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

Australian courier companies. Prior to the Covid-19 outbreak, service standards for these main centers was

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).
