Prism Sound Titan USB Audio Interface

Prism Sound Titan USB Audio Interface with DANTE front

The Prism Sound Titan is a USB Audio interface offering Prism’s legendary sound quality, 8 analogue I/O, 8 Digital I/O and MDIO slots for optional digital cards.

Prism Sound Titan USB

The Prism Sound Titan is a USB 2.0 audio interface based on the highly popular Orpheus and features 8 analogue I/O including 4 high-grade mic pres and 2 Hi-Z instrument inputs, 8 optical digital I/O and 2 S/Pdif / AES I/O. The Titan by Prism sound features the same outstanding and proven performance of its predecessor but boasts in addition a MDIO slot to accommodate digital interfaces adding further compatibility including Pro Tools HDX, AES and Thunderbolt.

Titan is ideal for music and sound recording, multitracking, overdubbing, stem-based mastering, analogue summing and critical listening applications.

Titan provides Prism Sound's renowned performance, sound quality and state-of-the-art clock technology in a dedicated unit compatible with both Windows (Vista and higher, 32 and 64 bit) as well as Mac OS X 10.5 and later (Intel). Once configured with a computer, Titan can also operate stand-alone using its S/PDIF or AES3 I/O.

Like Prism’s flagship ADA-8XR and its range of converters, the Titan is a no-compromise unit featuring only the best components available to offer the best possible conversion.


Verifile is a radical new proprietary technology exclusive to Prism Sound which allows computer audio streams and recorded files to be quickly checked for a wide range of clicks, errors and dropouts, without any compromise in the audio content or any additional metadata.

Standards compliant USB interface

Prism Sound has taken on board the increasing importance of native processing power for professional users and the fact that software products for standard PC and Mac platforms have been greatly enhanced in recent years. Titan uses a USB2 interface. This is a UAC2 (USB Audio Class 2) interface supported natively in Mac, iPad, Linux and Android, and in Windows via a driver.

Multichannel Digital Input and Output (MDIO) expansion

Atlas & Titan support Prism Sound’s MDIO expansion cards, which provide alternative “host” connections. The “host” is usually a computer and the Atlas or Titan interface provides a means of connection between the host and the external analogue and digital audio I/O ports.

Without the MDIO expansion card fitted, the host connection would always be the default USB connection.

The MDIO expansion slot provides an alternative host connection. It does not necessarily disable the USB port, but in the case of the Pro Tools interface MDIO-PTHDX, the USB port is switched off when the Pro Tools interface is to be used.

Currently, only the MDIO-PTHDX expansion card is available. Others may be produced later.

Flexible Inputs and Outputs

Our customers told us that many professional users wanted a highly integrated solution with instrument and microphone inputs, and line outputs that could be used for stereo or multi-channel monitoring and/or foldback to performers. Titan offers eight analogue recording channels, eight monitoring outputs, stereo digital input and output on a phono connector plus concurrent optical digital I/O ports that can interface to S/PDIF or ADAT data formats, giving Titan a maximum capability of 18 concurrent input and output channels plus stereo headphones.

Digital Mixer

Our customers also identified a need for a unit that could provide low latency foldback to performers, particularly when tracking and overdubbing. In answer to this need, Titan has a powerful built-in digital mixer that can be configured from the host computer to provide foldback feeds to performers, each with their own stereo mix of workstation playback and any of the inputs.

Flexible Monitoring and 5.1 capabilities

Professional users demand more sophisticated monitoring capabilities and are getting used to surround sound with HDTV and DVD, so it is becoming important to support surround monitoring setups.

As well as wanting great analogue recording channels, the DAW user also needs top-quality monitoring. The eight analogue outputs on Titan allow monitor setups from multi-stereo up to 7.1 surround. Titan has a real volume knob which can be assigned to any or all of the analogue or digital outputs for use as a control room monitor control. There are two headphone amps, suitable for all types of headphones, each with its own independent volume control. As well as having its own workstation feed and mixer, the headphones can also be quickly switched across the other output pairs, which is handy for setting up.

Sample Rate Conversion and Noise Shaping

The digital output is equipped with the four Prism Sound SNS noise-shaping curves and includes Prism Sound's renowned synchronous sample-rate conversion, allowing outputs to various external devices at other sampling rates. The sample-rate converter can be used at the outputs as well as the inputs, so as well as dealing with unsynchronised or wrong-rate digital inputs, Titan can also generate, say, a live 44.1kHz output from a 96kHz session. Since Titan also includes the full suite of the famous Prism Sound 'SNS' noise shapers, you can also reduce to 16-bits at mastering-house quality.

Unsurpassed Jitter Rejection

In the 1990s Prism Sound pioneered testing of sampling and interface jitter and as a result our digital audio products deliver unsurpassed jitter rejection. Prism Sound digital audio products lock up fast and re-generate ultra-stable clock outputs. Another aspect of the traditional Prism Sound converter that is retained was the clocking - it's just as important as analogue-path considerations sound-wise. So whether it's providing a high-quality master clock for the rest of the room, or dealing with a jittery clock from outside, Titan is as rock-steady as its forbears.
