XLS202: 8 Ω 200W 4 Ω 300W 8 Ω 600W XLS202 contains a series of outstanding features and excellent reliability. Each channel on the high-pass filter selected by the third gear, including (30Hz/15Hz / off). For the full-frequency speakers, you can choose 30Hz or 15Hz, is used to prevent unwanted ultra-low frequency signals overload woofer. For the subwoofer, you can turn off. Metal package output devices, although it than other manufacturers use more expensive plastic output devices, but its high efficiency and reliability. Advanced equipment to detect the power curve for each device and peak power handling capability, and then brush selection and matching. All steel chassis with rugged, and configure the fan to avoid excessive force and efficient heat accumulation. Input Sensitivity XLS 202: 0.725V at full capacity allocated to the 4Ω load Frequency response (from 20Hz-20KHz) XLS 202: ± 0.75dB Phase Response (at 1W pm) XLS 202: When in 10Hz, -10 ° When in 20KHz, +19 ° SNR (20Hz-20KHz) XLS 202:> 100dB (A weighted, at full load operation) Total harmonic distortion (THD) XLS 202:: <0.15% (at full load output, from 20Hz-1KHz) Intermodulation distortion (IMD) (4: 1 pm at 60Hz and 7KHz) rated power, the output value of-40dB when XLS 202: <0.3%
