Mark Bass MB58R COMBOS P Series User manual

The MB58R series is a further example of how Markbass is always one step ahead in innovating
using state-of-the-art technologies. Once again Marco De Virgiliis with his pioneering soul has ma-
naged to create this new series of products which, with the use of custom components born
thanks to years of experience and research Markbass and the use of revolutionary materials with an
eye to the future and the evironment, has really nailed the tone and power versus portability issue.

7) Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions;
8) Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including
ampliers) that produce heat;
9) Do not defeat the safety purpose of the polarized or ground-type plug. A polarized plug has two blades with
one wider than the other. A grounding type plug has two blades and a third grounding prong.
The wide blade or the third prong are provided for your safety. If the provided plug does not t into your outlet,
consult an electrician for replacement of the obsolete outlet;
10) Protect the power cord from being walked on or pinched, particularly at plugs, convenience receptacles, and the
point where they exit from the apparatus
11) Only use attachments/accessories specied by the manufacturer;
12) Use only with the cart, stand, tripod, bracket, or table specied by the manufacturer,
or sold with the apparatus. When a cart is used, use caution when moving the
cart/apparatus combination to avoid injury from the tip-over (and Fig 21 DU Tipping Cart Symbol).
13) Unplug this apparatus during lightning storms or when unused for long periods of time;
14) Refer all servicing to qualied service personnel. Servicing is required when the apparatus has been damaged in
any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the
apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped;
15) “WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS APPARATUS TO RAIN OR
MOISTURE AND OBJECTS FILLED WITH LIQUIDS, SUCH AS VASES, SHOULD NOT BE PLACED ON THIS APPARATUS”.
16) TO COMPLETELY DISCONNECT THIS APPARATUS FROM THE AC MAINS, DISCONNECT THE POWER SUPPLY CORD
PLUG FROM THE AC RECEPTACLE;
17) THE MAINS PLUG OF THE POWER SUPPLY CORD SHALL REAMIN READILY ACCESSIBLE.
18) In case of voltage selector make sure the switch on the rear panel is on the correct voltage before connecting it to
the AC power, and the fuse is the right value for that voltage (This selector is not available on the 100V version).
Please change the voltage/fuse values label located near the voltage selector matching the voltage/fuse values
when you need to change the voltage of the apparatus.
19) “WARNING: THIS APPARATUS MUST BE SECURELY ATTACHED TO THE FLOOR OR WALL IN ACCORDANCE WITH
INSTALLATION ISTRUCTION. TIPPING, SHAKING, OR ROCKING THE MACHINE MAY CAUSE INJURY OR DEATH.”

THERMAL PROTECTION
SYMPTOM The amp gets hot and shuts down.
PROBABLE CAUSE The amp is overheated, either as a result of inadequated ventilation or damage cooling system
fan. When the amplier cools down to a safe level, the amp will automatically restart.
SUGGESTIONS Please verify that the fan is working properly, and that the cooling system ports are not obstructed.
CURRENT PROTECTION
SYMPTOM The amp turns on, but there is no signal coming from the speaker/s.
PROBABLE CAUSE Low impedance load (minimum impedance for Markbass amps is 4 ohms), or a bad speaker cable.
SUGGESTIONS Please verify the impedance of the speaker/s connected to the amp. Note that two 4 ohm cabinets, or an 8
ohm and a 4 ohm cabinet, will result in an impedance below 4 ohms.
Please check the speaker cable/s.
After checking these two things, please turn the amp off and turn it on again.
If the troubleshooting steps outlined above do not solve your problem, please contact your Markbass distributor/dealer for service
information.
