Be careful not to erase important recordings by mistake. Mis-erasing can be avoided by following:the two steps below:
1. If the PLAY (PLAY) button is pressed while the
RECORD indicator is on, the tape will be recorded.
PROPER RECORDING LEVEL
2. If the PLAY (PLAY) and RECORD (@REC) button are
pressed at the same time, the tape will be recorded.
A too high recording level can saturate the tape and cause distortion. On the other hand, if recording levels are set
too low, soft passages will be marked by residual noise.
making well balanced recordings.
Guideline for maximum recording level
Normal tape O dB levels on peaks
CrOz tape " 43 dB levels on peaks
Metal tape "45 ‘dB levels on peaks
@ Meter reading difference between L and R channels
Note:
Proper recording level is the single most important factor for
Optimum recording levels can differ depending
‘On program sources or ‘the type of tape used.
The left and right channels readings of the PEAK METER can differ due to variations:in input signal levels. In such
cases, adjust the individual channels of the BALANCE control! until identical meter readings are obtained for both channels.
RECORDING BIAS ADJUSTMENT
For best recording results, monitoring during the recording
process and comparing various recordings using your own
judgement are essential.
The DRM-400 is equipped with a bias adjustment
control! to assist you in setting the proper bias for different
types and brands of recording tape. At the center-stop
position, the deck is set. for a reference bias level for
NORMAL and CrO, tapes. If the resulting recording in this
position has too much or too little high frequency content,
- +
BIAS FINE
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 res-
ponse that matches your personnal listening tastes.
