JVC TD-W354 manual Microphone Mixing During Recording, Recording Level Adjustment, Erasing

MICROPHONE MIXING DURING RECORDING

By connecting a microphone, microphone mixing during record- ing is possible by following the recording procedure. Adjust the microphone input level by setting the record-pause mode and observing the peak level indicators.

·When the record-pause mode is set and the INPUT LEVEL control is set to MIN, sounds are output only from the micro- phone, and it can be used as a public address system.

RECORDING LEVEL ADJUSTMENT

Adjust the recording level while observing the peak level indica- tor indication.

For example:

With metal tape

Because of metal tape's higher saturation level, it is OK that ``+ 2'' lights occasionally.

With normal or chrome tape

It is OK that ``+ 0'' lights occasionally.

·When the recording level is too low, the hiss noise inherent in the tape will be conspicuous.

·When the recording level is too high, exceeding the saturation level, the recording will contain cracking noise and will be dis- torted.

·If ``+ 4'' lights too often because the recording level is too high, the recorded sound may be distorted and seem to be breaking up. If only ``0'' lights infrequently, the level is too low and the recording may contain tape hiss.

It is best to adjust so that the maximum sound level of the source to be recorded reaches the very limit of the saturation level of the tape to be used.

The best level varies depending on the type of music and type of tape so it is better to make a test recording, using FM music, records, etc.

AUTOMATIC RECORD MUTING (DECK B)

This facility is used to eliminate undesired sections and leave an appropriate non-recorded section.

A. To leave non-recorded sections of about 4±5 seconds automatically

1.When the undesired section comes during recording, press the REC/REC MUTE button and release it.

2.The REC indicator flashes and a non-recorded section is made during record muting operation. About 4±5 sec- onds later, the tape automatically stops, and the unit enters the record-pause mode.

3.Press the PLAY button to start recording again.

B.To leave non-recorded sections of more than 4±5 sec- onds

1.Keep the REC/REC MUTE button pressed continu- ously as long as you want to make a non-recorded sec- tion. By releasing the finger from the button after the above operation, the unit enters the record-pause mode.

2.Press the PLAY button to start recording again.

C.To leave non-recorded section of less than 4-seconds When the undesired section comes during recording....

After the REC/REC MUTE button is pressed, press the PLAY button before the unit enters the pause mode to start

recording again, or press the PAUSE button to enter the record-pause mode.

·The peak level indicator lights even during record muting according to the input level which can be heard from the speakers or headphones so that recording can be resumed at the exact point on the tape.

ERASING

When recording on a prerecorded tape, the previous recording is automatically erased and only the new program is recorded on the tape.

To erase a tape without making a new recording...

Follow the section ``RECORDING'' but in step 8, set the INPUT LEVEL control to MIN.

DOLBY NR and DOLBY HX PRO

Dolby NR System

To reduce the hiss inherent in tape recording, use the Dolby NR System when making recordings. When listening to a tape recorded with the Dolby NR System, press the DOLBY NR but- ton to set to B or C according to the system selected in the recording mode.

Note:

The sound quality will change if the setting of the DOLBY NR button is different in recording and playback.

Dolby HX PRO headroom extension

When a source which contains many high-frequency compo- nents is recorded, these high-frequency signals have the same function as bias and therefore, the effective bias current changes.

This will result in phenomena such as changes in the level of low-frequency signal and subsequent distortion and reduction of the high-frequency saturation level.

Dolby HX PRO headroom extension system controls the bias current so that the effective bias is constant even when there are fluctuations in the high-frequency components of the input signal.

This greatly improves the high-frequency saturation level while reducing the low-frequency signal level variations and distortion.

·The dynamic sound recorded with this system sounds the same even when the tape is played back in a deck that does not have Dolby HX PRO.

·This system automatically works when in recording; however, Dolby HX PRO is not a noise reduction system.
