MB-1200 Mono Block Power Amplifier, Front Panel

6	MB-1200 Mono Block Power Amplifier

Thank you for purchasing the Fender® MB-1200 Mono Block Power Amplifier. We designed this professional power amplifier to complement our TBP-1 Tube Bass Preamp (or any other reputable manufacturer’s preamp). The MB-1200 is a "mono-block" power amp. This means there is one single power source delivering ALL 1200 WATTS of power (no bridging needed). You can use one MB-1200 to power a 2 Ohm load and deliver 1200 watts of crushing bass power. Should you need more power, you can slave multiple MB-1200’s together to give you enough bottom end to shake any stage!

•1200 Watts into 2 Ohms (800 Watts into 4 Ohms)

•Both Speakon® and 1/4" outputs offer maximum flexibility

•Power amp pass through allows you to chain multiple MB-1200’s together

•Blue "power-on" light bar doubles as a signal strength meter to indicate power usage

Thank you for choosing Fender®

Front Panel

A. VOLUME – Adjusts overall amplifier loudness in conjunction with any level controls found on a connected preamp.

B.DUAL-PURPOSE LIGHT BAR – The entire length of the bar glows blue when receiving power. The numbered LEDs behind the light bar indicate signal strength presented to the power amp section, calibrated in dB (decibels) before clipping. The bargraph is accurate for all speaker loads. The CLIP LED will flash red when the amplifier clips. The PROTECT LED will glow yellow if the thermal protection circuit becomes active

to protect the amplifier from over-heating. Should this happen, check to see that all front vents and the rear fan openings are clear from any obstructions. Maintain proper ventilation clearances. (The bargraph will still operate in thermal shutdown mode indicating that any signal source connected to the amplifier is still operating properly.)

C.POWER – Switches the unit on/off as indicated by the light bar glowing blue.

3) Lift the MB-1200 into position and provide temporary support until all corners are attached.

4) Bolt the MB-1200 front panel tabs to the front rack rails.

5)Slide the adjustable brackets {J} to fit the rack, then attach with bolts through the rear rails {I} as shown.

6)Tighten all bolts securely.
