The 3506A Stereo Kit with 4006A Omnidirectional Microphones by DPA Microphones is a kit for the crucial capturing of instruments or vocals in recording and live sound reinforcement applications. The 3506A kit includes two frequency matched 4006A omnidirectional microphones; two APE30RS acoustic pressure equalizers, 30mm ball; two APE40RS acoustic pressure equalizers, 40mm ball; two APE50RS acoustic pressure equalizers, 50mm ball; two DD0251 free-field grids, silver; two DD0254 close-miking grids, trapezoid silver; two DD0297 diffuse-field grids; two UA0777 nose cones; two US0896 foam windscreens; two UA0961 microphone clips; and one UA0837 stereo boom excluding holders.

The specially selected 4006As are matched within ± 0.5 dB on frequency range, sensitivity and self noise. The high sensitivity, low noise-floor and extremely linear frequency response of the microphone pair makes the 3506A kit a great choice for all professional A-B stereo recordings.

Key Features

  • The kit includes a frequency and sensitivity matched pair of 4006A omnidirectional microphones
  • Exceptional linearity, particularly at the high-end
  • Clean, neutral sonic character
  • Omnidirectional polar pattern
  • Ideal for A-B stereo pairs for symphonic concert hall recordings

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.
