Supply & fixing of ceiling mount loudspeaker shall be a 2-way coaxial type equipped with a 5 1/4 inch low frequency driver combined with an 1inch mylar tweeter and fitted with a line transformer allowing it to be used on 100 Volt distributed line systems. It shall have an RMS power handling of 30 Watt with a maximum power handling of 60 Watt and the frequency response (±3 dB) shall range from 60 Hz to 20 kHz. The sensitivity shall be 87 dB when measuring with an input signal of 1 Watt at a distance of 1 meter, while the maximum continuous sound pressure level shall be 102 dB. The nominal dispersion shall be a 145 degree conical coverage pattern at -6dB (average 100 Hz - 10 kHz). The loudspeaker shall fitted with a multi-tapping line transformer with tappings for 6 Watt, 3 Watt and 1.5 Watt including an 8 Ohm bypass. Fast and smooth connection of the system shall be possible using a Fast-con TM multi-tapping connector. The speakers frame shall be constructed in high quality ABS material and the front shall be finished through a borderless and finely perforated steel grill. Including all taxes Make: Sennheiser Audac CIRA524/W / ClearOne/ Equivalent

Supply & Fixing of energy efficient and compact quad channel Class-D power amplifier, containing four independent controllable amplifier channels with an output power of 4 x 100 Watt. Bridging the outputs two-by-two shall be possible, merging their power to 200 Watt while an integrated (selectable) active crossover network shall be implemented to apply high-pass and lowpass filters to the channels, creating a sub / top configuration for a stereo system with bass cabinet.The construction must be transformerless using Class-D amplifier technology and powered by a switching power supply. Each channel shall have integrated circuitry to protect against short-circuits or mismatched loads and over-heating. The amplifier must be convection cooled so that maintenance can be kept to a strict minimum. An automatic signal detection circuit shall be implemented, witching the amplifier to standby mode when no input signal is detected. The energy efficiency levels shall comply with energy-star and other international energy and environmental requirement standards. The front panel shall contain an AC power switch accompanied by a blue power indicator LED and channel operation indicator LED’s. A green signal LED’s indicates the presence of an input signal and it’s level exceeding the -20 dB level, a clip LED indicating the channel operation at maximum level and a protection LED indicating any fault detected shall be provided for each channel. All connections shall be made on the rear panel of the unit. The signal inpu connections shall be balanced and performed using XLR connectors. The output connections must be fitted with terminal block connectors.incliding all taxes Make Sennheiser Audac EPA104/ ClearOne/ equivalent.
