    If any damage is visible contact your dealer. • Keep all original packing. • Never use this product in the vicinity of water. If the M-300 were to get wet, it could kill you by electrocution. • The output power of this amplifier can generate enough sound pressure levels from your speakers to cause PERMANENT hearing damage to you and anyone else who is close to it.
  • Page 4 Switch power off and press reset button on back panel. 6. DC Output Protection. The M-300 is a DC coupled design that offers the best performance. If a fault occurs internally in the amplifier it will shut down and protect your speakers from any lethal DC current.

    2. INPUT LEVEL SENSITIVTY CONTROL CHANNEL ONE. Just as no two basses are alike, the same goes for players with different styles and technique. This is a fine-tuning adjustment (+/- 10dB) to get the precise match between your instrument and the M-300.
  • Page 6 3. 5-BAND GRAPHIC EQUALIZER CHANNEL ONE. This is a dedicated bass instrument equalizer designed to give you precise tone control of your instrument. It is a very powerful tone processor, which with a little understanding will give you the greatest benefit in getting the most out of your instrument and sound system.

    PJB cables. Matching the M-300 to PJB Loudspeakers The M-300 will work on loudspeakers from 16Ω to 3Ω with ease. It is not recommended to run on 2Ω loads at full power, during the hotter summer months. The amplifier needs a constant flow of cool air to maintain an optimal working temperature.
  • Page 10 dimensions heavily influence them when the walls reflect the sound waves, causing them to collide by adding together or canceling each other out. This causes some fundamental notes (the ones you feel more than hear) to ring out louder than others and some note not to be heard at all.
  • Page 11 Although the M-300 can work on speaker loads down to 2Ω, it is not advisable to do so on a continual basis at high power levels, since there is more heat generated. If the weather is hot, there may not be enough cooling from the internal fan so the amplifier could momentarily cut out as the amp’s heat protection circuits kick in.
  • Page 12 A cheap amplifier may be designed to last a few years before it dies. It may cost more than its worth to give it an overhaul. In essence you get what you pay for. Your M-300 is built to last for a very long time running day after day at continuous high power levels.
  • Page 13 Use a cover or road case when transporting or storing the amplifier. The M-300 was built to be as rugged as possible. However you should handle it with care. Keep it away from moisture, heat and dust. Clean with a soft damp cloth such as a moist towel.
