48v Switch:
The 48v switch engages 48v phantom power and sends supply voltage down pin 1 of the chassis’ XLR
input socket to power condenser microphones and Di boxes if required.
Note:
Do not engage 48v with vintage ribbon mics connected to Camden 500 as sending voltages through to
the ribbon can cause permanent damage to the microphone.
Be careful when connecting line-level instruments to Camden 500 via XLR when 48v is engaged. Sending
48v through to the line-level outputs of instruments and playback devices can cause irreparable damage to
their internal components.
Polarity (Ø) Switch:
The polarity switch flips the polarity of the incoming audio by 180° in order to optimise the phase
interaction of the preamp’s signal with other audio tracks also being recorded.
Note:
In isolation, flipping the polarity of the mic preamp will not result in any audible effects, however the
polarity switch is a useful tool when Camden 500 is being used as part of a multi-mic recording setup, or
instances where other instruments - also being mic’d and recorded - are bleeding into the microphone.
HPF Switch:
The HPF (often called Low Cut) switch engages a filter that removes low-end rumble from sources that do
not require low frequency extension. The filter is set to achieve 3dB of attenuation at 80Hz and features a
12dB per octave slope.
Camden 500’s High Pass Filter has been tuned to achieve a smoother onset but more dramatic roll-off than
standard filters resulting in a more natural-sounding low-frequency attenuation.
Note:
As the HPF is positioned after the Mojo circuit in the signal path it can also be used in conjunction with
Mojo to create more even more tonal-shaping possibilities.
-
Try using Thump on a vocal track alongside the HPF to introduce a rich and intimate low-mid
harmonics without excessive plosive or rumble effects in the lower frequencies.
-
Try using Cream on an electric guitar mic alongside the HPF to achieve more high-mid harmonic
focus, dynamically remove mid-range boxiness, and guitar cut through a mix whilst using the HPF
to trim the low-end ‘woof’ coming from the cabinet itself.
