48v Status Indicator [F10]
The 48v Status LED [F10] is a Bicolour LED that displays the full 48v status of the preamp. Due
to the design of Camden EC2’s preamps and its internal circuitry, the 48v can take a while to
charge and discharge during use. As a safety feature and to prevent damage to your
microphones, Camden EC2 displays the voltage status of the 48v using a 3rd, ‘Amber’, colour.
Off
48v Off, voltage fully discharged
Amber
48v voltage charging/discharging
Red
48v fully charged
Engaging 48v
When first engaged, the 48v Status Indicator LED lights Amber whilst the voltage is
reaching the full 48v. During this time, do not adjust the Gain control as doing so may
cause pops and clicks through the preamp output as the caps are still charging.
When the 48v Status Indicator lights RED, the 48v is fully charged and the preamp is
ready for use.
Disengaging 48v
When disengaged, the 48v Status Indicator LED lights Amber whilst current is
discharged from the XLR connector. During this time, do not disconnect the
microphone/DI Box or connect a ribbon mics to the XLR as voltage is still present.
Once the LED has turned off, there is no longer any voltage present on the XLR
connector and the preamp is ready to use.
Note:
Some microphones may take longer to charge/discharge than others and so
the duration of the Amber LED status may change depending on what
device is being used.
Warning:
Do not connect/disconnect microphones from Camden EC2 when 48v
Phantom Power is engaged as doing so could cause damage to Camden EC2
or your connected microphone. Damage caused during improper 48v usage
is not covered under warranty.
