Default ARTA help

I would like to start testing my speaker design. I have the ECM8000, Tasco Links USB Phantom Power box, SoundBlaster X-Fi sound card, Atma-Sphere all balanced pre and power amps. The power amp will take an RCA input.

The sound card only has 1 (mic) input, and 3 outputs. All mini plugs.

Am I safe in assuming I use the monitor out of the Tasco to the mic in of the sound card?, or should I use the headphones out on the Tasco?.

If I am reading the ARTA manual correctly, I need a cable to go from the soundcard out and into the power amplifier. Am I safe in assuming I need to make a cable which is mini plug at one end, and RCA out at the other?.

Is the ARTA measuring box a good investment, and where would I get one?.

The voltmeter's I can find all have two prongs. Is there a concesus on the best type of electronic voltmeter to use?. Will I need to redo the measuring ends?.

Thanking you all in advance. Bill

Impedance varies with frequency, use impedance plots of your drivers and make crossover calculations using the actual impedance of the driver at the crossover frequency
