Adjusting the Recording Level
Having the proper recording level is essential to making
good, intelligible recordings. If the level is too low, the
recording will contain a lot of hiss when it is played back
loud enough to hear. If the level is set too high, loud
sounds or speech will “clip” and the sound will be
distorted. Clipping occurs when the level of the signal
being digitized exceeds the maximum level of the analog
to digital converter. In cases of severe overload, the
recording of the second channel in a stereo pair may be
affected. Channels 1 and 2, and channels 3 and 4 are
paired.
The VU meters in the Antex Mixer Program are used to
adjust the recording level. Note that the meters are
only active when a recording program is
monitoring or recording. As a rule of thumb, speak
at a normal level into the microphone. Adjust the Input
Slider on the Antex Mixer Program until the VU meter
peaks are in the –15 to –20dB range. This should give
adequate “headroom” for loud sounds.
Recording Mix Matrix
The recording mix matrix can be used to route any
combination of inputs to any of the 4 record channels.
This is done by clicking on the record channel number
buttons associated with each input, using the Antex
Mixer Program. Each input has 4 buttons for record
channels 1 through 4. Click on the button with the
mouse to toggle it on or off; blue means on, gray means
off.
