MAINTENANCE
The GOLDMUND SR150 amplifier usually requires no maintenance.
To clean your SR150 use a very soft, clean, damp cloth to avoid scratching the surface.
Dampen with water or a mild detergent solution. Avoid abrasive or harsh cleansers (eg.
products containing sodium carbonate). Always turn the power off before cleaning your
amplifier.
TECHNICAL DATA
POWER
• Nominal power before clipping: 2x200 W RMS (2 - 8 Ohms). 150 W RMS (1 - 16 Ohms).
• Maximum power : > 400 W RMS (3 Ohms).
• Maximum voltage : 55 V peak. - Maximum current : > 15 A peak.
These values are for both driven channels.
FREQUENCY RESPONSE
These figures are valid for the circuit alone, at any level between 0 and nominal power.
