NEW FM EXCITER WITH QSONIC VCO/PLL MODULE, WITH DSP STEREO AND RDS

CYBER MAX FM+ 25W now contains our brand new enhanced FM exciter with DSP stereo encoder finally bringing direct power readout and a wide range of other functions. CYBER MAX FM+ 25W is the smallest from our line of our rack mounted FM transmitter series for demanding broadcasters, operating in the whole band II, from 87.5 to 108 MHz.
Transmitter consists of a new advanced FM exciter (MAX PRO 4025+) and DSP stereo encoder which includes pre-emphasis circuit, active low-pass filter, limiter, compressor and even audio processor. Advanced FM exciter guarantees 25W of clean signal. No tuning is necessary, design is entirely wideband. All you have to do is set the frequency and change sound processing parameters, if desired. SWR, temperature and polarity protection make it very difficult to destroy the unit. Unit is housed in a brand-new professional 19" rack, new design is lighter and RF tight (does not leak RF). It is rugged and made for 24/7/365 operation. Each unit has a wide-angle high contrast backlit LCD display. This unit can give up to 30W of clean RF power, but this is not recommended for long term operation (20-25W is recommended for long life) .
RDS parameters can be programmed with the help of a PC via serial RS232 connection (this requires RDS encoder, USB/RS232 cable and software are included). RDS encoder does not require PC afterwards, only when you want to change settings.

What advantages does new 25W exciter (MAX PRO 4025) bring:
- More power, up to 30W
- New FM exciter inside
- New PLL and VCO (QSONICtm)
- Completely flat audio response across entire FM BAND
- Better efficiency, less generated heat and better heatsink
- Shows all parameters of the previous models plus current consumption (see below)
- Shows forward/reflected power on LCD in watts
- Shows temperature on LCD in degrees C
- Shows supply voltage on LCD in Volts
- Shows uptime without power down or reset on LCD in minutes, hours and days
- Shows audio volume on LCD (audio level bar)
- Fan moved to the back and practically silent, fan powers down at low power output
- Gives full power even at 12-13V (previous model required 15V for full RF power)
- Unit operates and PLL locks across the entire band even at 10V
- No audible artifacts in RF signal from fan operation
- You can disable welcome screen with our logo or ask for custom logo (first time order 25 euro, later free
- You can disable keys internally to prevent users from changing settings

General features:
- Frequency range 87.5 to 108MHz (ask for Japanese band)
- Smallest PLL step 50KHz (50/100/200/500KHz can be selected)
- Output power: 20-25W typ (up to 30W max.), adjustable from 0 to max via LCD or internal trimmer if you prefer
- Output impedance: 50 unbalanced, VSWR less than 2:1 for full output
- RF output connector: BNC female (rear panel)
- Audio input connectors: RCA (cinch) and XLR (DSP version)
- Audio level: 1Vpp
- Audio input impedance: 10Kohms
- Pre-emphasis: Flat, 50 or 75usec, adjustable
- RF Spurious: >-80 dBc @ +- 1MHz min. away from carrier
- RF Harmonics: > -55 dBc Standard
- Monitoring Led: Power on, SWR/TEMP/PLL error
- Harmonic distortion (THD): > 0,1% ( 0,05% typ. )
- Channel separation: 40 dB min., ( 55 dB typ. ), 20Hz to 15kHz
- Power supply: DC 12-15V/4A or mains
- Standard 19" 1HE rack, 13cm deep (about 5")
- Weight 2kg

Note: This popular unit is now available in 4 versions.
- Regular version has a basic stereo encoder, no DSP functions and no RDS
- DSP version has a profesional DSP stereo encoder, XLR inputs and no RDS
- DSP/RDS version has both, profesional DSP stereo encoder with XLR inputs and RDS encoder
- Model C was removed, but we preserved model D to prevent confusion for old customers
- MONO version without stereo encoder for those with no need for stereo

What are the benefits of DSP stereo encoder?
Very shart input filters with a deep 19KHz notch, advanced signal processing with compressor and limiter, all adjustable via LCD display

What is RDS?
Radio Data System, basically it displays station name and sometimes song name and similar information on a compatible radio receiver. Very popular in Europe, less so in the US. Requires connection to a PC at the time of programming, but retains settings even when powered off. Serial programming cable for COM port is included.

What are XLR inputs?
These are balanced audio inputs, usually used by professionals. Their advantage is immunity to noise and ground loops. Hum and other noise artefacts that sometimes torment operators due to ground loops usually magically dissapear once XLR inputs are used.
