taste or need. Finally, you may find that more natural sounds result when you use wider band-
widths for boosting, narrower bandwidths for cutting. Regardless, there are no hard and fast rules
and in the end, whatever works for you is best.
It’s generally easier to apply boost to a sound for shaping (and that’s how many engineers start).
Many times, however, you may want to experiment with removing an offending sound (as opposed
to drowning it out with something else). In a complex mix, this may work better because it may
require less overall EQ to remove the offending sound; the end result will sound more natural.
Phantom Power
In a nutshell, here are the do’s and don’ts of phantom powering:
DO: Verify that your microphone can be phantom powered (if it is a condenser mic).
Ensure that your microphone’s output is low impedance, balanced and floating. This is
especially important for ribbon mics.
Turn the phantom power off when connecting vintage ribbon microphones.
Mute your monitor speakers or headphones when turning the phantom power on or off.
If you don’t, there will be a loud, nasty pop.
Mute your monitor speakers or headphones whenever you plug in or unplug a phantom
powered microphone. If you don’t, there will be a loud, nasty pop.
DON’T: Plug in an A-B powered microphone without a suitable adapter.
Worry about your dynamic or ribbon microphones, as long as they are wired so that the
output is balanced and floating.
Use the microphone input for line-level sources, especially those that are transformerless.
Use the microphone input with unbalanced sources. Use a direct box to convert the
unbalanced source to balanced. Then, connect the balanced direct box output to the
527E’s microphone input.
Worry about your tube condenser mics. They are compatible (although they cannot be
phantom powered).

will mute the output by at least 60dB. Any SPST switch or relay contact will work.
Note Do not apply any external power source to the mute connector. Do not use the ground
terminal for any purpose other than mute switching.
The open-circuit voltage at the positive terminal is 5 V (DC limited by approximately 20k Ohms).
