Fender MB-1200 - Manual (Page 6)

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.

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®
