Vertere Acoustics Redline Analogue Tonearm CableRedline Analogue Tonearm Cable Redline Analogue Tonearm Cable, as with the Pulse R, allows the miniature cartridge generator to drive the phono input comfortably. The internal conductor configuration of the Redline tonearm cable is optimised for conducting the delicate phono signal with its substantial RIAA equalisation. This provides the low frequencies, recorded at attenuated levels, and the much higher level high frequencies, with an equal drive.
