* Depending on your system, this may be affected by noise from your computer.
• Connect the UA-700's grounding terminal (p. 128) to the grounding terminal of your record player.
• Connect your computer and the UA-700 to separate electrical outlets.
• Correctly ground your computer. (Refer to the owner's manual for your computer.)
4. Center cancel switch
This switch erases the signals localized at the center of the stereo signal that is input. This function
is useful when you are creating karaoke data.
* In some cases, such as when effects have been applied to the signal, it may not be possible to erase the center signal.
* Since this processing avoids canceling the bass drum and bass guitar, it may not be possible to erase the vocal from the song if
it contains a large amount of low-frequency components.

Noise suppressor
This effect suppresses the hum and noise that are picked up by a guitar pickup or microphone.
Since the noise is reduced according to the envelope (volume change) of the input sound, a natural
effect is obtained with virtually no change to the input sound.
2. Noise suppressor sensitivity knob
Adjusts the threshold level according to the level of the noise. If the noise is loud, turn this knob
clockwise. Adjust the knob so that the decays of the input signal will sound natural.
* High settings of the threshold control may cause the beginning or end of notes to sound unnatural, and you
may hear no sound at all if the volume control of your guitar is turned down.
1. Line input jacks
Use these jacks to input audio signals from an audio device or
MIDI sound module.

you to directly connect a record player. If you are using a record
player with a built-in equalizer, leave this switch turned off.
