2. The input signal can be equalized in high, low and 7 segments;
3. The input signal is divided into high-frequency and low-frequency two-way signal output, the cut-off frequency of high-pass and low-pass can be adjusted, and all of them have elevated, low frame and 7-segment parameter equalization processing;
4. All parameters can be modified, stored and called out by connecting computer with software.
3. Main parameters
4. Function introduction
<1> Volume adjustment: through the volume knob, you can adjust the output volume. Adjust anticlockwise to decrease the output volume, and clockwise to increase the output volume
<2> USB interface: USB interface is used to connect hy120 to computer. After connection, hy120 Pro software can be used to adjust relevant parameters of hy120.
<3> Input signal selection: music or microphone input signal can be selected through signal selection switch. When the selection switch is in the pressed state, the microphone signal input is selected; when the selection switch is in the release state, the music signal input is selected;
<4> Input signal indication: hy120 uses green and red indicator lights to indicate the currently selected input signal. When the green light is on, it means that the currently selected input signal is a music signal; when the red light is on, it means that the currently selected input signal is a microphone signal;
<5> Pressure limit indicator: the pressure limit indicator includes input pressure limit indicator, low frequency pressure limit indicator and high frequency pressure limit indicator. When the input or output voltage exceeds the set value, the corresponding lamp will be on;
<6> Power amplifier protection indicator: used to indicate the current protection status of power amplifier. When the power amplifier protection indicator is on, it indicates that the power amplifier is in the protection state.
<7> Music / microphone input interface: for signal input. You can use xlr3 connector (XLR 3-pin male) to access audio signal, or use 1 / 4 "(6.3mm) TRS connector (commonly known as big three core) to input microphone signal.
<8> Power supply: hy120 adopts ± 15V analog power supply, which is output by - 15V, GND and + 15V pins.
<9> Output signal: the output signal includes a low-frequency signal and a high-frequency signal, which are respectively output by low and high pins.
<1> Channel selection: control channel selection, input channel, low frequency output, high frequency output, control interface, convenient to control the parameters of relevant channels.
<2> Parameter saving and retrieval: the basic functions include saving, transferring out, initialization, etc. Among them:
① save: save all parameters to hy120 after user-defined parameters;
② call out: call out user-defined parameters saved in hy120 to make hy120 work in user-defined parameter mode;
③ initialization: initialize all parameters of hy120 to factory settings.
<3> Language selection: select the language of hy120 Pro interface. Hy120 Pro is available in English, simplified Chinese and traditional Chinese;
<4> Connect / disconnect: connect / disconnect is used to connect or disconnect hy120 module. When selecting connection, if hy120 module has been connected to PC and correctly recognized by PC, hy120 Pro will read current working parameters of hy120 module, and can change corresponding working parameters of hy120 module by modifying a parameter value in the interface.
<5> PEQ parameter adjustment: modify the type, frequency, Q value and gain of a frequency point by changing the position of the frequency point;
<6> PEQ parameter display: display the current PEQ parameters of the selected frequency point, including frequency point type, frequency, Q value and gain.
<7> PEQ parameter reset: reset the PEQ parameters of all frequency points under the selected channel to the initial state.
<8> Input / output parameter setting: input / output parameters, including start-up level, start-up time, attenuation rate, input delay time, output phase selection, input / output gain control, etc.
