MTX MONITOR PREAMPLIFIER FROM FUNK TONSTUDIOTECHNIK

As I asked my friends what they think about Funk MTX Monitor, they told me they should have known it before or now they should throw away a half of theirs studio equipment. This device has incredible functionality and very reasonable price. Parameters you can see below. Unfortunately you can not compare it with other devices because there is no other company which publish such informations







The MTX-MONITOR.V3b-1 Precision Monitor Router is the successor to the proven MTX-Monitor.V3a, which have both seen regular use as neutral reference units in magazine tests. State-of-the-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 optimizes crosstalk attenuation and phase response. This convenient monitor amplifier features top-of-the-line signal processing and is one of the most level-accurate analogue pre-amps available today. Areas of application are radio, TV and professional mastering studios, as well as high-end audio systems.

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.

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 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 equalizers, 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.



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 anodized black or blue. Hi-fi versions are delivered with a 435 mm housing, without front 19" rack-mounting holes. Reinforced 5 mm front panels are available in silver or anodized black; studio versions have black, silver or white front panels.

REMOTE CONTROL

The remote controller 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. 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).

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.
