2. Deep Analysis: The "Groove" Era Engineering

3.1 Amplifier Section

The defining feature of the V702 is its amplification architecture.

• Amplifier Type: Bi-Amplification System.
  • Analysis: The system utilizes a dedicated amplifier for the woofer and a separate amplifier for the tweeter. This separation reduces intermodulation distortion and allows for more efficient power distribution to each driver.
• Total Power Output: Approximately 100 Watts (RMS) total system power (50W + 50W).
• Power Output (Per Channel):
  • Woofer Amp: 25W + 25W (at 6 ohms, 1kHz, 10% THD).
  • Tweeter Amp: 25W + 25W (at 6 ohms, 1kHz, 10% THD).
• Total Harmonic Distortion (THD): < 0.07% (standard operation).
• Frequency Response: 20 Hz – 20,000 Hz (±3dB).

Driver Configuration

• Woofer: 16 cm (6.3 inches) cone type (Polypropylene or Mica loaded).
• Mid-range: 6 cm (2.3 inches) cone type.
• Tweeter: 2.5 cm (1 inch) PET (Polyester) film dome.
• Impedance: 6 ohms (Nominal)

Amplifier & Power Specs (The Heart of the System)

The main unit (amplifier/tuner section) was the centerpiece. Sony marketed this system with "High Power" output, though ratings differ between peak and RMS. Amplifier Type: Bi-Amplification System

• RMS Continuous Power: 120 watts per channel (into 6 ohms, 1 kHz, 10% THD)
• Total RMS Power: 240 watts
• Peak Music Power Output (PMPO): 750 watts (manufacturer claim, often used for marketing)
• Dynamic Power per Channel: Approximately 140W at 4 ohms
• Total Harmonic Distortion (THD): 0.9% or less (at rated power)

Note: Like many systems of the era, the RMS power rating is conservative compared to modern standards, but the LBT-V702 was known to drive speakers loudly and cleanly.

Tone Control Specs (Bass & Treble)

• Bass Control: Variable from ±8 dB at 100 Hz
• Treble Control: Variable from ±8 dB at 10 kHz
• EQ/Surround: The unit features a Dolby Pro Logic surround sound processor (early home theater standard) with adjustable center channel delay (1 to 30 milliseconds).

3. Cassette Deck Section

For tape collectors, this unit offers serious utility.

• Type: Dual Auto-Reverse Cassette Decks
• Features:
  • High-speed dubbing (copies tapes quickly).
  • Relay Play (plays both sides of both tapes sequentially).
  • Dolby B Noise Reduction.
  • CD Synchro Recording (automatically starts the tape when the CD starts).

Complete System Specifications (Summary)

When combined, the Sony LBT-V702 offers the following user-facing specs:

• Total Power Consumption: 280 Watts (Maximum)
• Standby Power: 2.5 Watts
• Remote Control: Yes (RM-SV702 – Infrared, 28-key)
• Video Output: Standard Composite video out (for CD-Graphics – CD+G).
• Dimensions (Complete stack with wood sides): 280 mm W x 365 mm H x 485 mm D (The height increases with feet and ventilation gaps).
• Weight (Full stack, no speakers): 13.6 kg (30 lbs)

1. Amplifier Specs (TA-V702): The Power Engine

The heart of any system is the amplifier. The Sony TA-V702 utilizes a proprietary power supply system often labeled Super Power Amplifier. Note that vintage amplifier specs can be confusing (Peak vs. RMS). Here are the real specs.
