MONITOR AMPLIFIER
The MTX-MONITOR.V3b-1 Precision Monitor Router is
the successor to the proven MTX-Monitor/MTXMonitor.V3a, which have both seen regular use as
neutral reference units in magazine tests. State-ofthe-art components further improve the signal
quality. New input stages provide a higher input level
and better dynamics, while an upgraded matrix
guarantees even lower distortion and optimises
crosstalk attenuation and phase response. This
convenient monitor amplifier features top-of-the-line
signal processing and is one of the most levelaccurate analogue pre-amps available today. Areas
of application are radio, TV and professional
mastering studios, as well as high-end audio
systems.
main output is balanced for +6 dBu level, while
the secondary output is unbalanced (0 dBu).
An unbalanced stereo measuring output is used
for signal monitoring (switches with the
monitoring source). This is used for connecting
equalisers, stereo imagers or other audio devices.
Speakers and headphones have separate volume
controls.
A red clipping LED reliably indicates potential
distortion across the entire signal chain.
One or several of the eight inputs may be selected
as recording signals (record routing), independent
of the monitor signal selection.
The MTX-Monitor.V3b-1 is equipped with a precision
power supply with separate paths for analogue and
digital circuits.
With its dynamic range of more than 124 dB, its
excellent frequency and phase response ranging from
below 0.3 Hz to more than 1 MHz, as well as its
extremely low non-linear distortion of typically
0,0001% (-120 dB) in the all-important midrange, it
allows users to neutrally judge any selected signal
source. VCAs have been left out completely for
quality reasons. The audio matrix, the panning and
volume controls, and the majority of monitoring
functions in the audio path are non-contacting. This
guarantees a high degree of reliability and stability
for all audio parameters.
It features inputs for four balanced (+6 dBu) and
four unbalanced stereo signals. The levels of all
unbalanced RCA inputs and outputs can be
adjusted internally.
All functions are available for remote control. A
cable remote is available as an option.
All Neutrik XLR and RCA audio connectors are
terminated with gold pins.
The MTX-Monitor.V3b-1 is available in several
versions and with a wide range of options. The
front panel is available with a white coating, or
anodised black or blue. Hi-fi versions are delivered
with a 435 mm housing, without front 19" rackmounting holes. Reinforced 5 mm front panels are
available in silver or anodised black; studio
versions have black, silver or white front panels.
The usual monitoring functions, such as -20 dB, mute
left/right, mono, phase, left minus right, speaker
mute, balance, etc., are switchable. It is possible to
sum any desired combination of inputs. This function
may be switched off. External dimming is optional.
The unit features two selectable stereo outputs for
connecting power amplifiers or active speakers. The

MTX-MONITOR.V3b-1, hi-fi version, black
REMOTE CONTROL
The remote controler is delivered in a tabletop case.
It allows to select between eight analogue sources or,
in conjunction with a digital router (FUNK PAS-8, or
AMS-2 DAR for AES/EBU signals), the simultaneous
selection of eight digital sources. Monitoring and
recording source are selectable individually.
The standard version of the MTX-Monitor.V3b is
equipped with remote control and digital router
connectors (AMS-2-DAR or PAS-8) at the back
panel.
If a digital source is selected and the DIGITAL function
is enabled, the analogue monitoring router switches to
input 1. If a D/A converter is connected here, it is
possible to toggle between digital and analogue source
signals without having to switch the analogue matrix.
The remote control cable is available in lengths of up to
50 m (default length is 8 m).
