2 Είσοδοι - 2 προενισχυτές (Μουσική - Ανακοινώσεις) / 8 Έξοδοι - 8 Τελικοί ενισχυτές για την διάδοση του ήχου σε 8 ζώνες
The MZU 2008 switching unit can be installed in 19” racks for selective voice/music switching in 8 audio zones, with the
possibility to increase the number of zones as multiple of 8, adding other MZU 2008 in cascade. Selection of the zones in which the music is to be interrupted and an announcement transmitted is carried out from the MBT 8008 control console.
Using the 8 "MUSIC” keys on the front panel, you can choose in which of the 8 audio zones to play the normal background
music and in which zones no music is to be played. The system can be configured in one of the following ways:
• a) the 2 inputs of the unit are driven by two amplifiers, one of which is dedicated to voice transmission and the other to music transmission.
The 8 outputs of the unit drive the 8 speakers of the 8 audio zones.
• b) the 2 inputs of the unit are driven by two signal preamplifiers, one of which is dedicated to voice transmission and the other to music transmission. The 8 outputs of the unit drive the 8 power amplifiers dedicated to sound diffusion in the 8 audio zones.

The MULTIGATE PRO XR4400 provides four frequency-selective expanders/noise gates in a single rack space. Each section comprises an ultra-fast gate, a program dependent expander, a filter section and precision meters indicating both threshold point and gain reduction.
The included side chain parametric filters allow the user to fine-tune control signals so that the gate reacts only when required. The Interactive Attack Control (IAC) circuit analyzes the program material to calculate the attack time of the gate. Separate hold and release controls offer additional flexibility. The XR4400 has a switchable operating mode for the gate and expander. With the MODE function off, the unit works in gate mode using an extremely fast attack time, thus preserving the transient details of the program material. In expander mode, the device analyzes the shape and dynamic contents of the input signal to calculate the control time parameters. The result is that vocals, instruments and complex mix signals can be cleaned up without audible clicks or other detrimental effects.
A couple function on the XR4400 provides a great deal of flexibility to link the expander/gate sections in a master/slave configuration.
