retro TRIO KA-7006 Adopts all stages direct connection + pure complementary

Description: Product descriptionStereo integrated amplifier with all stages directly connected + pure complementary circuit. The power amplifier section combines an all-stage direct connection circuit from the first stage to the final stage, with no interstage coupling capacitors removed, and a pure complementary circuit using the PNP-NPN Darlington method in the output stage. Furthermore, the ±2 power supply scheme using the first stage differential scheme is adopted.As a result, various characteristics in the bass range have been thoroughly improved, and stable output has been obtained across the entire audible frequency range.A limiter type protection circuit is used to protect the transistor, and a relay is used to protect the speaker and prevent shock noise when turning the power on/off.When the output terminal is short-circuited, the limiter level drops within 100m・sec to protect the transistor.The three-stage direct connection system of the first stage differential circuit is adopted as an equalizer.DLOA (dual low noise operational amplifier) is adopted as the tone control circuit.DLOA consists of a first-stage differential amplification, a buffer, a 3-stage class A drive, and a pure complementary circuit, which achieves high dynamic range, high input impedance, better power utilization, and low impedance and distortion. I'm doing it. Also, shock noise is suppressed because the DC current at the output end is 0V.Furthermore, a tone control defeat switch is provided.A subsonic filter and a rumble filter are used as the low filter.In addition, a scratch filter is used as the high filter. Equipped with audio muting and mode selector.Equipped with 4ch input/output terminals.Equipped with a microphone terminal.●Main specificationsModel: Solid state stereo integrated amplifierEffective output20Hz-20kHz, both channels operation: 50W+50W(8Ω)1kHz, single channel operation: 90W/90W (4Ω)65W/65W(8Ω)Both channels operation: 70W+70W(4Ω)55W+55W(8Ω)Music power (IHF) 250W (4Ω)160W(8Ω)Total harmonic distortion rate (8Ω) 0.3% (at rated output)0.05% (rated output -3dB)Cross modulation distortion rate 0.3% (at rated output)0.05% (rated output -3dB)Output bandwidth (IHF) 6Hz to 45kHzResidual noise (8Ω) 0.5mVDamping factor (8Ω) 30Optimal load impedance 4Ω to 16ΩInput sensitivity/impedance Phono1, 2: 2.5mV/50kΩTuner, Aux, Tape play A, B: 150mV/50kΩ Mic:2.5mV/50kΩ4ch input:150mV/50kΩSN ratio (IHF-A network) Phono1, 2:84dB (input 5mV)Tuner, Aux, Tape Play A, B: 95dB4ch input:95dBOutput level/impedance Tape rec Pin:150mV/50ΩTape rec Din:40mV/70kΩ4ch out:150mV/50ΩMaximum allowable input (1kHz, RMS) Phono:250mVFrequency characteristics Tuner, Aux, Tape play: 10Hz - 20kHz +0 -0.5dBPhono:RIAA deviation ±0.5dBTone control Bass:±10dB(100Hz)Treble:±10dB(10kHz)Filter Low:20, 40Hz, 12dB/octHigh: 7kHz, 6dB/octaveLoudness control (Volume-30dB) +8dB(100Hz)+3dB(10kHz)AC outlet power switch interlocking: 2 systemsPower switch non-interlocking: 1 systemPower supply voltage AC100V, 50Hz/60HzRated power consumption (Electrical Appliance and Material Control Law) 140WExternal dimensions Width 435x Height 157x Depth 300mmWeight 11.8kg★The condition of the product is slightly scratched and dirty.★There are scratches on the volume and other switches.For "remote delivery areas", additional fees will be charged.
