3.2 Connections
If your audio source has balanced XLR or ¼” TRS outputs, make
sure the wiring of those outputs corresponds with the wiring
of the R65/R80’s inputs as illustrated below. If it doesn’t, you’ll
need “crossover” cables that reverse the two signal conductors.
It is recommended that you use the shortest possible
cables in order to minimize the chance of picking up
electromagnetic or radio-frequency interference (EMI or RFI).
3.3 Input Level Setting
The Input Gain control determines the level of the
input signal before it is sent to the built-in power
amp. This lets you attenuate or amplify the signal’s
level at the monitor’s input, providing the flexibility
to adapt to various audio source output levels.
Set the Input Gain so that all other level controls in
the system needn’t be turned way up or way down to
achieve a comfortable listening volume. If you set it
too low, you’ll have to crank your audio source’s output
level way up, which will increase the audible noise from
the source signal. If you set it too high, any noise in the
signal will be amplified, which you don’t want, either!
The best place to start is to set the control at its 12 o’clock
position, which is labeled “U” for “unity gain.” That means the
level of the signal reaching the amplifier is the same as the
level of the signal entering the monitor’s input. This ensures a
good, strong signal level without amplifying any noise that
might be in the signal. Of course, you should make sure that
the gain controls in your audio source have been optimized for
maximum signal level and minimum noise. This process is
called “gain staging,” and you can learn about it from many
online sources.
