PRELIMINARY
The MBR series include two models: the 12 channe ls
MBR12FX (8 mono + 2 stereo inputs) and the
16 channels MBR16FX (12 mono + 2 stereo inputs) .
The main features of both models are the really
compact size, that allows for mounting in a standard 19” rack, using the optional adapters, the
complete endowment of signal sends and returns
and the practical configuration of the controls, that
result in a simple and immediate utilization.
They are fitted with a dual Montarbo stereo effects
processor, based on a powerful, latest generation,
56 bit DSP, that provide 2 x 205 high quality
programs, with an uncompromised sound quality
(thanks to the dual 24 bit conversion) mated wit h
unusual ease of use.
The great flexibility of these mixing consoles allows
them to be used both in live applications (thank s to
the internal effect and to the two mon itor sends,
both with a 3-band equalizer) and in recording o r
broadcasting studios (thanks to the channel’s direct
outputs, the four effect sends, the co ntrol-room
out and the stereo return).
In both applications, a really useful feature will be
the possibility of plugging-in an analog recorde r
or of using the practical USB interface to conne ct a
personal computer, used as a digital recorder/player, and of monitoring the master output or the PFL
via the headphone output with adjustable volume.
Both models are also available in the powered versions MBR12FXP and MBR16FXP, that incorporate a
dual channel Class-D power amplifier rated at
750 + 750 W EIAJ. The switch-mode power supply
results in a minimal weight, and the very high
efficiency minimizes the emission of h eat, thus
increasing the system’s reliability and prolonging
it’s working life.

The mono channels are fitted with both
balanced microphone (XLR, with phantom power) and line
(jack) inputs, with adjustable gain, insert IN/OUT jack,
channel direct output, low-pass filter, 3-band equalizer with semi-parametric MF
control, 4 AUX sends (two of which may be switched pre-post fade) , PAN control,
MUTE and PFL switches, PEAK level indicator and volume fader
The stereo channels are fitted with one balanced microphone (XLR) and two line
(jack) inputs, with adjustable gain, 3-band equalizer, 4 AUX sends (two of which may
be switched pre-post fade) , BALANCE control, MUTE and PFL switches, PEAK level
indicator and volume fader.
The L/R master outputs are fitted with volume faders and 12-segment level indicatore.
The AUX outputs are fitted with a 3-band equalizer, the EFFECT send may be used as
monitor sends. The effect returns may be routed independently to the master and
monitor outputs.
