Technics SA-EH790 A distinctive feature of the Technics is the ability to receive a signal from DVD devices, capable of transmitting a full effect of surround sound. Can be used as a home theater H+ is a class of amplifiers (the efficiency of amplifiers of this class is comparable to the efficiency of class G amplifiers). High-quality 6-channel amplifier on a chip - RSN311W64 TUNER / AMPLIFIER - Amplifier block 790 Output power (both channels, left and right) Stereo reception mode: DIN 1 kHz THD 1% / 6 Ohm (HIGH) 2x25 W 100 Hz THD 1 % / 8 Ohm (LOW) 2X45 W RMS 1 kHz THD 10% / 6 Ohm (HIGH) 2x35 W 100 Hz THD 10% / 8 Ohm (LOW) 2x65 W PRO LOGIC mode DIN FRONT 1 kHz THD 1 % / 6 Ohm (HIGH) 2X25 W 100 Hz THD 1 % / 8 Ohm (LOW) 2x45 W SURROUND 1 kHz THD 1% / 8 0M 2x30 W CENTER 1 kHz THD 1 %/8 Ohm 60 W RMS FRONT 1 kHz THD 10%/6 Ohm (HIGH) 2x35 W 100 Hz THD 10%/8 Ohm (LOW) 2x65 W SURROUND 1 kHz THD 10%/8 Ohm 2x40 W CENTER 1 kHz THD 10%/8 Ohm 80 W PMPO 1 kHz /HIGH 6 Ohm, LOW 8 Ohm, CENTER 8 Ohm, SURROUND 8 Ohm 3000 W Dimensions and weight: 1. Spectrum analyzer block Sound processor (size/weight): – 1.5 kg. Dimensions (w / h / d). 293x89x270 mm 2. Tuner/amplifier block (size/weight): – 5.2 kg. Dimensions (w / h / d). 293x118.5x345 mm Total harmonic distortion: 0.1%/6 Ohm Load impedance: front MF/HF: 6 Ohm, LF: 8 Ohm center: 8 Ohm rear: 8 Ohm Power consumption: 190 W Output power of one channel: front MF/HF: 25 W front LF: 45 W center: 60 W rear: 30 W FM tuner range: 87.5 – 108 MHz AM tuner range: 520 – 1630 kHz 3. CD changer/CD player SL-EH790 (size/weight): – 2.2 kg. Readable formats: CD-R/RW, CD-DA, WMA, MP3 Dimensions (w/h/d). 293x89x288 mm 4. Cassette deck unit (size/weight): – 2.1 kg. Dimensions (w/h/d). 294x118.5x281 mm The cassette deck was the same for all models, there was no point in changing anything in this unit, so this unit was included with all models. The total weight of all units is 11 kg. Acoustics: SB-DV290 The weakest point in old MCs is the condition of the acoustics. It is very difficult to find undamaged speakers, especially from these MCs, since the speakers in these speakers are easily accessible to children, and the suspensions on the LF speakers are made of foam - and this material is very capricious. Acoustic system - Three-way, bass reflex type ("Bi-Amping"). The bass reflex is located at the back in the middle. (by the way, if the phase inverter is brought out to the back, then it is not recommended to place such speakers close to the wall, placement no closer than 30 - 50 cm from the walls, otherwise there will be a mutter). Speaker material - MDF 12 mm thick, front panel - plastic, removable grilles. Superwoofer - 17 cm, cone type. LF speaker - 12 cm, cone type. HF speaker (tweeter) - 6 cm, cone type. Suspensions – polyurethane foam (foam suspension) Paper diffusers Input power – nominal 60 W, maximum -80 W (Low - 60Wx2, High-120Wx2) Load impedance: Front speakers (Low - 6 Ohm, high - 8 Ohm) Dimensions (W / H / D): 240x412x259 mm Total weight of all front speakers - 5.8 kg Central speaker system SB-PC95 Frequency range: 100 - 22000 Hz (-16 dB) Sound pressure: 86 dB / W / m Power: 160 W Resistance: 8 Ohm Dimensions (WxHxD): 190x99x166 mm Weight: 1.8 kg Rear speaker system SB-PS95 Frequency range: 130 - 20,000 Hz (-16 dB) Sound pressure: 84 dB/W/m Power: 70 W Impedance: 8 Ohm Dimensions (WxDxH): 140x99x118 mm Weight: 0.9 kg Central speaker system SB-PC95. The body is made of plastic and painted gray. There is a bass reflex output on the rear panel. The front panel is covered with a decorative grille. 2-way speaker system, a pair of MF with a diameter of 80 mm and one HF with a diameter of 60 mm. The crossover frequency is 4000 Hz. Connects to the amplifier via a tulip. Rear speaker system SB-PS95. Wide-range speaker system with one speaker with a diameter of 80 mm. Plastic body. The front panel is covered with a decorative grille. Connects to the amplifier via a tulip (extended cord). 00:00 - Introduction. 00:55 - Review part 2. 05:13 - Amplifier module. 07:19 - Inputs and outputs. 09:10 - Information on serial number. 09:58 - Front acoustics SB-DV290. 12:55 - Central SB-PC95 and rear speakers SB-PS95. 15:05 - Total weight of the Technics SA-EH790 MC.
