2.6 Parameter Description
1. Input Gain: used to compensate level difference between various input sources, especially those with
lower input level, for overall level consistency.
2. Volume Mixer: used to send signals from microphone or music or both to outputs.
3. HPF (High-Pass Filter): filters away lower frequencies while letting higher frequencies through.
4. LPF (Low-Pass Filter): filters away higher frequencies while letting lower frequencies through.
5. Microphone Feedback Suppression: used to prevent feedback howling when recording high volume.
6. 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.

7. 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.
8. 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.
9. 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.
10. EQ PASS: when selected, the EQ will be turned off, and the frequency band of the current channel
becomes flat.
11. 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.
12. 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.
13. 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.
14. Reverb: similar to the echo effect. It enhances the vocalist's voice and makes it sound more live.
15. Initial Volume: the configured default volume for the device after each bootup.
16. Max Volume: the configured maximum volume adjustable for the device.
