A second phono cartridge of the same high impedance type Main Outputs can be added in parallel by using a pair of Y adapters The two pairs of main outputs connected in parallel are dc (Switchcraft 330FlPI or equivalent). coupled to the preamplifier output. The SP5200 delivers up to 8.7 V rms before clipping, into any load of 1,000 ohills or higher. -
