External connection options

XLR and Cinch are used for historical reasons for digital connections. Back then, they simply eased the transition from analog to digital. However, these connectors should be obsolete by now, especially in light of higher sampling rates. Therefore, we use RJ45 from the world of networks, just like a few manufacturers of large digital mixing consoles, but with sturdy Ethercon with additional connectors similar to XLRs. This format has the perfect characteristics for this purpose, because it is designed for transmitting signals up to several hundred megahertz and thus provides very high precision for digital audio. All devices in the afi series are therefore offered with RJ45 Ethercon connections.

Because devices of other manufacturers still use the conventional formats, we offer a broad selection of adapter cables and adapter boxes to change to formats used by many different devices. In the case of the symmetrical AES/EBU, this simply means a cable with two different connectors or an adapter box with XLR on one side and an RJ45 Ethercon jack on the other. In the case of the asymmetrical SPDIF, there are small adapter boxes that plug in directly to the source device or the DAC. A BNC connector is permanently installed on one side (useable as a dual BNC and with a Cinch plug-in adapter). There is an RJ45 Ethercon connector on the other. The cable section is then bridged with RJ45-RJ45 Ethercon cables.

In the case of symmetrical AES/EBU connections, there is at least an XLR connector with sub-optimal impedance adjustment on one side, but this is optimised with regards to shielding from HF interference. Generally, the problem with asymmetrical connections is that the shield contaminated with HF interference is part of the signal conductor. If the external device has no symmetrical connections, then the problem cannot be fully avoided, but the asymmetrical cable section in our solution will limit this problem and thus keep the influence of HF interference on the signal quality to a minimum. Moreover, the effective cable length between the 110:75 conversion point and the Cinch is too small to produce reflections due to the maladaptive Cinch connectors on the external device. In both cases, symmetrical and asymmetrical, these measures lead to an audible improvement of the quality in the DAC compared to conventional connections.
