also adjusted in the Inputs tab, as is selection of the Overkiller,
functions described in the following sections.
5.1.1.1
Overkiller
The analogue input channels include a switchable Prism Sound 'Overkiller' circuit. The Overkiller is
an instantaneous progressive limiter which protects against converter overload by a margin of up to
10dB, gently absorbing transients and allowing recording levels to be raised without risk. The
Overkillers in Titan operate identically to those in other Prism Sound converters; they can be used
with any input mode (line, mic or instrument), and their operating thresholds are automatically
adjusted for any gain setting.
The Overkillers are switched on and off in the
per-channel indication of Overkiller activity is provided both on the
meter, if the meters are in 'Input' mode), and also in the Inputs tab. Note that these indicators are
dynamic, and show when the Overkiller is actually limiting.
5.1.1.2
High-pass filter
The analogue input channels have switchable high-pass 'impact filters', which roll off below 80Hz.
These are most useful in mic input mode, in removing unwanted low-frequency content. The filters
are also available in instrument and line modes, which can be useful if, for example, external
microphone pre-amplifiers without filters are used.
The filters are switched on and off in the
In channels 1 and 2, the filters can also provide an RIAA de-emphasis filter selectable as an
alternative to the high-pass filter, allowing them to be used with vinyl decks. The RIAA filter is aligned
to have a gain of 16dB at 1kHz, so that phono cartridges fall within the sensitivity range of the
instrument inputs, as described in the
5.1.1.3
MS matrix
Each pair of analogue input channels has a switchable MS matrix. This is intended for use with
'mid-side' stereo microphones, where sum and difference signals are derived from the two input
channels creating left and right output channels. The MS matrices are available when the analogue
inputs are in both mic or line modes, allowing external microphone preamplifiers without matrixing to
be used.
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.
The MS matrix is switched on and off in the
5.1.2
Digital inputs
TOSLINK and RCA connectors accept two-channel digital audio signals in the S/PDIF format at any
standard sample rate between 44.1kHz and 192kHz. The RCA input can also automatically accept
digital audio in the AES3 (AES/EBU) format using the XLR-RCA adapter supplied.
