Logic System loudspeaker products are designed to be used with the LS8Q and LS12Q four channel power amplifiers. Made for Logic System by Powersoft, they feature sophisticated power supplies, powerful DSP processing and Dante® as standard, in a 2u package. The rugged construction and Neutrik® connectors, allow use in touring or installation applications. The PFC (Power Factor Corrected) power supply allows operation on standard mains voltages, anywhere in the world. Powersoft’s SRM (Smart Rails Management) technology ensures electrical efficiency by only delivering the full rail voltage when the signal requires it to, which also reduces power draw (and heat dissipation) to less than 34W when idling. The powerful DSP can work with a 48 or 96kHz sampling rate, via an internal sample rate converter. Low and high pass filters up to 48dB/octave, plus parametric, all-pass and shelving type IIR filters are available, as well as up to 2048 tap FIR filters on each channel. In addition, Raised Cosine filters are also implemented, which are particularly useful for system tuning, due to their wide and narrow band equalisation flexibility. Audio inputs are provided by analogue, AES3, Dante® and AES67. The integrated gigabit Ethernet switch allows connection via star or daisy-chain wiring. Control of the LS amplifiers via Armonia+ can also be performed over the same Ethernet network. Usefully, the LS amplifiers can be used as an “on ramp” for converting analogue or AES3 input signals to Dante® or AES67 for audio distribution over a wired Ethernet network. LS amplifiers can be operated directly from the front panel, via the large colour touchscreen display, or over wired Ethernet, via the Armonia+ application. The amplifiers come pre-loaded with Logic System presets, for plug and play operation. The LS8Q can deliver peak output voltages up to +/-155V, with the more powerful LS12Q able to deliver an even greater +/-180V to maximise system headroom, when driving Logic System loudspeakers. Power output for both models is shown in the table below for a variety of symmetric/asymmetric loads, plus bridging options.

Logic System扬声器产品设计用于LS8Q和LS12Q四通道功率放大器。它们由Powersoft为Logic System制造，采用2u封装，具有复杂的电源、强大的DSP处理和Dante®作为标准配置。坚固的结构和Neutrik®连接器允许在巡回或安装应用中使用。 PFC（功率因数校正）电源允许在世界任何地方的标准电源电压下运行。Powersoft的SRM（智能轨道管理）技术通过仅在信号需要时提供全轨道电压来确保电气效率，这也将空转时的功耗（和散热）降低到34W以下。强大的DSP可以通过内部采样率转换器以48或96kHz的采样率工作。高达48dB/倍频程的低通和高通滤波器，加上参数、全通和搁置型IIR滤波器，以及每个通道上高达2048抽头的FIR滤波器。此外，还实现了凸起余弦滤波器，由于其宽带和窄带均衡灵活性，这对系统调谐特别有用。音频输入由模拟、AES3、Dante®和AES67提供。集成的千兆以太网交换机允许通过星形或菊花链接线进行连接。通过Armonia+对LS放大器的控制也可以在同一个以太网网络上进行。LS放大器可以用作“入口”，将模拟或AES3输入信号转换为Dante®或AES67，以便通过有线以太网进行音频分发。 LS放大器可以通过大型彩色触摸屏显示器直接从前面板操作，也可以通过Armonia+应用程序通过有线以太网操作。放大器预装了逻辑系统预设，用于即插即用操作。 LS8Q可以提供高达+/-155V的峰值输出电压，而更强大的LS12Q在驱动Logic system扬声器时能够提供更大的+/-180V，以最大限度地提高系统净空。下表显示了两种型号的功率输出，适用于各种对称/非对称负载，以及桥接选项。
