FUNCTIONS AND CONTROLS

CHANNEL INPUT

1. [MIC] Input Jack – – This is a balanced XLR microphone input jack This XL input jack is to be connected to a microphone through a balanced microphone cable with a male XLR plug.
2. [LINE] Input Jack – – This is an unbalanced 1/4″ input jack. This 1/4″ input jack is to be connected to a microphone, a musical instrument, or an audio device (such as CD player) through an unbalanced cable with a 1/4″ TS plug.
3. *[INSERT] Jack --** This is a 1/4″ TRS phone jack allowing you to insert external line devices (such as gating, compressing, equalizing, and /or reverb effects) into the signal path. This insert jack is configured with “TIP” send and “RING” return.
4. [GAIN] Control Knob – – This knob is used to raise or lower the gain level of the input signal. When the audio level is higher than a predetermined threshold, the [PEAK] LED indicator (refer to numeral 9) will keep blinking until the audio level goes below the threshold.
5. [HIGH] Treble-tone Control Knob – This knob is used to adjust the gain for the input signal band centered at 12.5KHz in the range from -15B to +15dB.
6. [MID] Alto-tone Control Knob – This knob is used to adjust the gain for the input signal band centered at 2.5KHz in the range from -15dB to +15dB.
7. [LOW] Bass-tone Control Knob – This knob is used to adjust the gain for the input signal band centered at 80Hz in the range from – 15dB to +15dB.
8. [FX] Control Knob – – This knob is used to adjust the level of the signal routed from this channel to the reverberation line. This signal level will vary according to the settings of the channel attenuators (HIGH, MID, LOW). The signals from the stereo channel (Rand L) will be mixed before being routed to the reverberation line
9. [PEAK] LED Indicator — This PEAK LED indicator will keep blinking when the input signal level is higher than a predetermined threshold. When the PEAK LED indicator is blinking, adjust the gain control knob (refer to numeral 4) to a lower gain level until the PEAK LED indicator stops blinking to maintain the sound quality.
10. [LEVEL] Control Knob – This knob is used to raise or lower the audio volume of the signal from this channel.

STEREO AND AUX CHANNELS

1. USB interface and MP3 display — The volume and sound quality of the audio signal from the USB interface are controlled by the control knobs of the [7/8 USB] channel.
2. [+48V PHANTOM] Button/LED — When one or more condenser microphones are connected to the XLR [MIC] input jacks (refer to numeral 1 in the CHANNEL INPUT section), press this [+48V PHANTOM] button to turn on the 48V phantom power to the condenser microphones via the XLR [MIC] input jacks. When the 48V phantom power is turned on, the phantom power LED light will be turned on.

When the red LED light is turned on frequently, the [MAIN OUT] output signal level may need to be lowered by adjusting the [STEREO] level fader (refer to numeral 6). The red POWER LED indicator lights are placed below the green level meter LED lights.
2. [DELAY] Control Knob — This control knob is used to adjust the depth of the reverberation.
3. [REPEAT] Control Knob — This control knob is used to adjust the repetition times of the reverberation.
4. [FX LEVEL] Control Knob — This effects return level control knob is used to adjust the volume of the reverberation effect.
5. [PHONES Level Control Knob — This control knob is used to adjust the earphone volume.
6. [STEREO] Level Fader — This level fader is used to adjust the [MAIN OUT] output (refer to numeral 1 in Section MAIN TERMINALS) signal volume.
