Frequently Asked Questions

I/O Expansion Cards – 4 Channel Digital Input or Output Cards

  • What if I order an Edge or Radius AEC Frame but do not fill up the card slots?

    Filler panels will reside in the empty slots.

  • The 4 Channel Digital Output Card supports AES and SPDIF, how does it handle the different impedance of the two formats?

    There is an impedance matching transformer on the 4 Channel Digital Output Card to switch between 110 Ohm and 75 Ohm.

  • SPDIF and AES are two channel formats, so does each of the two outputs on the 4 Channel Digital Output Card have more than one channel?

    Yes, each channel on the card sends two channels of audio. They are labeled 1 / 2 and 3 / 4.

  • Why is there no word clock input on the SymNet 4 Channel Digital Input Card?

    In both AES/EBU and SPDIF the word clock is embedded into the digital audio, so the digital input card will synch to the sample rate of the incoming signal.

  • Where can I find an Ethernet application with IP capable Symetrix products?

    SymNet Remote Terminal is a UDP terminal test application for testing Ethernet-based control for Symetrix products.

  • Why are there word clock inputs on the 4 Channel Digital Output card?

    SymNet digital outputs will be used to send digital audio to a 3rd party digital device which may be running on a different sample rate than Edge or Radius AEC’s internal rate of 48 kHz. With a word clock input respectively, each digital out pair can send audio at any sample rate between 32 kHz and 192 kHz.

  • Why does the 4 Channel Digital Output Card have a word clock input when this is an output card?

    It seems confusing at first glance, but the word clock output is there so that the 4 Channel Digital Output Card can output AES or spdif to a downstream device at any sample rate between 12 kHz and 96 kHz. When no word clock is connected the 4 Channel Digital Output Card will output at 48 kHz.

  • Why is there no word clock input on the 4 Channel Digital Input Card?

    Word clock is embedded into both AES/EBU spdif, so no word clock input is needed.

  • The 4 Channel Digital Input Card support AES and SPDIF. How does it handle the different impedance of the two formats?

    There is an impedance matching transformer on the 4 Channel Digital Input Card to switch between 110Ohm and 75Ohm.

  • Where can I find AutoCAD files for EDGE and the Symetrix audio I/O cards?

    Edge and audio I/O cards AutoCAD files 

  • Does the 4 Channel Digital Input Card have an impedance matching transformer?

    Yes, it matches 110 Ohm for AES and 75 Ohm for SPDIF respectively.

  • Does the 4 Channel Digital Input Card have sample rate conversion?

    Yes, it will accept any rate from 12 kHz to 96 khz and covert it to 48 khz.

I/O Expansion Cards – 4 Channel Analog Input or Output Cards

  • 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.

  • Is it OK to hot swap a 4 Channel Analog Output Card with a different SymNet I/O card?

    No, it is never OK to hot swap a I/O card in a SymNet DSP. Please take the Composer certification for more info on this procedure.

  • What is the max output of the 4 Channel Analog Output Card?

    The max output is 24dBu.

  • 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 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.

  • What if I order an Edge or Radius AEC Frame but do not fill up the card slots?

    Filler panels will reside in the empty slots.

  • Does the SymNet Analog Input Card have full 48 v phantom power on all inputs?

    Yes, all SymNet card inputs (analog or AEC) have full 48 v phantom power.

  • Where can I find AutoCAD files for EDGE and the Symetrix audio I/O cards?

    Edge and audio I/O cards AutoCAD files 

  • 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 SymNet Composer hardware.

  • Does the 4 Channel Analog Input Card have 48v phantom power on the inputs?

    Yes.

  • Will phantom power damage my non-condenser microphones?

    Generally no, some older ribbon microphones are somewhat susceptible, but it’s always a safe bet to disable phantom power when not needed.

  • Are all inputs on the 4 Channel Analog Input Card mic or line switchable?

    Yes, all analog inputs are mic or line switchable.
