IMPORTANT PRECAUTIONS
WARNING
In order to protect your own and others’ safety
and to avoid invalidation of the warranty of
this product, please read this section carefully
before operating this product.
•Read all documentation before operating your equipment.
•Retain all documentation for further reference.
•Mains voltage must correspond to rear unit label.
•Damages caused by connecting to improper AC voltage are
not covered by any warranty.
•Always operate the unit with the AC ground wire connected
to the electrical system ground. Precautions should be taken
to avoid equipment faulty, improper or inefficient grounding.
•After connection to power supply Standby LED is lit, showing
that some components inside are already powered.
•Make sure the signal is correctly connected to amplifier input
channel following current input mode.
•Please turn off the power switch when extracting the power
cord and signal cable, or adjusting the input mode switch.
•In order to split one signal to more than one amplifier, we
suggest to use a signal distributor.
•In typical use, please set the volume to -0dB position.
•If you need to supply power to more than one unit power
amplifiers, to eliminate the big surge current interference
to electricity net, and preventing the voltage fluctuate
abnormal when simultaneously switching on the amplifiers,
we recommend you use the sequence power procedure.
•Do not obstruct the air entrance and exit ports.

LM 260
INTRODUCTION
First of all, thank you for choosing a product FiveO by Montarbo®. This line of products has been designed for those who
want to set-up their user friendly audio sound system with excellent performances and outstanding value. Furthermore, we
manufacture all FIVEO products to assure you many years of satisfying and reliable operation.
Your LM 260 Loudspeaker Management processor, which perfectly suits the needs of stage, bands, rehearsal rooms and
even recording studios applications. Please, in order to enjoy each feature of your new processor thus achieving the best sonic
results, take a few moments to carefully read these instructions.
For further information about your microphone, please check our website www.fiveo.it, or send an email to: mail@fiveo.it
FEATURES
Your LM 260 Loudspeaker Management processor has been designed to successfully work in most demanding live and
studio applications. LM260 provides your several processing devices for your sound system. The first unit is a digital crossover,
allowing you to choose dividing frequencies for each way of your sound system, with slopes up to 24dB/Oct. by Bessel,
Butterworth and Linkwitz-Riley filters. The delay line allows you to align the emission point of each driver. The powerful 10band parametric equalizer allows you to make frequency response fine adjustments to perfectly tune each output of your
sound system in any venue. Furthermore we provided you also a useful phase switch and a limiter section to avoid amplifiers
overload.
Versatility, reliability and toughness will make LM 260 your faithful sound-mate for years...

SOF T WA R E USE
A USB I/O Type B (square) port is provided for upload/download presets to computer. Please, check the software pages to have
an easier and faster control over your LM 260.
INSTALLATION
Be sure that there is enough space around the unit to comfortably work and even for cooling purposes, to avoid over-heating.
Don’t place your processor on high-temperature devices such as power amps or radiators. LM 260 is connected to the
mains via the supplied cable. First connect the cable plug to the mains, then turn on the processor.
Please note that all units must be properly grounded.
For your own safety, you should never remove any ground connector/device from electrical devices or power cables, or make
them inactive. Please ensure that only qualified people install and operate the mixing console.
OPERATIONS
With your amplifiers turned off, start making connections. Using XLR cables connect balanced line level sources to LM 260 inputs, and
LM 260 outputs to amplifiers inputs. Turning on your LM 260, the last used preset is loaded but for a short time all LM 260 outputs
are set to MUTE. It’s a safety feature to avoid problems to connected sound systems, particularly when the levels are set to the maximum.

TIPS
We strongly suggest you to avoid exposition to loud music for prolonged periods, you risk to seriously damage your hearing.
It’s a good idea to check all the cables in your warehouse before departing, as well as carrying with you spare cables for any
emergency.
In order to prevent switch-on thumps, and subsequent drivers damages, please keep in mind the first audio lesson: amplifiers
must be turned on last, amplifiers must be turned off first! In order to keep the front panel clean, please scrub it with a soft
fabric just moistened with water. Don’t use solvents, which may corrode the front panel printing and paint.
Before activating your sound system, please carefully check mains grounding. Otherwise you could have hum or other
unpleasant noise. We suggest you to regularly inspect audio INPUTS level indicators. In this way, you can immediately detect
any abnormal level setting, making a fast reduction of input levels you can avoid inputs overloads.
Be careful using LM 260 extremely boosted EQs and LEVELs; such operation could overload the amplifiers inputs! So, we
suggest you to use the EQ to emphasize sound nuances and details, even cutting EQ on other bands! If the output CLIP LED
of any band is continuously lit, please check all the settings (LEVEL, Eqs, etc.) for that band; keeping in mind your settings,
you can operate in a fast way to reduce output levels thus avoiding amplifiers input overload.
