Product Characteristics
▼ 4 in and 4 out can specify any input to output. ▼ The input interface adopts a universal socket, which can be connected to XLR head or 6.35 plug A set of stereo line input lotus interfaces can be specified to any output interface, with independent mute and adjustable volume. ▼ Two sets of lotus output interfaces can record or output to other devices ▼ Each input has options for gain, feedback, equalization, voltage limit, 48V phantom power supply switch, and sensitivity of 0 6 12 18dB. ▼ Use a 2.7 inch large screen display, which displays the channel volume, frequency shift position, input and output signal level, current mode, and panel lock ▼ The system can set panel locks to prevent work state disorder caused by misoperation. ▼ 24BIT high-performance A/D and D/A conversion, which is based on a 24 bit floating point DSP engine, 48KHz sampling high-speed floating point operation, and a powerful digital Audio signal processing platform ▼ Built in one button direct/feedback mode that can be converted and automatically scanned for howling points and suppressed, which can increase the gain by 6-15dB. The fully automated operation mode eliminates manual debugging. ▼ The built-in noise gate function can suppress weak system noise interference, filter out background noise in the on-site environment without affecting the high-quality transmission of voice signals, and improve the clarity of voice signals. ▼ The slope of the built-in variable high/low pass filter can be set, where Bessel, Butterworth Linkwitz Ryley are set to 12dB, 18dB, 24dB per Octave band to limit the voice frequency response, ▼ Built in compression function, eliminates feedback while also expanding vocal dynamics. ▼ Built in 15 section PEQ equalizer adjustment. ▼ Each input channel is equipped with five frequency shift options, which are used in conjunction with balanced EQ to achieve outstanding anti howling effects. ▼ Each input channel can have up to 9 notch filters, and dynamic or static notch filters can be set. The response time can be set at 3 speeds, fast, medium, or slow. ▼ Support 10 sets of scene preset functions, which can be called through the panel and computer PC software
