mXa-1502 Mixer-Amplifier Architect & Engineering Specs Electronic: The unit shall consist of a two-channel, multi-mode Class D amplifier capable of driving 2 Ohm loads at full power. Each channel shall have selectable output mode of Low Z, 25V, 70V, or 100V with a maximum rated output power of 150W per channel in all modes and will be bridgeable to deliver a single channel power output of 300W @4 or 8 Ohms. There shall be an automatic but defeatable sleep mode consuming <1W. A switch-mode power supply with active Power Factor Correction (PFC) shall auto-detect 100 – 240VAC mains and operate from 70 – 270VAC. The unit shall have a multi-channel, user-programmable DSP capable of mixing 8-mic/line inputs, plus 4 stereo line inputs into 4 independent outputs. The mic inputs shall each provide 48V phantom power, switchable per channel via software. Each Input DSP channel shall have up to six assignable DSP function blocks, which shall be arrangeable in any order by the user and which may include: Gain, VCA Gain, DCA Gain, Remote Gain, 10-band PEQ, 31-band graphic EQ, HPF, LPF, Compressor, Auto-Leveler, Brick Wall Limiter, Gate, Feedback Suppressor, Delay, Signal Generator & Meter. DSP functions for the stereo channels shall also be stereo. Each Input shall allow routing to up to four mixers, each of which provides: Gain, Meter, Auto-Mix & Ducker assignable to each input channel. The unit's Output DSP consists of four channels, each having six assignable blocks, also arrangeable in an order by the user and which may include: Gain, VCA Gain, DCA Gain, Remote Gain, 10-band PEQ, 31-band graphic EQ, HPF, LPF, Compressor, Auto-Leveler, Brick Wall Limiter, Gate, Ambient Noise Compensation, FIR Filters, Delay, X-Over (2, 3 & 4-way), Signal Generator & Meter. Each Output Channel shall allow receiving a signal from any one of the four mixers as determined by the user. The four Output Channels shall feed the two amplifier channels (AMP OUT 1 & AMP OUT 2) and the two AUX Line Out Channels (AUX OUT 1 & AUX OUT 2) respectively in a fixed configuration. The unit's DSP shall also incorporate an RTC (Real-Time Clock), which can be synchronized to an external clock source (such as a PC or NTP server). The unit shall have a built-in scheduler (driven by the RTC), which can be programmed by the user for various timed operations, such as: power-on/standby, preset recall, sub-preset recall, source select, channel mute/unmute & channel gain adjustment (+/-). The unit's DSP shall be managed by an internal web-server and database and controlled by a networked PC or tablet device which is browser-enabled. It shall therefore not be required that a separate software application be installed on a PC or other device, in order for the user to access DSP functions. Mechanical: The front panel shall have LEDs indicating Input Signal (green), Clip/Mute (Red), Current (Green) and Temperature (Yellow) for each power channel and will also have global LEDs for indicating the amp's Protect (Red), COM (Green), Disable (Yellow) and Sleep (Blue) modes. The front panel shall have four momentary buttons that may be user-programmed to perform preset recall or source-select functions. There shall also be a round momentary Power button with a white LED backlight to indicate the amp's "ON" status. The front grille shall be composed of high-impact resin and shall be perforated to allow proper airflow. The unit's rear panel shall have 8-Balanced Mic/Line inputs each with removeable 3.5mm Euroblock connectors and will also have 4-stereo unbalanced Line Inputs, each with dual RCA phono connectors. The unit will have two balanced line (AUX) outputs with removeable 3.5mm Euroblock connectors and two powered speaker outputs, which shall have 7.62mm Euroblock connectors. The unit shall have 8-adressable GPI & 2-GPO, 2-Amplifier Fault, 3-VC Remote, 1-Serial Data and 1-Amplfier Standby ports, all with removeable 3.5mm Euroblock connectors. There shall be a DIP-switch pair for each power amp allowing selection of amplifier mode (Low Z/25/70/100V). The unit shall be networkable and shall have an RJ45 100/1000BaseT Ethernet jack. The unit shall have a detachable IEC power receptacle capable of working with region appropriate power cables. The unit shall be housed in a 1U metal chassis, with front and side perforations to allow proper cooling from the variable-speed fans. The unit shall weigh <11.3 lbs. (5.1kg) and shall measure 19” W x 1.75”H x 14.54” D (483mm x 45mm x 369mm) and mount in a standard 19” rack. There shall be a five-year warranty for units purchased in the US. No other unit shall be acceptable unless all specifications represented herein are met or exceeded and submitted in writing by an independent testing agent. The unit shall be the Ashly mXa-1502 Mixer-Amplifier.
