The z-3src 24-bit/96 kHz sample rate converter is the long-awaited follow-up to the z-2src, one of the world's most widely used sample rate converters.
The z-3src shares all of the same features as the z-2src but adds the ability to handle input and output sample rates up to 96 kHz at a resolution of 24 bits. Furthermore, the z-3src features an output wordwidth control, allowing the user to select 16, 20, or 24-bit output. The z-3src is based on the ground-breaking CS8420 sample rate conversion chip from Crystal Semiconductor, which gives the z-3src unprecedented measured and sonic performance in asynchronous sample rate conversion.
The z-8src is an eight-channel variant of our flagship z-3src. The z-8src boasts the same audio performance to the z-3src, with the only significant differences being the inclusion of eight channels' worth of identical sample rate conversion and deletion of a few features in order to house the unit in a single rack space. The benefit of using the z-8src is that all output channels get locked to a single clock reference; it's like using four z-3srcs all synchronized to the same reference.
The z-8src can accept inputs between 32 kHz and 96 kHz at up to 24 bits and can output any sample rate between 32 kHz and 96 kHz by using an external AES11 sync reference. The unit also features a Fs/2 "flywheel" where the output sample rate is generated by dividing the sync reference's sample rate in half. You can also manipulate the output channel status bit and an output wordwidth control allows you to apply TPDF dither and produce output wordwidths of 16, 20, or 24 bits.
