CLARO halo is designed
to deliver the best audio quality for headphone users including
high impedance
headphone owners. This performance is carried out through
a built-in high fidelity
headphone amplifier IC. Additionally, Claro halo can deliver
its incredible audio to your existing receiver/amplifier
through its high
class RCA connectors. Upgrade your PC to a powerful and
high quality audio center which can never be matched by
onboard or other inferior sound cards!

(3) Details
Headphone
Amplifier
 TPA6120A2
- High Fidelity Stereo headphone driver from TI. Each output
goes to stereo headphone, where the listener enjoys crisp,
clean music.
Therefore, users can experience hi-fi
stereo without the need for an external amplifier.
Claro halo design excellently provides the output to high impedance headphone up to 600ohm. A jumper switch for the high impedance headphone setting is on the board ("HIGH" or "LOW")
Note: DO NOT CONNECT
LOW IMPEDANCE HEADPHONE (under 32ohm) WITH "HIGH" SETTING.
Toshin
Kogyo audio capacitor
 High grade for audio capacitor(UTSJ type) from
Toshin
Kogyo is used
for analog output (Headphone and RCA ).
Panasonic
- Metalized Film Capacitor
Claro halo uses high grade metalized film capacitors for
both opamp and headphone amp IC ports to ensure noise-free ananlog output.
Samyoung
- mass storage Capacitor
Mass storage capacitors and protection circuits deal with
electronic shock and noise effectively. They control in-rush
current to be gradual increase and decrease for fade-in
and fade-out. This protects
monitor speakers and headphones from being damaged by the
"pop-noise" when you turn on and off the system.
Swappable
OPAMP socket
 The each polarity signal produced by AK4396 goes to 2 dual opamps. In those dual opamps, each opamp handles only
one polarity, either positive signal or negative. Then both
exclusively amplified positive and negative signals are re-assembled and goes
to another opamps for second amplification.
This design maximizes the
feature of AK4396DAC and it also dramatically improves stereo-
talk.
It is recommended to swap all four opamps for your
preferred analog sound color. Factory installed opamps are 4580
(JRC).
If you choose to swap only two, they must be U9 & U10
(They are marked on PCB of Claro halo) * See detail
High
Quality RCA connectors
 High quality
RCA connectors are mounted by nuts and lock washers to ensure
rigid installation and endurance.
Advanced
Front Panel Audio support
 You
can enjoy headphone amplifier output on Front Panel Audio
on your PC case. Claro halo provides Intel standard (AC97) Front
Panel Audio pin for your PC case. All analog outputs will
be muted when you connect headphone on Front Panel Audio
of your PC case. And we provide a jumper switch to disable the muting feature. And
users can connect a second microphone without
any reduction of input signal level
* See Front Panel Audio Usage
MIDI
connector
 For
external MIDI connector. The optional connector cable is
avaialble for MIDI in/output.
Please see
CA2 cable.
XT
(optional) connector
 Claro
halo provides multi-channel (5.1) digital by optical outlet,
but if you need to extend analog output from 2ch to 7.1ch,
we have extension device, XT.
Please see XT
2pin
connector for digital input and output
 2pin
connector for coaxial digital input and output. CA1
cable (2pin one end, coaxial the other end) is available.
See CA1
cable.
For supporting cables or XT, see Accessories

Claro halo
 Dolby Digital Live: A real-time encoding technology, Dolby
Digital Live converts any audio signal into a Dolby Digital bit
stream (48kHz at 640Kbps). Dolby Digital Live provides a
single cable connection (via coaxial or optical) to your Dolby
Digital enabled surround sound system.The real-time
interactive capabilities of Dolby Digital Live technology are
ideally suited to PCs because it reproduces audio cues and effects that follow the on-screen
action, transforming game play into an exciting and realistic entertainment.
 Dolby Headphone technology allows users to listen to music, watch movies or play video
games with the dramatic surround effects of a 5.1-channel soundtrack through any set of
headphones. Best of all, "listener fatigue," a phenomenon commonly associated with
headphone playback, is replaced by a spacious, natural sound field that listeners can enjoy
for hours.
 DTS INTERACTIVE: A real-time encoder that takes any LPCM
(2 channel or more) and encodes it into DTS bit stream (48kHz
at 1.5 Mbps). DTS INTERACTIVE provides a single cable
connection (via coaxial or optical) to your DTS enabled surround
sound system. stereo or multi-channel (up to 5.1)audio sources are
re-encoded into a DTS audio signal and sent out from the"Claro halo" to any DTS enabled system such as, powered PC speakers, an A/V receiver or
any other DTS- compatible surround decoder sound system. The installation process is simple
and eliminates the clutter, tangles, and cost of multiple analog cables
