1.CD Gain Selector
The CD Gain Selector will increase or decrease the input sensitivity of the CD input. We
suggest if your source unit's pre-amp voltage is 4V or greater, set the sensitivity switch to
HI. If your source unit's pre-amp voltage is 2V-4V, set the sensitivity switch to MID. If your
source unit's pre-amp voltage is less than 2V, set the sensitivity switch to LOW.
2.Subwoofer Frequency Selector
The Subwoofer Frequency Selector is a built-in low-pass filter for the Subwoofer Output.
Generally, the low-pass filter can be set to 128Hz, then the subwoofer amplifier's low-pass
filter is fine tuned for the desired response.
