Hi, Good Day! I bought a presonus Firepod 2 years ago and it's good and serve me good till now. Now, i'm actually looking for a Studio Monitor Switcher for audition/comparison when Mixing. Mean,i got 2 pair of studio monitor.And Firepod only provide an output (left and right) so i can't use both of my monitors.For this issue, i might need a switcher or something like A/b switcher to swap from Monitor 1 to Monitor 2 or Monitor 2 to monitor 1 again! Regarding to the situation above,do you have any suggestion or products recommend to me?What i know, Presonus do produce the Switcher call CSR-1 and Monitor Station! Are two of the above that i mention the Best choice in terms of Quality,Money and technically?S'ld the output TRS(balanced) to get better sound quality? Thanks and Appreciate!!
