Καθως σερφαριζα αμεριμνος στο ebay, επεσα επανω σε αυτο το μηχανακι, το οποιο και ποσταρω εδω γιατι πιστευω πως ειναι η καταλληλη ενοτητα για να συζητηθει. Αυτο που μου κεντρισε το ενδιαφερον αρχικα ειναι οτι ειναι OTL, ενισχυτες τους οποιους εχω ιδιαιτερη αδυναμια. Το δευτερο και πιο σημαντικο, ειναι οι μετρησεις του, που ειναι αν μη τι αλλο, θεαματικες!
Προκειται για ενα κιτ ενισχυτη ακουστικων απο μια Τσεχικη εταιρια την οποια πρωτη φορα τη βλεπω, οχι οτι εχω και μεγαλες γνωσεις απο εταιριες βεβαια. Τα χαρακτηριστικα του μηχανηματος εδω:
General Features of ProXaudio PHX150+:
- Developed and made in Czech Republic
- OTL - Output Transformer Less design
- High quality components used, such as ALPS audio potentiometer, Vishay trimmers and resistors , capacitors from Nippon Chemicon, Wima and Siemens/Epcos
- High quality PCB`s
- All parts sourced in Europe from good distributors, NO FAKE PARTS !
- Protection for your headphones against DC voltage at the output !
- Each amplifier is hand built and fully tested prior to shipping.
- Each amplifier is supplied with a measuring protocol.
- Solder work is outstanding and clean.
- Pure class "A"
- Beautiful triode sound - we do not use TV pentodes or similar non-standard tubes.
- Deep and accurate bass, wide and clean mids with crystal-clear highs.
- Possible selection from several types of tubes for driver stage (contact us before buy if you want special grade tubes in driver stage such as NoS TESLA E88cc)
- Extreme low distortion and high fidelity sound.
- Absolutely no audible noise and hum
- Frequency response (-1dB) from 14 Hz to 200 Khz !
- Suitable for: 32-600Ω Headphones
- Simple and comfortable single-button operation.
- Power on and power off sequence controlled by microprocessor for safety and very long tubes lifespan
Driver tube stage: 6N1P
Power tube stage: 6N6P
Frequency response (+0/-1 dB): 14 Hz to 200 Khz
Absolute phase : IN PHASE
Input Impedance: 10KΩ
Output Impedance: 3Ω
Gain: 20 dB (ADJUSTABLE)
Damping factor: 100 *
Crosstalk between channels: better than -65 db
Signal to Noise (SNR) : better than -85 db
Maximum sine power : 200 mW* (sufficient for almost any Hi-Fi Headphones)
Max. Out voltage: 9V RMS*
Minimum load impedance: 24Ω
Supply Voltage: 110 / 230V
Το λινκ για το ebay εδω. Το λινκ για τις μετρησεις του μηχανηματος εδω.
Καντε εναν κοπο να το κοιταξετε και πειτε μας μια γνωμη...
