Sample Rate Converters

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-2src is a state-of-the-art digital audio sample rate converter.
First introduced in January of 1994, the z-2src has gone on to become
one of the world's most widely used sample rate converters.

The z-2src is a rack-mount real-time sample rate converter which can solve a great many difficult digital audio interfacing problems. This sample rate converter features AES/EBU, S/PDIF, and optical inputs and outputs, a wide variety of output synchronization options, and the ability to generate all of the standard output sample frequencies directly or from an external reference.

In addition to serving as a sample rate converter, the z-2src can also be used as a format converter and features an audio bypass switch which leaves the audio data intact but still allows channel status bits to be manipulated. Because the z-2src is based on the AD1890 asynchronous sample rate converter chip, it also performs spectacularly as a jitter attenuator.

For those needing sample rate conversion only, without the wide array of features provided by the z-2src, we also have the z-link and z-link+ mini sample rate converters. These units have the same quality sample rate conversion as the z-2src, but at lower prices.

The z-link mini sample rate converter is based on the same sample rate
conversion technology as the z-2src.

The z-link is a palm-sized, real-time sample rate converter. It provides an affordable, high-quality solution to a great number of digital audio interfacing problems. For example, you can use the z-link to sample-rate convert the 48 kHz output from a Yamaha ProMix 01 to a 44.1 kHz signal which can be fed to the input of a CD-R machine digitally. Or, you can use the z-link to convert the 44.1kHz output of a CD transport to 48 kHz for use in digital audio-for-video applications.

The z-link also features a professional/consumer output switch which allows you to set the output channel status as desired. This is important when used with most consumer and some professional DAT machines (such as the Panasonic SV3700), which demand to see the appropriate channel status bits when recording digital inputs. Because the z-link is based on the AD1890 asynchronous sample rate converter chip, it also performs spectacularly as a jitter attenuator.

An externally-synchronizable version of the z-link, the z-link+ is also available.

The z-link+ mini sample rate converter is an enhanced version of the z-link and is based on the same sample rate conversion technology as the z-2src. The z-link+ has the same core features as the z-link but adds an external synchronization loop, which allows the z-link+ to have its output sample rate locked to an external AES/EBU or S/PDIF digital audio signal.

The z-link+ is a palm-sized, real-time sample rate converter. It provides an affordable, high-quality solution to a great number of digital audio interfacing problems. For example, you can use the z-link+ to sample-rate convert the 48 kHz output from a Yamaha ProMix 01 to a 44.1 kHz signal which can be fed to the input of a CD-R machine digitally. Or, you can use the z-link+ to convert the 44.1kHz output of a CD transport to 48 kHz for use in digital audio-for-video applications. The z-link+ also features a professional/consumer output switch which allows you to set the output channel status as desired. This is important when used with most consumer and some professional DAT machines (such as the Panasonic SV3700), which demand to see the appropriate channel status bits when recording digital inputs. Because the z-link+ is based on the AD1890 asynchronous sample rate converter chip, it also performs spectacularly as a jitter attenuator. The z-link+ is quite useful in application where digital audio signals need to be sample rate converted and/or synchronized. For example, D2 digital composite video has a digital audio sample rate of 48 kHz. However, the 48 kHz input digital audio signal must be locked exactly to the D2 video machine's sample rate reference. For example, the D2 machine would not be able to record on its digital audio input the output of a 48 kHz DAT machine that was free-running on its own internal sample rate reference. The z link+ is useful in this situation; the D2's digital audio output can be sent to the z-link+'s external sync input and the z-link+ will, in turn, use this reference to generate a digital audio output which is in sync with the D2 machine.

The z-link96 mini sample rate converter is based on the same sample rate conversion technology as the z-3src.

The z-link96 is a 24-bit 96 kHz version of the z-link. An externally-synchronizable version of the z-link96, the z-link96+ is also available.

The z-link96+ mini sample rate converter is based on the same sample rate conversion technology as the z-3src.

The z-link96+ is a 24-bit 96 kHz version of the z-link+.
