MADA 2000

     The MADA-2000 eliminates the necessity of a lectern congested with a multitude of unsightly microphones that clutter the sight lines to the speaker. The Media Audio Distribution Amplifier is an audio mixing & distribution amplifier that is capable of supplying audio to reporters and sound cameramen at press conferences. The amplifier/mixer portion of the MADA-2000 provides two (2) microphone and one (1) line inputs which in turn feed the mixed signal to ten (10) fully insolated microphone or line level outputs. Each output is equipped with assorted standard connectors assuring easy access by the media. Other uses include: "on locations" recording, interfacing large audio systems at conventions, and isolating signals in applications where AC ground currents might present problems. The MADA-2000 features up to 60db of gain… low output noise (-90db)…low distortion (less than .25% THD at full rated output) and flat frequency response (+/- 0.5db 24-18kHZ). The MADA-2000 amplifier is self-contained with it’s own power supply and features differential balanced inputs with Op-Amp transformer isolated outputs. Isolation between outputs is well over 100db. All outputs, including headset monitoring jack, monitor level control and Bar LED level indicator are located on the front panel. Each of the ten (10) outputs are independently selectable to line or microphone level with each having selectable ground isolation to solve ground current problems. The rear panel contains XLR input connectors, phantom power control, mixing level controls and LED system level indicators. Link In/Link Out connectors are also mounted on the rear panel, enabling the user to cascade MADA-2000s to allow for multiple input and outputs. The MADA-2000 is designed for standard EIA 19" rack mounting and requires 3.5" of vertical rack space.
