The RH567 is a bi‑amplified, three‑way loudspeaker system that uses Philips' Motional Feedback (MFB) principle. It incorporates a 10" woofer, a 2" dome mid‑range, and a 1" dome tweeter, with separate low‑frequency and high‑frequency power amplifiers and electronic and passive crossover networks.
The manual covers disassembly, cabinet replacement, output transistor replacement, and detailed parts lists. It also describes the power supply, automatic on/off switching, overload protection, and adjustment procedures for both low‑ and high‑frequency amplifiers, providing service technicians with the information needed to maintain and repair the system.
| Frequency Response | 27‑20,000 Hz |
|---|---|
| Enclosure Volume | 30 L (20 L acoustic) |
| Maximum Power Consumption | 150 W |
| Power Supply | 117 V, 60 Hz |
| Dimensions | 320 × 540 × 265 mm |
| Low‑Frequency Amplifier RMS Power | 40 W RMS, 4 Ω load |
| Input Sensitivity | 1‑3 V at 100 kΩ, 3‑20 V at 1 kΩ |
The system has four PHONO jacks – two inputs and two outputs.
The maximum power consumption is 150 W.
It turns the unit on when an input signal exceeds a preset level and turns it off after about two minutes of no signal.
The low‑frequency amplifier delivers 40 W RMS into a 4 Ω load.
