USES
Using the M500 Mono Power Amplifier
Purpose
- High-output amplification with separate left and right chassis.
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.
- Three gain settings allow adjustment for the source output level.
PRODUCT DESIGN
Design and features
Three gain settings
Three gain settings adjust how much the input signal is amplified, helping you find a useful volume-control range with your DAC or preamplifier.
Quad-balanced Class A input
M500 uses a quad-balanced Class A input stage for the incoming signal and a Class AB output stage to drive the loudspeaker.
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 74 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.
