Overview
This transmitter adopts the concept of simple design and integrates the exciter and power amplifier, output filter, switching power supply, etc into a 1U high 19-inch standard case. This advanced design reduces the number of connection cables and improves the overall efficiency of the transmitter, making it more reliable and easier to operate.
Functional features
• Humanized digital LCD panel, one-rotary knob control.
• User-friendly digital LCD panel, using one rotary knob to easily control all the setups.
• The integrated LCD screen displays all the parametric including: transmitter frequency, stereo and mono, volume, amplifier tube temperature, audio signal UV meter, forward power, reflected power, modulation mode, pre-emphasis etc,.
• 1U 19-inch thickened all-aluminium case, strong and excellent heat dissipation.
• With built-in high-quality stereo encoder, CD-class sound quality.
• Outstanding power AGC balance control system, adjustable power output from 0 to 50 watts, and automatic gain power control to maintain output power within set range without drifting.
• Signal input supports XLR audio inputs, and also SCA and RDS signals using the BNC connector AUX.
• Supports AES-EBU digital signal input, 24Bit 192KHz sampling rate input range, true lossless audio.
• The RF amplifier uses LDMOS transistors to withstand even severe load mismatch exceeding the 65: 1 VSWR at a 5dB compression point.
