Page 4: Introduction
These models have a constant voltage power amplifier allowing use at 25/70V or at low impedance of 4 or 8 Ohms. The M35 can deliver a power of 35 Watts, and the M65 a power of 65 terminal block Watts. -
Page 5: Features
M35 / M65 Features The M35 and M65 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 ( , RCA and 3.5mm on the front panel). - Page 6 M35 / M65 M-Series – Front Panel Presentation [Figure 1.1 Front panel diagram] 1. Input Channel Volume – These three knobs determine the level of the sound sources connected to the inputs. 2. Tone Control – These two knobs adjust the overall frequency response of the system. They allow up to 10dB of cut/boost on the 100Hz and 10kHz bands.

Page 8: Installation
Location: Take the unit out of its packaging (keep it for any return to the workshop). The M35 and M65 mixing amplifiers can be installed in a standard 19” equipment rack or on a shelf. To install the unit in a standard 19” equipment rack, the optional RK-M3565 Rack Bracket Kit must be ordered at time of purchase. - Page 9 M35 / M65 Installation Using a constant voltage system – continued The same principle applies to constant voltage audio systems. A transformer connected to the output of the amplifier increases the voltage and reduces the output current, allowing the use of long, smaller-diameter cables to link multiple speakers with step-down transformers.
- Page 10 M35 / M65 Installation Connecting sound sources Then connect the sound source to the terminal block input connectors on the back. If your console has balanced outputs, use balanced three-conductor connections and connectors (you can use unbalanced connections, but you'll get better sound quality and less noise if you use balanced connections).

M35 / M65 Wiring Guide Wiring plans Choose the input connector and the appropriate cable for each source. We recommend the use of pre-assembled or professionally assembled 22-to-24-gauge balanced cables. Figure 2.1 shows the connection diagrams for the different connectors. RCA input connectors can also be used as unbalanced inputs. - Page 12 M35 / M65 Wiring Guide Wiring plans – Continued Choose the output connector and the appropriate cable for each source. For the amplifier output connectors, we recommend the use of pre-assembled or professionally assembled speaker cables of high quality and of sufficient gauge. You can use pluggable terminal blocks for your output connectors.

M35 / M65 Operations Input Signals Gain Control. The Quest Commercial Mixer Amplifier can accept wide range and variable input signals thanks to the gain adjustment potentiometers. Adjust the gain potentiometer within a range of 44dB to accommodate different external equipment. Figure 3.2 shows the detail of input sensitivity. - Page 16 M35 / M65 Operations Using the Music on Hold (MoH) output to power a 2nd zone For use for 2 or more zones, the example below illustrates the installation that can be done when the unit is used in conjunction with a 2nd unit. The MOH / Line Out connector of the first is used to power the second and so on.
