    The figure above is a simplified block diagram of the Titan audio signal paths. Titan is basically a sound card, with all inputs made available to the host computer via the USB host bus, and all outputs likewise driven from the USB host bus. However, Titan's signal paths contain a range of enhanced processing and mixing functions, which are described in the following sections.
  • Page 29: Overkiller

    Note that there is no explicit stereo width control provided in the matrix; however width can be adjusted by balancing the gains of the mid and side inputs - the gain steps of the Titan microphone preamplifiers are fine and precise. In line input mode, no fine gain adjustment is available, so if the Titan MS matrix is used with external preamplifiers, these must have fine and accurate gain control if width adjustment is required.
  • Page 30: Sample-Rate Converter

    In normal operation, the analogue outputs are fed directly with individual signals from the host PC or Mac; however, it is possible to feed the outputs from local digital mixers within the Titan hardware if desired - this is described in the Output mixers section below.
  • Page 31: Digital Outputs

    In normal operation, the S/PDIF digital outputs are fed directly with individual signals from the host PC or Mac; however, it is possible to feed the outputs from local digital mixers within the Titan hardware if desired - this is described in the Output mixers section.
  • Page 32: Word-Length

    Word-length It is possible to control the word-length of the S/PDIF output using the word-length control, uppermost in the DO1/2 strip in the Outputs tab of the Titan Control Panel app. The control operates as follows: Setting Action 24 bit All 24 bits sent to the digital output are transmitted from the S/PDIF or AES3 output.
  • Page 33: Assignable Level Control

    The output mixers are primarily intended to provide low-latency foldback or monitor mixes incorporating Titan's audio inputs in conjunction with feeds from the DAW software - since the mix is performed locally, the delay involved in passing live audio up to the host computer and back is removed.
  • Page 34: Mdio Expansion Slot

    Titan incorporates Prism Sound's new MDIO expansion slot. This allows an optional expansion module to be added, enabling Titan to connect to a host device using a different interface format from its default USB. MDIO modules of various formats will become available in the future.

    Titan's digital input or output. In the former case, the SRC simply converts any incoming digital signal of whatever sample rate to the sample rate of the Titan unit. If the SRC is in the digital output, it is necessary to specify what the output sample rate must be; furthermore, it may be necessary to lock the output rate to an arbitrary external reference.
  • Page 36 · Standby button: puts the unit into a low-power standby state. Note that the USB interface is still active in standby mode, so the Titan unit can still be recognised by the host, although its inputs and outputs are inactive. The LED in the standby button flashes to identify the unit in multi-unit setups when the 'Identify' button in the Control Panel app is clicked.

    Stand-alone operation It is possible to operate Titan without a connection to a host computer. This is done by setting up the unit as required using the Titan Control Panel app whilst it is connected to a host computer via its USB interface, then placing the unit in standby by pressing the standby button, before disconnecting the unit from the host and power source.

    ULOK (unlock) is lit when no S/PDIF carrier is detected at the selected input; ASNC (asynchronous) is lit when the incoming carrier is not locked to Titan's selected sync source. In ADAT modes, ULOK and ASNC indicators are also provided for the ADAT/SMUX inputs.

    There is also a mute button (whose function is also available by pressing the volume knob on the Titan front panel) and a numerical readout/setting box. Note that changes to the assignment of the level control can be prevented by engaging the lock button (marked with a key symbol) just above the level control.

    It is not necessary to run the Titan Control Panel app for applications to be able to use Titan; however, the app is needed if any but the most basic control of Titan's functions is required.

  • Page 48: Technical Topics

    Technical topics The following sections contain detailed discussions of various relevant technical issues. The content of these sections is not required to operate Titan, but is provided merely as background information. Stability and latency Ever since audio production has found its way inside the computer, new problems concerning issues of stability and latency have arisen.
  • Page 49: Clocking And Jitter

    Operation Manual Revision 1.00 In the case of Titan, problems of latency and stability are improved by a couple of useful features: First of all, the operator can control the buffer delays within the Mac and Windows drivers directly, irrespective of what buffering is employed by the user's particular audio software. It is generally recommended that these buffer delays are set long, in order to provide best stability.
  • Page 50 AES3 or S/PDIF receiving chip, without any further jitter filtering. Remember that none of these side-tones is present in the digital audio signal - they are caused only by jitter. The lower trace shows almost complete jitter rejection across the band by the CleverClox process in Titan. Listening experience In practice, it seems that the benefits of careful clock design are very apparent in listening tests.
  • Page 51: Dither And Noise-Shaping

    Titan and CleverClox Titan is designed to source clocks which are as stable and accurate as possible, and also with the aim of being insensitive to the quality of incoming clocks. It is designed to remove jitter from any selected reference sync source before it is used as a conversion timebase, so as to eliminate any audible effects of sampling jitter, whatever sync source is used.
  • Page 52 Titan provides a comprehensive choice of dithering and noise-shaping processes. These comprise ‘ flat’ dithering, plus a selection of four Prism Sound ‘SNS’ (‘Super Noise Shaping’) algorithms. All produce high-quality 16 bit output: the choice of which one to use is purely subjective. The four SNS algorithms are designated SNS1 to SNS4, in increasing order of the degree of shaping.
  • Page 53 SNS2 is a good starting point for most situations. The Prism Sound SNS logo shown above is found on many of the world’s finest CDs, and is recognised as a standard of technical excellence. The logo, and accompanying sleeve note, is available by contacting sales@prismsound.com.
  • Page 54: Analogue Interconnections

    Operation Manual Revision 1.00 Analogue interconnections To maintain the high sound quality of Titan, it is important to follow some basic guidelines when making analogue connections to the unit. This section discusses some things to watch out for. Cable quality Use of good-quality, heavy duty audio cables is recommended.
  • Page 55 A solution to this is the use of external 'sound cards', such as Titan, with their own enclosures and power supplies allowing adequate space, power and electromagnetic peace and quiet for the well-being of studio-quality analogue circuits.
  • Page 56: Digital Interconnections

    (the outer of the instrument input jacks, or pin 1 of the mic input XLRs). Since no dedicated terminal exists on Titan, it is usually easiest to connect the wire to the outer of one of the deck's unbalanced output connectors. In some situations, a direct connection to local mains ground may work better.
  • Page 57 Even though Titan is insensitive to incoming clock jitter, and even though it transmits very low jitter at its digital audio and clock outputs, the question of cable quality may still be relevant if Titan is transmitting to equipment which itself has poor jitter rejection capabilities.
  • Page 58 Prism Sound Titan Operation Manual Revision 1.00 digital audio use, especially at high sample rates. Prefer also the shortest cable, since (all other things being equal) loss of bandwidth is proportional to length. Maximising cable bandwidth is important in optimising AES3 and S/PDIF data integrity at high sample rates such as 192kHz, and in optimising conversion quality in systems which include poor-quality converters.
