USES
Using the S500 Stereo Power Amplifier
Purpose
- High-output stereo amplification in one 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
- Two amplifier channels share one chassis.
- 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.
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 the 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.
- Leave room behind the amplifier for XLR inputs, speaker cables and the mains connection.
