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

Marani – MDA4-750PS

MDA4-750PS is a highly flexible, powerful and intelligent 4-Channel power amplifier delivering up to a total of 4x750W @ 4 ohms and 4x870W @ 2 ohms, or able to drive 70V/100v Constant Voltage Lines MDA4-750PS is a highly flexible, powerful and intelligent 4-Channel power amplifier delivering up to a total of 4x750W @ 4 ohms and 4x870W @ 2 ohms, or able to drive 70V/100v Constant Voltage Lines. The 4 output channels can be bridged into 2, and provide 1500W@8ohms power output. Designed to meet the most demanding portable and fixed installation sound systems, it provides a full set of value added features such as high output power, efficient cooling system, on board DSP and USB/Ethernet for monitoring and control via PC software. MDA4-750PS includes a highly efficient Switch Mode Power Supply, which provides power to the output stages. The 4 output stages use the well-proven Class D module-full bandwith PWM modulator obtaining ultra low distortion, high efficiency and also equipped with a full set of circuit protections. Furthermore the Clip/Limiter function provides output monitoring to prevent speaker damage with gentle gain reduction at clip threshold, in addition to the efficient heat dissipation system and Over-Heat protection which themselves ensure uncompromised reliability. MDA4-750PS is more than just an amplifier. It is also a capable and sophisticated loudspeaker processor, thanks to its powerful MARANI® DSP running 96 kHz / 24 bit [ 96 bits precision for the internal intermediate processes] and high performance 24bit AD/DA Converters. It offers 4 channels of slope up to 48dB/Oct IIR HP/LP crossover filters, or up to 512 taps FIR filters[FIR coefficients can be imported as .txt/.csv  file from external application] , RMS compressor, parametric Eqs , alignment delay and white/pink noise internal generator, everything needed to optimize a loudspeaker system.

Glensound – Athens 2

Athens 2 is twin stereo phono preamplifier with excellent RIAA equalisation suitable for both moving magnet and moving coil turntable cartridges. It has redundant network circuits with 2 x copper & 2 x SFP interfaces. Athens 2 is twin RIAA phono preamplifier with Dante® and AES67 network audio outputs. It is a mains powered device with two high quality stereo turntable preamplifiers inputs. Each preamplifier has its own set of preset controls to allow accurate matching of the Athens 2 input circuitry to the turntable's cartridge. Input gain, input impedance and input capacitance can all be set for each of the two stereo inputs.The Athens 2 is suitable for use with both moving coil and moving magnet cartridges. To provide the best possible equalisation of the RIAA curve the preamps feature high quality high tolerance analogue circuitry followed by a high quality analogue to digital converter and DSP. The combination of the analogue circuitry and DSP provides a very good quality RIAA equalisation resulting in a very flat output.
