DSP I/O Expansion Cards

Are all inputs on the 4 Channel Analog Input Card mic or line switchable?
Yes, all analog inputs are mic or line switchable.
Will phantom power damage my non-condenser microphones?
Generally no, some older ribbon microphones are somewhat susceptible, but itís always a safe bet to disable phantom power when not needed.
Does the 4 Channel Analog Input Card have the same mic pre as the Radius 12◊8 and Radius AEC?
Yes, the same input circuit is used for all Composer hardware.
Does the Analog Input Card have full 48 v phantom power on all inputs?
Yes, all card inputs (analog or AEC) have full 48 v phantom power.
What is Phantom Power?
Phantom power derives its name from its invisibility to audio signals, even though the microphone cable carries both phantom power (as direct current) and audio signals (as alternating current). Specifically, the term phantom power means a positive DC voltage sent to the microphone on both audio leads, through current-limiting resistors which also serve to isolate the audio leads from one another. The front panel phantom power button applies phantom power via pins 2 and 3 of the mic input XLR connectors.
Do the inputs of the 4 Channel Analog Input Card need to be padded to receive the output of a mixer or console?
No
What is the max output of the 4 Channel Analog Output Card?
The max output is 24dBu.
Is it OK to hot swap a 4 Channel Analog Output Card with a different I/O card?
No, it is never OK to hot swap a I/O card in a Symetrix DSP. Please take the Composer certification for more info on this procedure.
Does the 4 Channel Analog Output Card have any level controls?
Yes, the 4 Channel Analog Output Card has a gain fader with a range from Off to +12dB.
What if I order an Edge or Radius Frame but do not fill up the card slots?
Filler panels will reside in the empty slots.
