fig.basic The monitor output jacks provide both phone type and RCA phono type connectors. The same signal is output from both types of connector. Use the connectors that are suitable for the cables you are using with your monitor speakers. If plugs are inserted into both the phone jacks and RCA phono jacks, sound will be output only from the phone jacks. * Before you connect monitor speakers or headphones, turn the monitor volume knob or headphone volume knob, as well as the volume of your monitor speakers, all the way to the minimum position. Adjusting the volume fig.mic4 1. If you have connected monitor speakers, raise their volume to an appropriate level. 2. Turn the monitor volume knob or headphone volume knob toward the right to adjust the volume as desired.

The XLR jacks can provide phantom power for condenser mics that require it. The phone jacks can accept either balanced or unbalanced connections. If you are using a condenser mic that uses phantom power, turn on the phantom power switch. * You must leave the phantom power turned off unless you are using a condenser mic that requires phantom power. Malfunctions will occur if phantom power is supplied to a dynamic mic or an audio playback device. For details on the specifications of your mic, refer to the owner’s manual supplied with your mic. (The M-100FX’s phantom power supply is DC 48 V, 10 mA maximum.) Before you connect a mic, turn the input level knob (GAIN) to the minimum position in order to protect Mic the circuitry. Video deck Video camera Video signal Stereo headphones Phantom power This is a method of supplying power for a condenser mic or similar device via the mic cable. The built-in phantom power supply provides 48 V (direct current). The shape of the plug is identical to that of a conventional XLR plug. Basic operation English 21 Types of mic Mics can be broadly classified as either dynamic mics or condenser mics. The M-100FX can accept either type, and can also accept “plug-in powered mics”—the miniature condenser mics designed for connection to the mic jack of a computer or the recording jack of an MD (mini disc) recorder. The plug-in powered mic jack accepts either monaural or stereo mics. If a stereo plug is connected to mic input jack 1 (INPUT 1), channel 1 will process the left/right signals in stereo. If a plug-in powered mic is connected, and you connect a mic to the XLR jack, no audio will be input from the mic connected to the XLR jack. Only the signal from the plug-in powered mic will be sent to the mixer. If you are using the plug-in powered mic jack, the input level knob (GAIN) will not adjust the input level. About balanced and unbalanced connections Balanced input is a method of transmitting a signal using three conductors, which are named “hot”, “cold”, and “ground”. The plug is divided into three sections. Plugs used for stereo signals are divided into three sections in the same way, but are wired differently. Do not mix these two type of connections. Stereo signals cannot be input to mic input jack 1 or jack 2 (INPUT 1, 2). Unbalanced input is the usual method of transmitting a signal using two conductors, a signal line and a ground. The plug is divided into two sections. XLR plug TRS phone plug (balanced) Phone plug (unbalanced) 1:GND 2:HOT 3:COLD GND(SLEEVE) HOT(TIP) COLD(RING) Only a plug-in powered mic can be connected to the plug-in powered mic jack. If a different type of mic, such a mic with a conventional stereo mini output plug is connected to this jack, the circuit may be damaged. 22 Basic operation Adjusting the gain and level (volume) After you have made connections, use the following procedure to adjust the volume appropriately. 1. Lower the input level knob (GAIN), master volume fader, monitor volume knob, and headphone volume knob to their minimum positions. 2. Adjust the gain. While speaking/singing/performing into the mic, turn the input level knob toward the right for the channel to which your mic is connected. Adjust the input volume so it is as high as you can get it without causing the peak indicator to light. fig.mic1 3. Set the master volume fader to the center of the area shown in the panel illustration below. fig.mic2 4. Adjust the input level. Adjust the input level fader so that the yellow LED (0 dB) of the master volume indicator lights occasionally. If you are simultaneously recording with more than one mic, slowly raise the input level...
