CX-Q 4K4 A&E Specs The power amplifier shall be a four-channel network-processing device that is designed to operate exclusively with a QSC Q-SYS ecosystem on a Gigabit Ethernet network. The amplifier shall be powered by a universal switch-mode power supply that supports operation at any AC voltage from 100 to 240 V at 50 or 60 Hz. The power supply sha2ll have power factor correction (PFC) to make the current flow nearly sinusoidal and analogous to the voltage waveform. The amplifier shall offer multi-stage sleep modes to automatically reduce AC power consumption during idle time. The amplifier shall be cooled by forced air, with the intake at the rear and exhaust at the front. The fan speed shall be thermally controlled and also shall be visible in units of revolutions per minute (RPM) on the amplifier’s front panel as well as on its network control panel. The amplifier shall utilize a class D output circuit topology with four individual channels (A through D) providing up to 4000 watts (maximum short term) total power. The amplifier outputs shall utilize a technology called FlexAmp™, which provides up to 2000 watts of power to each pair of channel outputs, to be apportioned between themselves as needed. The outputs shall also utilize Flexible Amplifier Summing Technology™, which allows multiple channel outputs to also be combined in series (i.e., bridged) and/or parallel. The amplifier shall be configurable via Q-SYS, including arranging the output channels as single units as well as in various bridged and parallel combinations. The amplifier’s audio signals shall originate in the Q-SYS ecosystem and shall also be configurable in Q-SYS. The power amplifier shall have four balanced analog mic/line audio inputs that stream digital audio data into the Q-SYS ecosystem in the form of Q-LAN data delivered via the network port. The impedance of each input shall be greater than 8 kΩ balanced or 4 kΩ unbalanced. The power amplifier shall meet the following performance criteria: typical distortion (into 8 ohm loads) of 0.02% to 0.05%; maximum distortion (4 to 8 ohms) of no worse than 1%; a frequency response (into an 8 ohm load) of from 20 Hz to 20 kHz at ±0.25 dB; noise at -104 dB (A weighted, with output section muted); maximum gain of 35 dB (on 1.2 V setting); IHF damping factor of greater than 100. Channel muting and gain shall be controllable via the amplifier’s front panel controls or the Q-SYS ecosystem. Changes made either way shall immediately reflect in the other as well. The amplifier shall indicate network status and monitoring, including faults. The front panel shall offer a summary of fault and error conditions. The amplifier shall have output load monitoring on each output. The load monitor shall have the range to detect and calculate impedance of conditions including short circuits, low impedance loudspeakers, and lightly loaded 70 V and 100 V lines with impedances as high as 1 kΩ. The load monitor shall report the calculated load impedance on each channel via the front panel and the Q-SYS network. The amplifier front panel shall feature LED metering of all eight inputs and eight outputs, a 400 × 240 TFT color display, navigation buttons, an LED power button/indicator, a fault indicator, a control knob, and cast aluminum handles. The amplifier rear panel shall feature dual RJ-45 jacks for connecting to the Q-LAN network, enabling integration into the Q-SYS ecosystem for bi-directional passage of digital audio, control signals, and status monitoring data. The rear panel shall provide four 3-pin Phoenix connectors for the balanced analog audio inputs (for mic or line signal levels), and four touch-proof Phoenix connectors for connecting loudspeaker cables to the channel outputs. The amplifier rear panel shall also provide eight GPIO terminals that extend Q-SYS control to or from external devices. The amplifier shall be 3.5 in (89 mm) high, 19 in (482 mm) wide, and 16 in (406 mm) deep. The amplifier shall have a net weight of 25 lb (11.3 kg). The multi-channel system-processing amplifier shall be the QSC CX-Q 4K4.
