Just Released The All New

NRG PLL-PRO7

Designed and Manufactured In New Zealand All NRG transmitters are type approved for LPFM use in New Zealand and carry all required regulatory labels Power output is only adjustable via on-board controller inside case, 0 to 10Watts Output– This is required for compliance with NZ LPFM regulations

The audio frequency response is absolutely level and linear from 30Hz to 57KHz to provide only the highest transmitter FM modulation quality. Not only this but the PLL is dual speed for a fast lock with 2 seconds then switching to a very low loop constant. No more distortion of low audio frequencies and no more tilt. If this wasn’t enough the oscillator is immune to RF feedback and hum since it operates on a completely different frequency to the output stages. Your listeners will receive crystal clear sound and an excellent stereo performance.
