Selecting the Appropriate Setting
for Your Connections
—Continued
• To accurately set the output levels, it is recommended
to use a handheld sound pressure level (SPL) meter.
Set the meter to C-weighting and slow averaging. A
Radio Shack
®
SPL meter or equivalent is
recommended. Using the internal channel noise
generators, set each channel so that you read a 75
decibel sound pressure level.

These input settings should be made so that the
DTR-7.4 is optimized for your connections. If the
default settings suit your connections, you do not need

the DTR-7.4, you can have “MD” appear when the Tape
source button is pressed.
