{"product_id":"audison-thesis-hv-venti-2-kanal-verstaerker","title":"Thesis HV venti","description":"\u003cp\u003eThesis HV venti is a 2-Channel Amplifier from Audison with dual-mono construction and four synchro-PWM power supplies. The MOSFET-BJT hybrid configuration uses discrete IGBTs, two Hitachi DMOS, and two pairs of complementary Sanken Power BJTs, each designed for 30 A peak current and 200 W power loss. The Class A preamplifier and driver is symmetrically built up to the driver outputs, with 90 V supply for the front-end stage and two separate channels. A separate 150 V power supply is thermally stabilized and biased in Class A. The symmetrical input combines a complementary JFET differential and a complementary BJT differential; the voltage amplifier is implemented as a cascode with a buffer. The output power is 400 W x 2 at 4 Ohm, 800 W x 2 at 2 Ohm, and 900 W x 1 at 4 Ohm at 14.4 VDC and 1% THD, with a total RMS power of 1600 W. The bandwidth is 4 Hz to 75 kHz, the S\/N ratio is 100 dB, and the damping factor is 80. Additional features include fully relay-switched signal routing, exclusively discrete components, Dual Power and Bias Selector functions, Hi and Low Level inputs, and a 5 mm aluminum housing with two side cooling channels.\u003c\/p\u003e\n\u003cdiv\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/div\u003e\n\u003cul\u003e\n\u003cli\u003e2-Channel Amplifier\u003c\/li\u003e\n\u003cli\u003eDual-mono construction with four synchro-PWM power supplies\u003c\/li\u003e\n\u003cli\u003eMOSFET-BJT hybrid configuration with discrete IGBTs; two Hitachi DMOS drive two pairs of complementary Sanken Power BJTs (each 30 A peak current, 200 W power loss)\u003c\/li\u003e\n\u003cli\u003eClass A preamplifier and driver, symmetrically built up to the driver outputs\u003c\/li\u003e\n\u003cli\u003eFully symmetrical input circuit with complementary JFET differential (first stage) and complementary BJT differential (second stage)\u003c\/li\u003e\n\u003cli\u003eVoltage amplifier as a cascode with buffer to drive the output stage\u003c\/li\u003e\n\u003cli\u003eSeparate power supply: 90 V for front-end and channels; separate 150 V power supply, thermally stabilized and biased in Class A\u003c\/li\u003e\n\u003cli\u003eManufactured exclusively with discrete components; signal routing exclusively via relays\u003c\/li\u003e\n\u003cli\u003ePower supply on a separate board\u003c\/li\u003e\n\u003cli\u003eDual Power function to switch between Hi-Current and Hi-Power\u003c\/li\u003e\n\u003cli\u003eBias Selector to change the Class A percentage\u003c\/li\u003e\n\u003cli\u003eHi Level Input and Low Level Input\u003c\/li\u003e\n\u003cli\u003eHigh-quality Crossover module included\u003c\/li\u003e\n\u003cli\u003e5 mm aluminum housing with two side cooling channels\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/div\u003e\n\u003cul\u003e\n\u003cli\u003eChannels: 2\u003c\/li\u003e\n\u003cli\u003eAmplifier Class: A-Class\u003c\/li\u003e\n\u003cli\u003eHi Level Input: Yes\u003c\/li\u003e\n\u003cli\u003eLow Level Input: Yes\u003c\/li\u003e\n\u003cli\u003eDigital Input: No\u003c\/li\u003e\n\u003cli\u003eSupply Voltage: 11–16 VDC\u003c\/li\u003e\n\u003cli\u003eIdle Current: 4.2 A\u003c\/li\u003e\n\u003cli\u003eIdle Current when Off: 0.006 mA\u003c\/li\u003e\n\u003cli\u003ePower Consumption at 14.4 VDC, 2 Ohm, maximum music power: 90 A\u003c\/li\u003e\n\u003cli\u003eRemote IN: 7–16 VDC, 1 mA\u003c\/li\u003e\n\u003cli\u003eDistortion (THD) @ 100 Hz, 4 Ohm, 70% rated power: \u0026lt; 0.05 %\u003c\/li\u003e\n\u003cli\u003eBandwidth (-3 dB, 2 VRMS, 4 Ohm): 4 Hz – 75 kHz\u003c\/li\u003e\n\u003cli\u003eSignal-to-Noise Ratio (A-weighted @ 1 V): 100 dB\u003c\/li\u003e\n\u003cli\u003eDamping Factor (1 kHz, 4 Ohm): 80\u003c\/li\u003e\n\u003cli\u003eInput Sensitivity (Pre-In high): 0.25 – 1.6 VRMS\u003c\/li\u003e\n\u003cli\u003eInput Sensitivity (Pre-In low): 1 – 7 VRMS\u003c\/li\u003e\n\u003cli\u003eTotal RMS Power: 1600 W\u003c\/li\u003e\n\u003cli\u003eOutput Power (RMS) @ 14.4 VDC, 1% THD, 2 channels at 4 Ohm: 400 W x 2\u003c\/li\u003e\n\u003cli\u003eOutput Power (RMS) @ 14.4 VDC, 1% THD, 2 channels at 2 Ohm: 800 W x 2\u003c\/li\u003e\n\u003cli\u003eOutput Power (RMS) @ 14.4 VDC, 1% THD, 1 channel at 4 Ohm: 900 W x 1\u003c\/li\u003e\n\u003cli\u003eAdjustable Crossover: No\u003c\/li\u003e\n\u003cli\u003eInput Type: Pre IN L\/R (ABS)\u003c\/li\u003e\n\u003cli\u003eOutputs: Pre OUT (pre in bypass) L\/R (ABS)\u003c\/li\u003e\n\u003cli\u003eFilter Pass A: High-pass \u0026amp; Low-pass stereo 45 \/ 55 \/ 65 \/ 80 Hz, 12 dB\/Oct.\u003c\/li\u003e\n\u003cli\u003eFilter Pass B: Low-pass mono 45 \/ 55 \/ 65 \/ 80 Hz, 24 dB\/Oct.\u003c\/li\u003e\n\u003cli\u003eFuse: 100 A\u003c\/li\u003e\n\u003cli\u003eOther Functions: Demo mode ext. supply: 12 VDC, 600 mA; Ext.
