Quest Commercial Mixing Amplifiers are the ultimate solution for sound distribution systems in small to medium sized commercial premises, delivering the best and highest quality audio at an affordable price. These models have a constant voltage power amplifier allowing use at 25/70V or at low impedance of 4 or 8 Ohms. The M35bt can deliver a power of 35 Watts, and the M65bt a power of 65 Watts. They offer three input channels (terminal block/RCA and 3.5mm on the front panel) with independent level controls to facilitate the connection of sound sources. A music-on-hold feature is also available for businesses wishing to enhance their customers' telephone experience. So when you connect these mixers to a telecommunications system, customers can listen to music or pre-recorded messages while they wait.

These models are equipped with Bluetooth, an FM receiver and a Media player on USB port or SD/SDHC cards.

The M35bt, and M65bt mixer amplifiers are complete all-in-one mixer amplifier solutions for commercial and industrial applications. These low-cost units offer all the necessary features in a simple format:

• Three (3) microphone inputs and two (2) line inputs (terminal block, RCA and 3.5mm on the front panel).
• Rated power output: 35 Watts for the M35bt, and 65 Watts for the M65bt.
• A 2-band tone control helps correct the overall sonic response of the PA system.
• Acceptable wide-range input level (up to 44 dB)
• Terminal block telephone paging input with volume and attenuation level controls.
• Two (2) layer priority muting.
• Bluetooth, MP3 Media player on USB or SD-SDHC card, FM Tuner, with remote control.
• Music on hold (M.O.H.) output used to connect the mixer to the telephone system to play music or pre-recorded messages. This output can also be used to supply a line level signal to a power amplifier.
• Microphone inputs 1 with phantom power for connecting condenser microphones.
• Low distortion and low noise level.
• To ensure long-term reliability, M-Series mixers are equipped with a sophisticated protection circuit with current limiting to avoid problems associated with overloading and overheating.
• Compact size makes it easy to install on a work desk or in a standard 48.3 cm (19 in) rack using optional brackets.
• An ideal solution for commercial and industrial applications.
• An extended three-year warranty.
