Digital Television Affects Wireless Microphones
The imminent introduction of Digital Terrestrial Television in New Zealand by the Freeview consortium will have an impact on wireless microphone users. Parts of the spectrum currently used by wireless mics will be gobbled up by the new TV transmissions, rendering some wireless mics unusable. With full DTT transmission due to commence in April 2008 there is about to be widespread disruption, particularly for wireless mics that are not able to tune to alternate frequencies.
The Wellington Audio Association (www.waa.org.nz), a body representing largely professional and commercial audio contractors, has formed a steering committee with the intention of lobbying the Ministry of Economic Development on this issue.

NTI extends the functionality of the analog signal generator MR-PRO by introducing the new firmware V2.01. Now Minirator MR-PRO measures the impedance and phase of the connected load and calculates the related power for 70V or 100V distributed loudspeaker systems.
The new MR-PRO firmware V2.01 offers:
- Faster impedance measurement with Apparent Power, Phase and Impedance
- Cable Test Function includes detailed fault information
- Level setting in ”Volt” supports definite linear settings, e.g. 100 mV
- Configuration files may be renamed
