CD・MDレシーバー — The CQ-VX3500 sits at the top of Panasonic's early-2000s 2-DIN VX line, and it's the DSP that earns it the badge. Behind the face is a proper 2-in / 4-out digital sound processor with seven space modes and a 7-band equaliser running 80 Hz to 10 kHz, adjustable ±12 dB across thirteen steps — genuinely fine-grained for a factory-replacement deck of the period. CD and MiniDisc both live in the same chassis, there's a real AUX input on board (2 V, 10 kΩ) so a phone or a Bluetooth module drops straight in, and the pre-out runs a healthy 2 V into ≤600 Ω for anyone bolting on outboard amps. 41W × 4 keeps the doors honest until then. Peak-era Panasonic — tuned rather than just loud. Bluetooth is included, and tested. Amplifier has been tested successfully. CD has been tested is working successfully. MD has been tested is working successfully. Harness Included.
