Page 4: Introduction
M35bt / M65bt Introduction M35bt / M65bt Welcome! Thank you for choosing this Quest Commercial M-Series Mixer Amplifier! 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. -
Page 5: Features
M35bt / M65bt Features 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 ( , RCA and 3.5mm on the front panel). - Page 6 M35bt / M65bt 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.

Speaker output connector – This 5-contact terminal block connector allows the use of 25V or 70V constant voltage loudspeakers, as well as low impedance loudspeakers of 4 or 8 ohms. MoH (Music on Hold) terminal - This 3-contact terminal block connector allows the mixer to be linked to a commercial telephone system to provide a music source when a call is put on hold.

Page 8: Installation
M35bt / M65bt Installation CAUTION: Before you begin, make sure your mixer amplifier is unplugged from the power source, the power switch is in the "OFF" position, and all volume controls are set to minimum level (turned counterclockwise). Location: Take the unit out of its packaging (keep it for any return to the workshop). The M35bt, and M65bt mixing amplifiers can be installed in a standard 19”... - Page 9 M35bt / M65bt 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 M35bt / M65bt 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).

M35bt / M65bt 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 M35bt / M65bt 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. To prevent the possibility of shorting, wrap or insulate exposed speaker connectors.
- Page 13 M35bt / M65bt Wiring Guide Speaker connections are shown in Figure 2.2 [Figure 2.2 How to connect speakers] WARNING: Never use the low impedance (4Ω / 8Ω) and high impedance (25V, 70V) outputs simultaneously. [Figure 2.3 Wrong connection]...

M35bt / M65bt 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 M35bt / M65bt 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 connector of the first is used to power the second and so on.
