Denon DN-720R Proper Recording Level, Recording Bias Adjustment, Recording Adjusting

POWER

Push the switch to turn "ON" the power.

EJECT

Press the EJECT button to open the cassette compartment.

Cassette Compartment Cover

(Make sure the erasure prevention tab has not been removed from the cassette shell half.)

DOLBY NR

Set, in accordance with the recording to be made. For recordings without Dolby NR, set to "OFF". For recordings with Dolby B NR, set to "B" (The B-NR indicator will light up). For recordings with Dolby C NR, set to "C" (The C-NR indicator will light up). future mistakes during playback can be avoided if the cassette is so marked for Dolby NR encoded recordings.

MPX FILTER

Button it "ON" for the DOLBY NR recording of FM broadcasts (The MPX FILTER indicator will light up).

•REC/REC MUTE When pressed, the deck goes into the record standby mode. The O REC and ll PAUSE indicators will light. Initial setting of recording levels should be made in the record standby mode. The tape speed control is set to the fixed mode and "FIX" lights on the display.

INPUT LEVEL

Used to set the recording level.

►PLAY

When pressed, the recording will start.

(The PLAY and O REC indicators will light up).

Note:

In the recording mode, the variable speed mode cannot be selected, and the mode is automatically switched to the fixed speed mode.

When recording is finished, press the STOP button.

Caution:

Be careful not to erase important recordings by mistake. Mis-erasing can be avoided by following the two steps below:

1.If the PLAY button is pressed while the REC indicator is on, the tape will be recorded.

2.If the PLAY and RECORD button are pressed at the same time, the tape will be recorded.

3.Performing the record pause or the stop operation during recording will create a discontinuous portion in the recording signal. The previously recorded signal may remain after erasure at this connecting portion. Also, a very small amount of the end portion of the previous song may be erased.

PROPER RECORDING LEVEL

A too high recording level can saturate the tape and cause distortion. On the other hand, if the recording levels are set too low, soft passages will be marked by residual noise. Proper recording level is the single most important factor for making well balanced recordings.

Guideline for maximum recording level

Normal tape TYPE 1

Cr02 tape

TYPE II

Metal tape

TYPE IV

+1 dB levels on peaks

+3 dB levels on peaks

+5 dB levels on peaks

Note: Optimum recording levels can differ depending on program sources or the type of tape used.

RECORDING BIAS ADJUSTMENT

For best recording results, monitoring during the recording process and comparing various recordings using your own judgment are essential. The cassette. deck is equipped with independent bias adjustment controls for the left and right channels to assist you in setting the proper bias for different types and brands of recording tapes. At the center-click-stop position, the deck is set for a reference bias level for NORMAL, Cr02 and METAL tapes. If the resulting recording in this position has too much or too little high frequency content, varying the bias adjustment control can be useful to achieve better results.

If the high frequencies (treble sounds) are to be boosted, turn the bias control counterclockwise to decreases bias current. If distortion is of more concern than high frequency response, turn the control clockwise to increase bias current. By the use of this control, you can record tapes with response that matches your personal listening tastes.

RECORDING ADJUSTING

The recording and bias levels can be fine-adjusted for the tape being used. For details, refer to the enclosed adjustment sheet.
