Asynchronous SPDIF to I2S signal transfer
In order to correct timing and data speed transfer errors the TC-7535 uses a
asynchronous buffer with a length of 1024 bits to take care of time period
related errors.
Direct Coupled Line Output Stage
This allows the Caiman SEG to operate down to 1Hz. The Caiman SEG is
therefore also suitable for DVD audio application, which can go down to 5Hz
or lower.
High Current Class A-B headphone circuit
The Caiman SEG headphone amplifier circuit is designed to drive even the
latest high-end headphones and reproduce musical detail that these headphones
are capable of. A generous signal headroom overhead, low noise circuitry, and
high output current ability are key factors that make the headphone output on
the Caiman SEG a major talking point with existing owners.
LED dimming during music playback function
The Caiman SEG has a LED dimming function that can be set to operate when
there is music playing. So that way you can make sure that no LED noises can
bleed into the sound.
12 Volt power supply option
Due to the highly efficient design and low energy requirement placed on the
power supply, the Caiman SEG is capable of operating from a 12Volt battery
source. The Caiman is also an extremely energy efficient DAC. It can
therefore be powered by not only its own 12V power supply, But
also by alternative 12V sources of power such as batteries and
solar cells. The basic DAC includes a desktop power supply.
Power supply upgrades are recommended.
DC Linearizer Low Noise Filter
External DC power supplies are a known source of RF noise. Our own unique
DC Linearizer circuit transforms almost all of that RF noise into a clean DC
voltage. The result is then fed to a Low Drop Out regulator circuit. The result is
a crystal clear and warm analogue sound with excellent musical detail.

Low jitter Crystal controlled receiver chip
The Caiman SEG uses a crystal controlled receiver with one of the lowest jitter
performances possible from a receiver chip. At 50ps few other DACs can match
or surpass the Caiman SEG in terms of jitter rejection.
Simple Analogue Filter Circuit
There has been much debate as to how much damage is done to the audio signal
by the various digital and analogue filtering networks that are found in a DAC
design, and whether filters contribute to grainy high frequencies. The
technology used in the Beresford Caiman SEG relies instead on a simple HF
analogue filter that operates outside any feedback circuit and outside the audio
spectrum. This makes the Caiman SEG less prone to anti aliasing filter residues
and noise, and produces a far cleaner and detailed treble response.
Up to 32 Bit and 768fs oversampling
The current range of high-end consumer DACs chips go up to 32 bit, but only
384kHz oversampling. The Caiman SEG DAC is capable of up to 768kHz
performance.
