TONE for WIRED and WIRELESS MICROPHONE and MUSIC

TONE adjustment is actually used to increase or reduce the high/low frequency component of the speaker’s restored sound. It is so-called raising or attenuating HIGH (HI) / BASS (LOW) via frequency-specific volume knob to improve human voices or make musical instruments’ sound more prominent. According to the scale mark on the panel, clockwise adjustment is to increase / boost high frequency and decrease / attenuate low frequency, opposite to increase / boost low frequency and decrease / attenuate high frequency.
Adjust the level of high frequency (HI) and low frequency (LOW). All signals have been balanced by the high and low sounds after entering the amplifier so it is not necessary to adjust the TONE during the output to the speaker. It is recommended to maintain the position of TONE at just 12 o’clock. Adjustment reference:

• HI (TREBLE): It is the basic part of the sound. It accounts for 70% of the entire audio energy and is an important component to display the music style. When appropriate, the BASS is relaxed and the sound is full and soft. If you feel the sound is thin, you can moderately increase the BASS. If you feel the sound is muffled, not clear, or too nasal, you can moderately reduce the BASS.
• LOW (BASS) : It’s the frequency that affects the sound layering. If you feel that the sounds of instruments such as Piccolo and Flute are too prominent, or the tooth sound of the voice is too heavy and the tone is sharp, you can moderately reduce the TREBLE.

VOICE PRIORITY

Voice Priority operation is only necessary when CD/USB/MP3 is playing.
When the Voice Priority switch is ON, the ducking function will be activated. While the music is playing, a voice input from either a WIRED or WIRELESS MICROPHONE will temporarily override and lower the volume of the background music and voice could be heard more clearly. Background music will return to its original setting when no audio input is entering the microphone after certain seconds. However, if the microphone is not switch off, the reentering of music into the microphone will also activate the voice priority function.

Application

Connecting L/R stereo speakers (SP OUT)

Plug the external speaker’s audio cable to the 4P PHOENIX jacks on the rear panel. The speaker’s impedance must be 4-8Ω or more. When using 4P PHOENIX for connection, please accord with the positive (+) and negative (-) polarities.
