PTX1000DDS

Compact DDS stereo transmitter 1.000W.

Features

PTXDDS is the ultimate digital evolution of the most sold professional FM transmitter world-wide!

AUDIO PERFORMANCE: clear and transparent sound comparable to CD sound quality made possibile thanks to a noise/signal ratio as high as 90dB, low distortion and stereo separation as high as 70dB!
PRIMARY APPLICATION: Optimal for use as an independent exciter. Adjustable power output from 0 to 100%.
AUDIO FEATURE: incorporated a board with DSP for isofrequency applications (SFN) and a limiter on audio (ITU) to ensure controlled emissions in the spectrum, created COMPLETELY DIGITAL and free from mechanical disturbances.
AUDIO RESCUER: integrated, the established timing and priority of all audio inputs (Analog-Digital-MPX) are programmable.
INTERFACE CONTROL: totally microprocessor-controlled, easily programmed from menu through a large LCD and useful optical ENCODER.
INPUT/OUTPUT INTERFACE: built-in high-performance stereo coder, L&R analogue audio inputs, Mono inputs, MPX composite signal and auxiliary inputs for SCA / RDS signals. S/PDIF, TOSLINK, AES/EBU digital audio inputs are available as standard.
REMOTE CONTROL: built-in telemetry system via GSM modem, battery and battery charger or via WEB or via SNMP (option).
RELIABILITY/CONTINUITY: business continuity is guaranteed by an incredible range and variety of controls, such as Fold-Back control for effective VSRW (Voltage Standing Wave Ratio) protection and IAMLC (Intelligent Automatic Modulation Level Control) to keep modulation level steady.
RDS APPLICATION: built-in digital RDS encoder with UECP standard functions.
EASE OF MAINTENANCE: advanced module engineering ensures extreme of access and simple maintenance.
REGULATORY COMPLIANCE: state-of-the-art technology in full compliance with EC, FCC and CCIR standards.
