MA-103

MA-103

The MA-103 is a compact mixing amplifier thatrequires BGM and voice amplification in lecture halls, training centers,restaurants, cafes, etc. It can be used conveniently in a small space due toadaptation of high efficiency digital amplifier circuit. It has highreliability, low weight and low heat generation, also can use MIC, LINE inputaccording to any type of application. It is a device that implements variousadditional features such as tone control, TEL IN and priority function in acompact size.

Description

  • Compact Design - Half rack size compact design and function provide ease of installation
  • Digital Amplifier Circuit - 30W rated power of high efficiency digital amplifier circuit guarantees high reliability, low weight, and low heat. SMPS Power Supply Circuit - Stable
  • SMPS (Switching Mode Power Supply) circuit provides low power consumption and low weight.
  • Various Inputs and Additional Functions - 3 channels various (3.5mm 3P EURO input, 6.3Φ and 3.5Φ Phone Jack, RCA cable) inputs are available. TEL IN and priority function is also provided.
  • Tone Control Function - Depending on the frequency used, there are treble and bass controllers to adjust the tone to suit your surroundings and purpose. (At 300Hz and 10kHz, each adjustable ± 10dB)
  • Priority Broadcast Function - Priority broadcasting function is adopted which can control other input signals by input signal of TEL IN and INPUT 1. (TEL IN >> INPUT 1 >> INPUT 2 = INPUT 3)
