Tip: Holographic for Headphones
® is not based on a standard cross-feed system, as found in some high-end headphone
ampliers. Many so called ‘3D systems’ are usually DSP based. This articially eects the sound and adds unwanted reverb in order to simulate a
‘spacious‘ type of sound.
It’s true that traditional cross-feed tends to produce an ‘out of head’ sound, but with much diminished spatial components and a narrower
soundstage, sometimes almost approaching mono. Most DSP based 3D designs produce an unnatural, echo-like sound, which may initially be
impressive, but soon becomes tiring.
By contrast, Holographic for Headphones®, provides not only ‘out of head’ placement of the sound sources, but renders the whole sound
eld in a manner that strongly parallels listening to loudspeakers in a normal room, all achieved without the added reverb. This is the rst system in
commercial production to achieve this.
For Loudspeakers: (Line Outputs)
The Holographic for Loudspeakers® is an analogue matrix circuit that has two distinct functions. It
Corrects the fundamental spatial distortion in stereo recording
Increases the width of the apparent soundstage beyond the width dictated by the loudspeaker placement
OFF: Holographic is disabled (this allows the ‘direct’ sound to be judged).
+: This matrix corrects (’+’) the spatial distortion caused by the recording/mixing/mastering process and restores the
original width of the soundstage. This is the recommended default setting if the loudspeakers are already ideally placed for
imaging.
30˚+: This matrix corrects (’+’) the spatial distortion caused by the recording/mixing/mastering process and adds an
approximate 30˚ to the apparent width of the soundstage. Thus, loudspeakers with narrow placement (e.g. loudspeakers
closely located either side of a TV set) can oer a soundstage that extends beyond the left and right past the loudspeakers
and is close to the ideal placement.
