Leonis Cinema – SMA-OBIA

LIDSA32 (Immersive Digital Surround Amplifier-32 Channels) belongs to digital input CLASS-D power amplifier, digital interface access system, it adopts digital processing method in the whole process of signal processing and power amplification, in order to promote the speaker ,it uses low-pass filter to extract the analog audio signal in the CLASS. SMA-OBIA belongs to digital input CLASS-D power amplifier, digital interface access system, it adopts digital processing method in the whole process of signal processing and power amplification, in order to promote the speaker ,it uses low-pass filter to extract the analog audio signal in the CLASS. Each digital-analog conversion will produce a loss of sound, SMA-OBIA link reduces DAC conversion link. So our structure is more rational, more integrated. The sound of the output will be direct, dynamic amplitude larger, transient better. It effectively overcomes defects of the traditional analog amplifier (such as big volume, big distortion, low power efficiency, etc.). Its power utilization rate can be up to 95%. Features:
  • High integration,32 channels output
  • High power output, attain to cinema level
  • Digital input interface
  • 32 channels analog output
  • Over-current protection, overvoltage protection, over temperature protection
  • Adjust acoustic gain, status display, BTL-PBTL mode switch of per channel by network protocol

  • AMC

AMC – iAC120

Single-channel Class-D amplifier with 120 W power output. Created for 100 V and low impedance high-quality background music systems. Containing Dante digital input card, Balanced Phoenix & Stereo RCA input and audio link output connectors. Amplifiers have an RS232 control port for integration amplifiers with third-party automation systems that allow using iAC amplifiers in large and complex audio systems that can be automated and controlled remotely. Due to the integrated signal processor, amplifier‘s volume level, tone control, mute, and standby status can be controlled with a rotary selector as well as by RS232 protocol.
