Adjusting the input source volume (Input Sensitivity)
The output from guitars, bass guitars, microphones, keyboards, and other instruments all enter the BR-1600CD as
continuous electrical waves. This type of output is referred to as an analog signal. Inside the BR-1600CD, circuits
known as A/D converters are used to convert these analog signals into digital signals. If the volume of an analog
signal is too high, unpleasant distortion will occur in the corresponding digital signal; however, if the volume of this
signal is too low, the noise that is generated during conversion to digital will become very noticeable. Once
distortion or noise becomes obvious in a digital signal, it is extremely difficult to restore the quality of the sound
using any amount of post-processing. In order to record with good sound quality, therefore, it is extremely
important that you adjust the volume of the analog signal in such a way that the source can be made as loud as
possible without distorting. Adjustment of a sourceOs volume while it is still an analog signal is carried out using the
INPUT SENS (Input Sensitivity) knob.
If it lights up occasionally when the
instrument is played hard:
1Play the instrument to be recorded.
The volume is at a suitable level and does not need to
If it never lights up:
2Check whether the PEAK indicator for The volume is too low. Turn the INPUT SENS knob
that instrumentOs input source lights up
for the corresponding input source clockwise to raise
when the instrument is played hard.the volume to a level where the PEAK indicator lights
up only occasionally when the instrument is played
If it lights up frequently:
The volume is too loud. Turn the INPUT SENS knob hard.
for the corresponding input source counterclockwise
to reduce the volume to a level where the PEAK
indicator lights up only occasionally when the
instrument is played hard.
Y If a suitable volume cannot be obtained even when the INPUT SENS knob is used, it is quite possible that the output
volume of the instrument itself is improper level. In such a case, make sure that the instrumentOs volume is at a
suitable level, and then repeat the adjustment procedure described above.
Y If you are using a condenser microphone that requires phantom power, no sound will be output from the microphone
until the phantom power is turned on. Refer to the userOs manual that came with your microphone, and then turn on
the phantom power if the manual indicates that it is necessary. For more detailed information regarding usage of
phantom power, refer to OUsing condenser microphones (Phantom Power)Ã“ (OwnerOs Manual; p. 264).
Each PEAK indicator lights up when the corresponding analog signal reaches -6 dB, and distortion occurs in the A/D
converter when this signal rises beyond 0 dB.
