Introduction
Bass Roll off models
only
Before making your
first important recording, it is suggested that you experiment with your new
microphones and battery unit a bit. There are 7 different bass roll-off frequencies
to choose from: 16Hz, 69Hz, 95Hz, 107Hz, 160Hz, 195Hz and 888Hz. You will
find that different recording situations require a different bass roll-off
frequency to produce the best results, depending on many factors such as the
type of microphone you are using, the venue itself, shape of the room, your
position in the room, speaker placement (if any), and many other factors.
You should experiment with the different roll-off frequencies to see which
one(s) produce the sound that you like the best. To set the roll-off frequency,
set the switches according to the following chart:

Using
the module with a Sound Professionals
microphone
If
you are using the battery module with one of our microphones, simply plug
the microphone’s connector into the battery module’s input jack. The microphone
is now receiving power from the battery module, and you are ready to proceed.
This module is NOT to be used with the SP-MICRO series microphones.
If you are using the battery module with
a microphone other than a Sound Professionals microphone, the procedure for its
use is the same as noted above. Be sure the microphone is designed to use
at least 9-12 volts DC bias power (or plug in power) and has a 1/8” stereo
phone plug.
Now you may plug
the 1/8” stereo output cable into your recorder using one of the following
procedures:
1.
If you are going to record very quiet
sounds, (nature sounds, human speech, chamber music, meetings, etc.), it is
suggested that you use the microphone “in” jack of your recorder using the
-20dB setting (if you have one). This should produce excellent results with
these types of sources. You may find it necessary to change to the different
-dB setting if you have to turn the recording level controls up near their
maximum settings at the -20dB setting. Important note: If you DO NOT have
a mic sensitivity switch or setting on your recorder (some SONY MD recorders),
you may need an optional attenuator cable for sounds that are too loud for
the mic input and not loud enough for the line input. This cable is available
at your local Radio Shack or on our web site part # SP-ATEN-1. If you have
the level control option, you don’t need the cable-the level controls perform
the same function more effectively.
2.
If you are going to be recording loud
sounds (rock concerts, full orchestras, close miked instruments, etc.), it
is suggested that you use the “line in” jack of your recorder. This will produce
excellent results with these types of sources. Rule of thumb is to always try the line input
first. If you can get levels strong enough to use the line input-use it, as
you will generally get cleaner recordings using the line input.
You may now begin
recording, following the directions provided by your recorder’s manufacturer.
After a few minutes of recording, stop the recorder and listen to the recording
you have just made. Adjust the microphone placement, recording levels and
the bass roll-off frequency as needed. Repeat this procedure until you are
satisfied with the results. You are now ready to make that once-in-a-lifetime
recording!
Remember to unplug the microphone from the
battery box when not in use to conserve battery power. As long as the microphone
is plugged in, the module is “ON”.
If you have the
level control option, you will be able to adjust the output of your microphones
at any time, even while recording. This will have the same effect as adjusting
the recording level on your recorder or lowering the mic sensitivity.
When you are ready
to begin recording, follow the directions provided by your recorder’s manufacturer
to set your recorder into the “record” mode. Set the recording levels on
your recorder at or near maximum gain. While viewing the record level meter on your
recorder, adjust the level controls on the battery module to achieve the desired
recording level. The level controls
may be adjusted at any time while recording. After a few minutes of recording,
stop the recorder and listen to the recording you have just made. Adjust the
microphone placement, recording level and the bass roll-off frequency as needed.
Repeat this procedure until you are satisfied with the results. You are now
ready to make that once-in-a-lifetime recording!
