Mono MIC/LINE Channels, Phantom Power +48 Volt

4.1 MONO MIC/LINE CHANNELS

These are channel 1 through channel 8. You can connect balanced, low impedance microphones or a low level signal to the XLR socket. On the 1/4" line jack you can connect either a microphone or a line level instrument such as synthesizers, drum machines, effect pro- cessors or any other line level signal.

Note: You shall never connect an unbalanced microphone to the XLR socket if you do not want to damage both the microphone and mixer. Also, it is not possible to simultaneously use both the MIC &LINE inputs on the same channel, use only one of them for the appropriate source.

PHANTOM POWER +48 VOLT

It is available only to the XLR MIC sockets. Never connect a mic- rophone when phantom power is already on.

4.2 MONO CHANNEL INSERT

Insert sockets are provided for all mono MIC channels. It can allow you patch external signal processing devices into signal path via a TRS connector, the signal will be taken out after the input gain control (TRIM), and sent to an external processor such as a compressor- limiter, then returned into the same channel imme- diately before the EQ section.

Note: Usually, insert connections require a special stereo-splitting Y-cord to be connected, known as TRS connector (Tip Send/Ring Return).

4.3 INPUT LEVEL SETTING

This control is provided with 2 different indication rings: one is for the microphone and the other for the line level. When you use a microphone you shall read the OUTSIDE ring (0 ~ 44dB), when you use a line level instrument you shall read the INSIDE ring (+15 ~ -30dB). For optimum operation you shall set this control in a way that the peak LED will blink also occasionally in order to avoid distortion on the input channel.

By pressing this button you will activate a 75Hz low frequency filter with a slope of 18 dB per octave. You can use this facility to reduce the hum noise caused by the mains power supply, or the stage rumble while using a microphone.

4.5 STEREO INPUTS

These are channel 9 through channel 16. They are organized in stereo pair and provided with 1/4" TRS sockets. Use the left input if connect a mono input signal to the STEREO INPUT.

4.6 +4dBu/-10dBV

These switches select the input sensitivity of the line inputs on the stereo channels CH9 ~ CH16. +4dBu is suitable for professional audio devices, -10dBV is suitable for general HI-FI devices. If not sure to use which setting, try +4dBu first, or change it to -10dBV if the volume is too small to be satisfied.
