The Crown 135MA is an outstanding mixer amplifier designed for commercial audio needs. It offers excellent value with 8-ohm and constant-voltage outputs (70V and 100V). Ideal for paging, playing background music, and music-on-hold, this amplifier has 3 inputs, each with its own volume control, and a powerful 35W amplifier output. Key features include a balanced Phoenix-type mic/line input, telephone output, dual RCA stereo music inputs, and screw-terminal speaker outputs. It also has priority muting by VOX or external switch, and bass and treble controls on the master output. Plus, it comes with a three-year, no-fault, fully transferable warranty to protect your investment. Technical specs are great too, with good frequency response, high signal-to-noise ratio, and low THD+Noise.
Using the Crown 135MA is easy. First, connect your audio sources to the 3 inputs according to your needs, like a microphone to the mic input or music players to the RCA inputs. Adjust the volume of each input separately using the volume controls. You can then connect speakers to the screw-terminal outputs. For paging or other priority messages, you can use the VOX or external switch for priority muting. Keep in mind that the amplifier should be used in an environment with a temperature between 0 degrees C to 40 degrees C and 95% relative humidity (non-condensing). Avoid exposing it to extreme temperatures or humidity during storage, and the recommended storage temperature is between -20 degrees C to 85 degrees C. To maintain it, keep it clean and dust-free. Check the connections regularly to ensure they are secure. If you have any issues, refer to the detailed technical specifications or contact customer support.
