Because the M300/S300 runs cool, it can be placed in many system locations without compromise. We do not recommend placing weights or other objects directly on the M300/S300. This may scratch or mar the chassis finish. Do not use harsh chemicals when cleaning the outside of your M300/S300. IMPORTANT! Make all connections before powering your unit! The e.One M300 and S300 are mono and dual-mono audio power amplifiers that deliver up to 150 watts into 8 ohm loads and 300 watts into 4 ohm loads.
Never Connect Either the Positive or Negative Speaker Output to Any Ground Contact! Connecting any Speaker Output on the M300/S300 to Ground will cause the amplifier to go into protection and could damage the amplifier and void the warranty. • Power Switch: Power is on when the switch is toggled to the I position and off in the O position. • Do not connect both XLR and RCA cables to the inputs! • IEC power cord jack: Connect a heavy gauge power cord from this jack to the wall power supply.
• In case there is hum or ground noise, check that the RCA/XLR switch is in the correct position for the type of connection being used. • Ensure that the preamplifier or any source components are not producing hum by setting the preamplifier to a MUTE or Standby setting. • The design of the M300/S300 reduces the chance for ground loop induced hum, but we still recommend using shorter interconnect cables to the preamplifier.
