Εδω και καιρο εψαχνα μια πηγη ενισχυσης για τα AKG Q701 για χρηση monitoring απο υπολογιστη.
Η αληθεια ειναι οτι εψαχνα οτι πιο απλο απλα για να ξεπερασω το θεμα της περιορισμενης εντασης της εξοδου ηχου σε συνδυασμο με το οτι τα Q701 ειναι λιγο δυσκολοδηγητα ακουστικα.
Κατεληξα τελικα στο Racoon SG-300 24Bit / 96KHz USB Decoder Tube Headphone Amplifier
Features:
– Built-in high performance 24bit/96kHz USB DAC
– PSVANE 12AT7-T premium quality tube included. For those who don’t know, Psvane is actually marketed as a premier tube brand from Shuguang. One Psvane 12AT7 tube price usually pretty high
– Startup and shutdown time delay circuit protection
– 6.5mm (1/4”) headphone output for high impedance headphones
– 3.5mm (1/8”) headphone for low impedance headphones
– Will drive 2 pair of headphones simultaneously
– RCA out for use as a preamp to amplifier or active speakers. (NOTE: Can also be used to power smaller passive speakers)
– 24 bit/96kHz decoding
– Supports tube rolling (12AT7, ECC81, 6201, GT-12AT7, 6C22D etc. etc. )
– USB or RCA line-in selection from front panel
– High quality components include Alps, WIMA, NOVER etc.
– Gold plated RCA jacks
– Tube is active from the RCA input as well as the USB input
– Will support headphones from 8 – 1000 ohm impedence
Specifications:
– Inputs: USB and RCA
– Outputs: 6.5mm and 3.5mm headphone out, RCA stereo out
– Decoder Chip: Cirrus Logic CS4398
– D/A Conversion Chip: Tenor TE7022L
– Decoder Input Impedance:15K ohms
– Output Impedance: 10 ohms
– Amplifier: TI TPA6120A2
– Output Power: 100mW to 2.7W
– Input Sensitivity: 400mV ± 50mV
– Headphone Impedance Range: 8 – 1000 ohms
– Volume Control: Alps
– Frequency Response:
– 9HZ-160KHz (-3dB)
– 30Hz-30kHz (-0dB)
– SNR (Typical):> = 90dB
– THD + N, 1kHz: <0.3%, 100mW into 25 ohms
– SMPTE IMD (intermodulation distortion): <0.3%, 100mW into 25 ohms
– Interchannel Crosstalk: >55dB, 1kHz
– Net Weight: 0.5kg
– Dimensions: L104mm * H 62mm x W92mm
– Power Adapter: 220VAC to 12VAC included
Να και το review ενος χρηστη αλλα φυσικα θα μεταφερει αποψη και ο Νικος που το ακουσαμε παρεα.
