TOA A-1700 Series Mixing Amplifier


The A-1700 Series of high-performance mixing-dedicated power amplifiers are ideal for PA applications that value versatility. Specifically designed to satisfy the multi-microphone public address requirements of environments such as places of worship and meeting halls, the A-1700 Series Microphone Mixing Amplifiers focus on operational flexibility as well as advanced functions, proving an ideal cost-effective PA solution.

Multiple Inputs / Outputs

Featuring multiple mic inputs as well as three auxiliary inputs (2 stereo),the A-1700 Series of amplifiers have three different power ratings to select from depending on the venue. These units offer efficient mixing of as many as 9 different inputs. If more aux inputs are required, mic inputs 5 and 6 can be switched over to accept line level inputs

Phantom power provided

The A-1700 Series of amplifiers provide phantom power to all connected microphones. Phantom power can switched on or off as needed. The microphone inputs feature a balanced configuration with XLR connectors, allowing long cable runs without any problems.

Connecting External Equipment

For more sophisticated equalization such as minimizing feedback, a parametric equalizer or other gearcan be patched in before the power amplification stage. Other equipment such as a delay unit can also be connected if required. Alternately, to extend sound coverage, and additional power is needed to power other speakers, the line out terminal can be used to send the mix output to another power amplifier. Remote Control

2 Zone coverage

Each A-1700 Series amplifier has 2 speaker output zones which can be independently selected or used together for enhanced PA applications.
