MUSMYS / P-5000
Class A at the start.
Class AB power in reserve.
The P-5000 is a separate Class AB power amplifier for a system with a suitable preamplifier or compatible volume-controlled source. It offers balanced and RCA input specifications and selectable speaker output groups for planning a component-based stereo setup.


DESIGN & CONTROL
Built for its role.
Matched to your system.
- Balanced input impedance: 40k ohms; RCA input impedance: 20k ohms.
- Speaker output selection: Group A, Group B or Group A+B.
- Specified load range: 2-16 ohms. Confirm the combined load before using multiple output groups.
- Specified static power consumption: 50-400W. Allow ventilation around the amplifier.
- Use suitable upstream signal and volume control before connecting passive speakers.
UNDERSTAND THE OPERATING RANGE
80W in Class A.
400W of rated output.
The first 80W per channel into 8Ω, or 160W per channel into 4Ω, operates in pure Class A. Higher output enters Class AB. Rated output is 400W per channel into 8Ω and 800W per channel into 4Ω, as confirmed by MUSMYS.
