USES
Using the M205 Mono Power Amplifier
Purpose
- One amplifier chassis for each channel.
Connections
- Connect a preamplifier or volume-controlled DAC to the balanced XLR input.
- The selectable input impedance allows matching to low-impedance MSB outputs; use the setting specified for your source.
Key differences
- Separate chassis keep the two channels’ amplification and power supplies apart.
- The Class A input stage feeds a Class AB output stage.
PRODUCT DESIGN
Design and features
Selectable input impedance
Input impedance sets the electrical load on your DAC or preamplifier. The 75 Ω, 300 Ω and 1.2 kΩ options need a source output capable of driving the chosen load.
Class A input, Class AB output
The Class A input stage handles the incoming signal; the Class AB output stage supplies power to the loudspeakers.
CONNECTIONS
Connections and system matching
Check the inputs and outputs against the equipment you already use. If you have a connection question, send us the model names or a photograph of the sockets.
Connecting and setting up
- Allow stable support and ventilation for each 41 kg chassis.
- Use speaker impedance, sensitivity and listening distance to judge the power your system needs.
Points to consider
- A preamplifier or DAC must control the volume. The power amplifier has no everyday volume control of its own.
- A stereo pair uses two amplifiers, with power and speaker cables for each.
