Using the Leak Stereo 230 Integrated Amplifier is easy. First, connect your power cord to start it up. You can use the remote control to operate most functions. Connect your audio sources like a CD player to the analog RCA inputs or use the digital inputs such as HDMI ARC for high - quality AV connections. If you have a turntable, use the dedicated MM phono stage. For headphones, just plug them into the front - panel output. The amplifier will go into auto - standby mode after 20 minutes to save power. When it comes to maintenance, keep it in a cool and dry place. Avoid exposing it to dust and moisture. Clean the exterior with a soft, dry cloth. Don't use abrasive cleaners. Also, make sure the ventilation is good to prevent overheating. If you have any issues, check the connections first and refer to the user manual.
