System overview
The mixer amplifier is equipped with an inbuilt music source, which can provide hours of uninterrupted music either through Bluetooth streaming or USB pen drive. It is supplied with an IR remote control for controlling the music source. The unit features four mic/line inputs, 1 BGM and operates in a single zone. To ensure optimum performance, there are no moving parts, such as hard drives that can fail or wear out. The unit has a limiter circuit and provides an audio insert feature to use as a pre/power amplifier. The VU meter gives an output level indication. 

Power The mixer amplifier has an output power of 240 W. This power is directly available on 100 V constant voltage connections and on a low impedance connection for a 4-ohm load. Moreover, the amplifier has a separate 100 V call-only output channel for addressing areas where only priority announcements are required. The call-only output can also be used for 3-wire remote volume control override.

u Better discussion control u Controls up to 50 Discussion units u Built-in audio recorder and amplifier u Audio interfaces for connecting external audio equipment
Recorder and Amplifier The CURA has a built-in recorder, the user needs to plug in either USB pen drive or a SD card, to record the meeting, which can be used to playback the recorded Meeting. The Controller is also equipped with a 30 Watts power amplifier, by which the user can connect additional loudspeakers for sound reinforcement.
Audio Interfaces The CURA can be interfaced with different types of device like a sound reinforcement system, external microphones and an external music player. The headphones output on the front of the CURA can be used by a secretary for taking the minutes of the meeting, the headphones output also has a volume control knob to adjust the volume of the headphones. To support external participants (during town-council meetings, for example), extra microphones in any style (wired, wireless, hand-held or podium) can be connected to the system through mic inputs.
