Professional reliable no-tune 10 W FM transmitter
This product has been temporarily sold out, we expect new version towards the end of summer. Please use MAX PRO 3+ instead (it is a superior product anyway).
MAX PRO IV+ is an answer for those looking for a reliable 10W exciter with an unbeatably wide array of features. This no-tune wideband FM transmitter offers SWR protection, temperature protection, and LCD display for easy digital frequency and power adjustment (via up/down keys). It comes with many nice additional goodies, such as a schematic, parts list, included trimmer for fine-setting the PLL to the last hertz (which none of the competitive units have), on-board connectors for power, audio input, audio level trimmer, built-in pre-emphasis (jumper selectable 50uS and 75uS), and expansion connector for direct connection with SE4 DSP+. It is possible and easy to connect this unit to our SE4 DSP stereo encoder, making it possible to use same LCD display unit to set Mono/Stereo operation, preemphasis, compressor/limiter settings and bass/treble.
Power can be adjusted either by LCD menu system or fixed to one of the preset levels by internal jumpers (thus preventing the user fiddling with the boxed unit).
A 15W final transistor has been used, but is only driven to 10W to offer exceptional reliability. A new efficient heatsink has been developed especially for MAX PRO IV+ to ensure reliable operation.
To sum it all up, the most notable points are:
- true wideband no-tune operation
- high power, 10W (can be extended to 15W), making it possible to drive most 100-300W stages directly
- directly supports our SE4 DSP+ stereo encoder via LCD MENU system
- SWR and over-temp protection
- Schematic included
- Available as a KIT also Have a quick look at the MAX PRO 4 manual here!
