pro Tools HD – Hardware insert delay

Pro Tools HD allows users to specify the latency of outboard hardware (such as effects devices) in the H/W Insert Delay page of the I/O Setup dialogue. You can enter hardware insert latency, in milliseconds, in a field that corresponds to every input/output pair. These times will be used by the Delay Compensation Engine to time align input paths when a hardware insert is used.

To set an insert delay offset: Enter a value, in milliseconds, in the field corresponding with the input where the hardware insert is connected.

NOTE: Insert delay offsets only have an effect when the I/O is used for hardware inserts.

The following table show the delay compensation that can be applied in the Hardware Insert Delay feature of Pro Tools HD when using the Prism Sound ADA-8 and Prism Sound ADA-8XR multi-channel converters:

Sample RateADA-8 DelayADA-8XR Delay
44.1 kHz2.6 ms1.95 ms
48 kHz2.41 ms1.79 ms
88.2 kHz1.3 ms0.98 ms
96 kHz1.26 ms0.9 ms
176.4 kHz0.49 ms
192 kHz0.45 ms

What is the Null-Modem (serial) cable pin-out

The pin-out for the Null-modem cable supplied by Prism Sound for use upgrading the software of the ADA-8 and other equipment is as follows.

DB-9 Socket DB-9 Socket
1 and 6 To 4
3 To 2
2 To 3
4 To 1 and 6
5 To 5
7 To 8
8 To 7

However, if you are building a cable yourself, you only need to connect to the following:
