17.Gain control knob [LINE-MIC] Adjust the gain for best S/N ratio. The output signal level from the sound sources (mic, keyboard, guitar, etc.) should be set in such a way that the output of the source should be neither too high or low. The difference can be corrected with the gain control. < Gain control rule of thumb > The gain is adjusted by rotating the [LINE-MIC] knob while watching the lighting condition of the level meter LED as the signal is input. Gain of "MIC" is obtained at full CW rotation of the [LINE-MIC] knob and "LINE" at full CCW rotation. Ideal gain is obtained by setting the level meter reading such that the "+6" LED does not light up. Should the "+6" LED lights up frequently, it is an indication that gain is too high and will result in distortion if recording is continued in this manner. Basically, the knob should be adjusted toward "MIC" when a low level sound source such as a mic is connected, and toward "LINE" when connecting the output of an effects unit to which a keyboard or electric base is connected. LINE (-10dBV) MIC (-50dBV) The X-12 uses the following connection plugs: Stereo phone plug (stereo type) Use this plug to connect to the [PHONES] jack. Tip (L) Sleeve (ground) Ring (R) Tip (Hot) Sleeve (ground) Tip (Hot) Sleeve (ground) Phone plug (monaural type) Use this plug to connect to the [INPUT] jack. RCA pin jack (monaural type) Use this plug to connect to the [LINE OUT L, R] jacks on the rear panel. 8 Model X-12 Owner's Manual Basic Operation (recording) As explained above, there are four recordable tracks. The X-12, records each track independently. Let's try recording your mic/guitar/ keyboard on the track of your choice. As an example here, the mic sound will be recorded in track 1. 3 9 10 11 7 4 1 6 2 10 12 11 8 5 1 2 Connect the AC adaptor jack to the X-12's [DC IN] connector, and connect the power plug to the AC outlet. Do not handle the AC adaptor with wet hands or you may receive an electrical shock. Open the cassette lid and insert a recording tape into the cassette tray. If you record on a used tape, make sure that the write-protection tabs on the spine of the tape are not removed. If any of them are broken, cover the tab hole with a piece of tape. Plug the mic into the [INPUT] jack and the headphone into the [PHONES] jack. 4 5 Turn on the power switch. The [POWER] indicator will light up in red. Press the [PLAY] button to forward the tape for a few seconds. This should be performed in order to wind past the leader part at the beginning of the cassette tape. If a used tape is not rewound completely, press the [REW] button to rewind the tape to the beginning and perform Step 5. Leader partMagnetic tape 3 9 Model X-12 Owner's Manual 6 7 8 9 When the leader part is forwarded, press the [RESET] button to set the counter to "000." Select the track to be recorded with the [REC TRACK] selector. Select track 1 (the indicator will change to red) or whatever track you prefer to record on. This will change to red light and track 1 can be recorded. 1 Do not move the [REC TRACK] selector during recording. If this is moved accidentally during recording, the recording track will switch. Try speaking into the mic. The level meter LED will blink. For optimum gain, adjust the [LINE-MIC] knob CW (toward "MIC"). Adjust the [LINE-MIC] knob such that the level meter "+3" LED is illuminated at maximum sound volume. When recording line level sound sources such as a keyboard and electric guitar, the optimum gain is obtained by rotating the [LINE-MIC] knob CCW (toward "LINE"). 10 11 Put X-12 in the record standby mode. First, press the [PAUSE] button, then the [RECORD] button. The [PLAY] button will be engaged automatically at the same time. The tape will remain paused in the record mode. When the [LINE OUT/PHONES] knob is slowly advanced, the input monitor sound will be heard in the headphone. While monitoring the sound in the headphone, watch the level meter and adjust the recording to a suitable level. Because the recording level cannot be adjusted with a fader, optimum recording levels must be determined by the sound volume applied to the mic or by adjusting the distance to the mic. If you must monitor for a long time, be careful not to raise the[LINE OUT/PHONES] knob too high. If you monitor for long hours at high volumes, it could impair your hearing. 12 13 After confirming the level, release the [PAUSE] button (The [PAUSE] button is pressed again) to start recording. If recording is to be momentarily stopped, press the [PAUSE] button. If recording is to be ended, press the [STOP] button. Following the procedures up to this point, the sound applied to the microphone has been recorded on track 1 as shown in schematic below. Now, let's try recording another sound source to another track with the same procedures. Also, lets playback the recorded sound on each track as described below. Be careful not to continue recording, if the level meter "+6" LED lig...
