Controls
The RNT floor box features a switch for the attenuation pads, a switch for the low-cut filters, and a
switch for the polar pattern selection.
Gain Switch
The Gain Switch is located in the center of the floor box’s front panel. When
switched in, the incoming signal is either boosted (top position) or attenuated
(bottom position) by 12dB, using custom Rupert Neve Designs op-amps to
compensate for very loud or very quiet sound sources. Using the switch also helps
prevent overloading the input stage of recording interfaces, mixing desks and
microphone preamps.
HPF FREQ Switch
The HPF FREQ Switch is located on the left side of the floor box’s front panel , and
inserts a low-cut filter at 80Hz (top position) or 40Hz (bottom position). The
switch’s center position removes the filter for a flat frequency response . Wind noise,
plosives, footfall noise or rumble might affect the recorded signal, so enabling the
low-cut filters reduces such unwanted noise and prevents distortion. Additionally,
the low-cut filters also minimize the proximity effect when recording sound sources
at a very short distance.
Pattern Switch
The 9-position Pattern Switch is located on the right side of the floor box’s
front panel, and allows the RNT’s polar pattern to be changed from
omnidirectional to cardioid to figure-eight, with three additional steps between
each noted setting. This allows for great control over the balance between
direct and ambient sound.
Powering
The included floor box contains the outboard power supply for the RNT. No phantom power is
required from an interface or microphone preamplifier.
Before powering on, connect all required cables (IEC to power, XLR to preamplifier or interface, and
8-pin cable from floor box to microphone). Then turn the power on via the switch on the back of the
RNT floor box.
For best performa
nce, we recommend allowing approximately 15 minutes of “warm up” time before
recording. This allows the tube within the RNT to heat up and stabilize, and reduces the risk of
unwanted noise or distortion on your recordings.
Risk of damage
Do not connect the microphone to any power supply other than the
included RNT power supply. Do not apply phantom voltage (+48VDC) from
an external interface or preamplifier. This is the only way to ensure safe and
reliable operation.
