Zeta Zero preamplifier
ULTRA-linear ultra low noise 6 channels PREAMP ZETA ZERO
This state of the art audio+video pre-amplifier which has 2 independent multi format audio+video channels for multi channel home systems.
It is perfect for any combination of your two multi audio-video signal sources i.e.: SACD, Blue ray, DVD, CD, TV, Stream player, satellite TV receiver etc.. So You may connect in to this preamp the signal from any your two sources.
Extremely easy to use. User friendly design- only simple 4 buttons, one volume knob+ remote control and NO complicated digital sub-menu at all ! You may start to listen your music with fantastic audio quality or watch a favourite film in one second!
Each of these two channels has 3 video inputs (via component)+6 inputs of extremely low noise audio for L, R, back L, back R sub woofer, central speakers- for any home cinema 5.1 and stereo installation.
Build on the best available world class discrete components and amplifiers (for example Linear audio, Thach OPA etc. usually present only in professional and measurement or medical staff). What is very important there is NO any digital conversion in audio circuit! So we have got the highest possible dynamic and perfect clear famous "analog sound". All electronics based exclusively on hi-end analogue technologies, concepts and ultra low noise components.
- So You may connect to This Pre-amplifier any two multichannel audio+video sources (each may has up to 6 audio outputs+ video via component or composite) for example Blue Ray, TV sat, DVD, CD, SACD etc.......
- The 1176 preamp has ability to decode 2 (stereo) or 6 (home cinema) input channels from any source to: 6 or 4 or 2 outputs ( your amplifiers and as many loudspeakers). So it decodes from 6,(4),(2) to 6,(4),(2)
- All functions and loudness is additionally controlled by a hand remote control unit.
- All internal architecture is purely and ONLY Analogue- No AD or DA converters in audio channels !
- If you have 6 channels source but 4 amps +4 main loudspeakers system (or simple stereo- 2amps+2 main loudspeakers) the pre amp's 1176 internal audio matrix properly decodes all 6 multichannel's input signals from your source (including sub-woofer and central speaker signal )to your loudspeakers and in effect you do not loose sub-bass and central channel signals .
- All XLR inputs and outputs are electricaly isolated , symmetrized by only real transformers, and without any active electronics added to it. other saying- All process of symmetrization(balansing) is going only on passive high class audio transformers).
- If you have only stereo CD or SA-CD but you want to use all 4 speakers, preamp 1176 can create and send your source stereo signal to all your four main speakers (L, R BL, BR) . So you are inside the sound stage not at the front of it . This mode is in effect much better on film music or instrumental music than only 2 channel.
- The electrical and mechanical design is based on TWO INDEPENDENT real solid steel boxes: one -only for all digital drivers and digital controls, display etc. and power supply, and the second heavy real steel box ONLY for AUDIO and VIDEO electronics. So it has got incredible and great isolation of any hum and AC power noises into audio tracks. So in effect it has fantastic dynamic close to 140 dB.
- All commutation of audio signals is made ONLY on vacuum switches and absolutely NO any active semiconductor switches are present in a audio chain, what gives perfect quality and no generation of any distortions or noises (noises and distortions are typical for semiconductor audio switches, does not matter how good switches are). So in effect the pre-amplifier has incredible low level of noise and distortions. Is extremely "quiet". As example: The system build on 5000 Watts RMS amplifiers connected to totally "opened" (the loudness knob turned for maximum) preamp 1176 is totally quiet- there is NO audible noise or hum from loudspeakers!
- Very useful "Ultra-dynamic" function restores more natural dynamic of the recording- usually heavy compressed by young sound engineers in their studios and this function for example makes nicely quieter some speakers voice in voice track of cinema films. This function also gently restores natural dynamic of instruments (for example in too much compressed film music etc. ).
- The volume (loudness) control is made ONLY in analogue domain on real analogue multichannel motorized precise potentiometer. (no VCA or AD/DA converters at all in audio tracks!) .
- Video (via component) matrix with active ultra high frequency buffers-line 75 Ohm outputs amplifiers.
