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 dbx 520 will help you expertly tame the excessive sibilance often found in vocals and other high frequency dense material. Based upon the legendary dbx 902, the dbx 520’s unique features make it possible to achieve an exact amount of de-essing regardless of variations in signal levels. The 520 allows you to create brilliant, crisp vocals without sibilance!
With its modular 500 Series based design, the dbx 520 examines the differences in dB between the high frequency and full-bandwidth portions of a signal, allowing de-essing of signals which change in level by as much as 60dB. It features a Frequency Control with range from 800Hz to 8kHz, Gain Reduction Metering and a De-essing Amount Range from 0dB to 20dB.
Control vocals, drums, percussive instruments and problematic material/reverb combinations with the dbx 520! |
An elegant slim-line device contains all the functions required by a system for distributing different musical programmes in homes for multi-room sound systems and commercial premises.
Three different musical programmes and one for paging can be transmitted in five mono zones, or alternatively four zones, one of which is in stereo. It is also possible to extend the number of zones to ten using a simple connector to interlink two systems. The system has five amplified 20 W / 4 ohm outputs. For each of the five zones, a direct auxiliary input is available for connecting sources such as CD players or mixers to be used exclusively for one zone/room.
The back-lit display and function keys make it possible to access all the menus for configuring and adjusting the system: Volume, Tone, Loudness, Output settings, VOX.
