2.6 Parameter Description

Input Gain: used to compensate level diﬀerence between various input sources, especially those with lower input level, for overall level consistency.
Volume Mixer: used to send signals from microphone or music or both to outputs.
HPF (High-Pass Filter): ﬁlters away lower frequencies while letting higher frequencies through.
LPF (Low-Pass Filter): ﬁlters away higher frequencies while letting lower frequencies through.
Microphone Feedback Suppression: used to prevent feedback howling when recording high volume.
PEQ (Parametric EQ): used to adjust the coloration of the audio signal. Set the center frequency of a band, and freely adjust the EQ parameters of the band. Q can be used to adjust the bandwidth. n d
HSEQ/LSEQ (2 Order High/Low-Pass Slope Filter): used to boost or attenuate the highs or lows of nd audio signals, which can eﬀectively control the coloration of a wide range of frequencies. 2 order ﬁlters have a 12dB/octave slope, and have +12/-24dB boost/attenuation range.
Q (the ratio of center frequency to bandwidth): used to adjust PEQ bandwidth. The lower the Q value, the wider the bandwidth (wider frequency coverage), and vice versa (narrower for a more accurate equalization). This parameter only applies to aforementioned PEQ bands.
Gain: used to boost or attenuate output audio signal. For example, -6dB refers to a 6-decibel attenuation of the output audio signal, while +12dB means a 12-decibel increase of the output audio signal.
EQ PASS: when selected, the EQ will be turned oﬀ, and the frequency band of the current channel becomes ﬂat.
Compressor: compression over a dynamic range. When the output signal reaches the “Compression Attack Time”, the compressor will engage to control the signal level. Mostly used to prevent speaker damage from excessively high level of peak audio signal.
Delay: can be used to help synchronize signals of diﬀerent speakers, making the output speaker signals reach the audience at about the same time, decreasing phase distortion.
Echo: consist of multiple delay-generated artiﬁcial echoes. By mixing processed and unprocessed signals, the singer’s voice can sound more compelling. A desired karaoke eﬀect can be achieved by ﬂexibly adjusting the echo time, feedback and level.
Reverb: similar to the echo eﬀect. It enhances the vocalist’s voice and makes it sound more live.
Initial Volume: the conﬁgured default volume for the device after each bootup.
Max Volume: the conﬁgured maximum volume adjustable for the device.
