MUSMYS / E-406
A clear role.
A dedicated power stage.
Build your system around a dedicated stereo power amplifier. The MUSMYS E-406 combines a Class AB output stage, balanced and RCA inputs, and dual front-panel meters in a substantial aluminum chassis. Its listed continuous output is 180W per channel into 8Ω or 320W per channel into 4Ω, specified across 20Hz–20kHz.
DESIGN & CONTROL
Built for its role.
Matched to your system.
- 24 high-power output transistors in the power stage.
- 850W copper-wound transformer and 320,000µF capacitor bank in the power supply.
- Independent left and right channel amplifier boards arranged symmetrically.
- Mechanical signal relays and independent speaker protection relays for switching and protection.
- Dual speaker output groups for bi-wiring compatible speakers. Confirm the speaker wiring requirements before use.
- Dual-meter display and aluminum chassis for a component that makes a clear visual statement in your system.
THE SIGNAL PATH
The right component.
In the right place.
Connect the E-406 to a suitable preamplifier or compatible source with volume-controlled outputs, then connect your passive speakers. Choose the input connection that matches your upstream equipment and confirm speaker compatibility before setup.
DIMENSIONS & PLACEMENT
Give your system room.
430 × 495 × 170mm (W × D × H). Net weight: 21kg.
Use a stable support with sufficient load capacity and leave clearance for connections and ventilation.

DELIVERY & AFTERCARE
A considered journey.
From us to your system.
Contact MUSMYS to confirm packaging, destination, freight charges and handling requirements.
- Select your voltage: choose the 110V or 220V version that matches your mains supply. Confirm local voltage and frequency before ordering.
- Plan the space: allow for the 495mm chassis depth, rear connections and clear airflow around the amplifier.
- Prepare your cables: a power cord is not included.
- Check import costs: duties, customs-clearance charges and local taxes are the buyer’s responsibility.
Frequently asked questions
Do I need a preamplifier?
The E-406 is a separate power amplifier. Use a suitable preamplifier or compatible volume-controlled source to control listening level.
Can I use balanced or RCA connections?
The E-406 supports balanced and RCA inputs. Match the connection to your upstream equipment; listed input impedance is 40kΩ balanced and 20kΩ RCA.
Which voltage version should I choose?
Match the 110V or 220V option to your local mains supply. If you are unsure about voltage, frequency or system matching, contact us before ordering.
