Description:
Stereo, Class A integrated amplifier with push-pull circuit. The rated output power of the device is 20 W maximum per channel. The outputs on the rear panel can be connected to speakers with a nominal impedance of 8. The design of the power amplifier output transformers allows the amplifier to also be connected with speakers with a nominal impedance of 4. This leads to a slight deviation from the indicated parameters. in the technical data sheet.
On the front panel, the volume control potentiometer and the input selector are connected to the same axis. The indicators that inform about the actual status of the amplifier are also located on the front panel. It can be monitored if the device is ready to go (if so, the LED next to the volume control changes from red to white). The user is also informed about the actual position of the input selection unit. The amplifier is made of 1.5mm thick solid polished stainless steel sheet.
