Description

The RPM181/O Omnidirectional Polar Pattern Capsule by Shure is one of four interchangeable capsules for Shure's Beta 181 side-address instrument microphone. It features a locking ring which provides a secure connection with the Shure RPM181/PRE. Paired with this preamp, its compact design weighs only 145 g and gets close to any source even in the tightest conditions. With its wide frequency response and high SPL handling, it's great for capturing room ambience, string ensembles and used as a mono drum overhead. It also performs with little to no crossover distortion and provides exceptional low-frequency reproduction.

The capsule is made with a hardened steel mesh grille that resists denting, wear and abuse. Along with its compact form factor, the diaphragm provides exceptional audio with consistent, textbook-like polar responses resulting in a mic with noteworthy sound and versatility.

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.
