GECKO® C.R.I.S.T.A.L.® Technologies

C.R.I.S.T.A.L.® Master Audio

Crisp Resolution Integrated Stereo Audio Line (C.R.I.S.T.A.L.®), started out as an audiophile stereo mastering and encoding technology (better known as C.R.I.S.T.A.L.® Master Audio) developed by Daniel Foo, founder of GECKO MUSIC GROUP. It enables music file that is being converted and encoded with this technology sounding like the master source itself, if not better. The C.R.I.S.T.A.L.® Master Audio technology involved an ultra-wide dynamic spectrum enhancement for the original expressions of music, without altering or losing its original tonality and values, achieved based on pulse amplitude modulation (PAM) theory.

The C.R.I.S.T.A.L.® technology allows lossless conversion to major frequencies of 32, 44.1, 48, 88.2, 96kHz and higher across different bit rates and file formats. On a regular disc, the encoding stage involves a propriety-burning technique that has the rate of more than 2.8224 Mbps/Ch.

C.R.I.S.T.A.L.® Master Audio technology enables unity power factor and accurately-controlled amplitude modulation through f(x,t) = 1.00*sin(2*Π/0.10*(x-1.00*t)) and g(x,t) = 1.00*sin(2*Π/0.11*(x-1.00*t)), resulting in natural sound clarity with minimum loss over full spectrum of the reproduced audio waveform.

C.R.I.S.T.A.L.® WaveGuide Technology

GECKO® loudspeaker uses proprietary engineering designs to produce a huge amount of high-fidelity sound and very wide coverage from smaller power rating loudspeaker. Most of these designs revolve around the use of in-phase acoustic energy dispersion control, which GECKO® named as C.R.I.S.T.A.L.® WaveGuide. These designs allow compact enclosures and use of lower power consumptions (high-efficiency). The theory behind the use of this design choice is an essential and defining element in the REVELATION SLA 812RA/818WA line array, REVELATION SR 618RA subwoofer, REVELATION SR 615RF, REVELATION SR 612RF, and REVELATION SR 606R loudspeakers. C.R.I.S.T.A.L.® WaveGuide comprises of the proprietarily engineered horn, drivers, and electronics circuits.

Example 1: Actual example of C.R.I.S.T.A.L.® WaveGuide's coverage in action. Although the physical horn on the REVELATION SR 606R 6.5” loudspeaker has 90° (H) x 60° (V) coverage angles, the actual coverage is way beyond those angles. What you are watching and hearing now is live video (and sound) recorded on an iPhone X.

Example 2: Actual example of C.R.I.S.T.A.L.® WaveGuide and Audiophile technology being used for indoor choir application. The choir singing was picked up using a pair of GECKO® SATELLITE SRM 2020 C.R.I.S.T.A.L.® Audiophile condenser microphones, and sent into a 2 x 100W @ 8 Ohms GECKO® EXODUS ATOM MXR 808A C.R.I.S.T.A.L.® Audiophile powered mixing console, and finally transmitted to the congregation through a pair of GECKO® REVELATION SR 606R 6.5” loudspeakers. What you are watching and hearing now is live video (and sound) recorded on an iPhone 6S Plus.

Example 3: Actual example of C.R.I.S.T.A.L.® WaveGuide for outdoor application. The singing was picked up using the GECKO® SATELLITE SCM 1820S active C.R.I.S.T.A.L.® Audiophile condenser microphone, while the guitar was through a GECKO® AYERS ROCK C.R.I.S.T.A.L.® Audiophile DI, both lined into a 2 x 100W @ 8 Ohms GECKO® EXODUS ATOM MXR 808A C.R.I.S.T.A.L.® Audiophile powered mixing console, and finally reproduced through a pair of GECKO® REVELATION SR 606R 6.5” loudspeakers. What you are watching and hearing now is live video (and sound) recorded on an iPhone 5S.

C.R.I.S.T.A.L.® Audiophile PreAmps

The circuitry emulates what C.R.I.S.T.A.L.® Master Audio does. Mostly deployed on GECKO® mixing consoles and peripherals.

GECKO® C.R.I.S.T.A.L.® Acoustic Adaptation Processor (GCAAP)™

The circuitry automatically calculates the needed SPL and amount of in-phase acoustic energy dispersion. Mainly use on GECKO® REVELATION REVELATION SLA 812RA/818WA line array.

C.R.I.S.T.A.L.® Audiophile Class-H

Engineers and audiophiles have one thing in common when it comes to amplifiers. They want a design that provides a strong balance between performance, efficiency, and cost.

Class-H is quest for improved efficiency over the classic Class-AB, Class-D and Class-G amplifiers. Class-H amplifiers take steps further creating an infinitely variable (analog not digital) supply rail (they are sometimes called rail trackers), achieved by modulating the supply rails so that the rails are only a few volts larger than the output signal "tracking" it at any given time. The output stage operates at its maximum efficiency all the time. This is due to the circuit ability to keep the rail transistors (T2 and T4) in cutoff until a music voltage peak is of a sufficient magnitude to require the additional voltage from the + and -80V supplies. See figure below.

The Class-H amplifier can actually be thought of as two amplifiers in series. In the schematic example shown by the figure, + - 40V rail amplifiers can produce about 100 Watts continuous into an 8 Ohms load. If Vout music signal is operating below 40 Volts, the amplifier only has the losses associated with a 100W amplifier. This is because the Class-H upper device T2 and T4 are only used when the music signal is between 100 and 400 Watts output. The key to understanding this efficiency without churning the actual numbers is that we have a 400 Watts capable amplifier but with the efficiency of a 100 Watts amplifier. This is because the wave forms of music contain long periods under 100 Watts and contain only brief bursts of up to 400 Watts instantaneous; in other words, the losses at 400 Watts are kept minimal.

GECKO® deploys 2, 3, 4, and 16 tiers C.R.I.S.T.A.L.® Audiophile Class-H designs on its products. Each tier represent an audio “cell” or "band" over a sound spectrum. Example: 16-tier means an audio spectrum is being process by 16 independent cells or bands, thus the very high audio accuracy and performance efficiency.
