The Quantum 2 from PreSonus is a low-latency audio interface that provides up to 22 inputs and 24 outputs of combined analogue and digital connections. The unit’s convertors allow for low-latency recording as well as dynamic ranges of 120 dB on both AD (analogue to digital) and DA (digital to analogue) conversions. Furthermore, the Quantum 2 captures audio at 24-bit resolution, achieving sample rates up to 192 kHz.

For analogue I/O, the Quantum 2 provides a complement of four inputs and four outputs. Microphone inputs are PreSonus’s recallable XMAX preamps and include two combination 1/4" / XLR jacks for instruments, mic-level, or line-level signals, as well as two combination XLR/TRS jacks for balanced audio in (mic and line-level).The output section includes four 1/4" TRS outputs and a headphone jack with a dedicated volume control.

The digital I/O includes two banks of optical ADAT I/O as well as S/PDIF connections, bringing the grand total of ins and outs to 22x24. You’ll find that the unit sports BNC wordclock connections, facilitating wordclock sync with other pieces of gear in your studio such as a master clock. 5-pin DIN MIDI I/O lets you connect your MIDI controller and send MIDI signals. Six eight-segment LED metres are provided. Thunderbolt 2 ports offer connections to your host computer, and with two of them on hand, you can daisy-chain other compatible devices to and through the Quantum 2. Included with the Quantum 2 is a version of PreSonus’s DAW, Studio One Artist.

Australian Shipping Via DHL
DHL offers a great express shipping service to Australia from New Zealand. We are proud to be able to offer express shipping to main cities on the east coast of Australia, within the same timeframe ( If not quicker ) than local Australian courier companies. Prior to the Covid-19 outbreak, service standards for these main centers was overnight. However these services have been impacted greatly, and as such the overnight service has been suspended. Overnight shipping will likely resume once things have returned to normal.

Qualifying main centers include:

  • Brisbane
  • Sydney
  • Adelaide

Whilst this service is extremely efficient and will likely be delivered within 1-2 days 99.9% of the time, it cannot be guaranteed. In the case where something were to go wrong with your delivery and it doesn’t arrive within the specified time frame, in most cases it will be delivered by the next day.

While not all major cities are eligible for overnight delivery, they still benefit from this great service. Other centers throughout Australia will have a typical delivery ETA of 2-4 days. (Excluding rural delivery address where this ETA can be extended to an additional three or more days).

If you require urgent shipping and you don’t reside in one of the cities stated above, please contact us and we can find a solution that works best for you.

Please Note: Shipping via DHL is not available to PO boxes and/ or parcel boxes etc.
