Description

The Royer R-DB20 dBooster boosts the signal of ribbon and dynamic microphones by making use of 48V phantom power, doing so while protecting ribbon mics from phantom power and providing electrical isolation. As such, the box raises the overall level of these mics without adding colour, noise, or distortion.

Two levels of boost are on hand: 12 and 20 dB, selectable on the front panel. You can plug a high- or low-impedance source into the dBooster and still get a significant amount of headroom and gain out of the device. This is due, in no small part, to the use of Class-A input circuitry.

The low-impedance output of the R-DB20 dBooster offers a signal optimised to drive a digital interface or a standard microphone preamp, allowing you to use long cable runs with minimal signal loss to boot.

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.
