Overview
This transmitter adopts the concept of simple design and integrates the exciter and power amplifier, output filter, switching power supply, etc into a 2U 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 touch panel, simple operation interface with direct touch control.
The integrated LCD displays all system parameters: transmitter frequency, stereo and mono, volume, amplifier tube temperature, audio signal UV meter, forward power, reflected power, modulation mode, and pre-emphasis etc.
2U 19-inch thick aluminum alloy case, which is not only sturdy but also has good heat dissipation.
Precise PLL frequency generation system to ensure the frequency does not drift within at least 10 years.
Built-in high-quality professional stereo encoder.
Excellent power AGC balance control system, the power output can be adjusted from 0 to full power, and has automatic gain power control to maintain the output power within a set range without drifting.
Support external input modulation RDS or SCA signal.
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.
Automatically record 9 latest device alarms for later troubleshooting.
