Overview

3 Overview
The high performance 904 Power Amplifier is a power amplifier for stereo
audio balanced signals. It can output up to 75 Watts RMS per channel, as it
uses the latest Class “T” technology for highly efficient conversion1 to the
pair of loudspeakers with the absolute minimum power loss.
The 904 includes:
An OUTPUT LEVEL control knob to adjust the output signal
OUTPUT LEVEL multi-color LED2 indications for left and right speakers
Outputs for a headphone set and for a pair of loudspeakers3
Easy-to-connect detachable terminal block connectors
A MUTE button to block out the sound
To achieve the best performance:
Connect only good quality connection cables, thus avoiding interference,
deterioration in signal quality due to poor matching, and elevated noiselevels (often associated with low quality cables)
Avoid interference from neighboring electrical appliances and position
your Kramer 904 away from moisture, excessive sunlight and dust
