When using an external input signal, could I damage the Qohm2 source or the Qam/Qca am- plifier? The Qam/Qca amplifier input will withstand any type of normal signal coming from any measurement device or computer on the headphone outlet.
  • Page 8 So, in such a case only one channel should be connected to the input speakon socket of the Qohm2, and only the output power on this one channel will contribute. Leaving the other channels unused (open) will not harm a normal amplifier.
