Jbl N7000 Schematic |work| -
For those looking to build their own N7000 from scratch or replace aging components, the following values should be used:
Signal Input (+) → L2 (0.30mH) → Midrange Output (+) ↓ C1 (3uF) → Attenuator Switch → L1 (0.20mH) → Tweeter Output (+) jbl n7000 schematic
The "7000" in the name refers to its 7,000 Hz crossover frequency. It is often compared to the (8 kHz crossover), with many enthusiasts preferring the 8,000 Hz point for the 077/2405 drivers to provide a smoother transition and better protection. Rebuilding or Modifying your N7000 For those looking to build their own N7000
The (pro model 3105 ) is a vintage high-frequency dividing network designed to integrate ultra-high frequency (UHF) drivers, such as the JBL 075 , into existing speaker systems to provide added "brilliance" in upper frequencies. It typically features a crossover point of 7,000 Hz . Schematic & Technical Composition It typically features a crossover point of 7,000 Hz
The JBL N7000 was primarily designed to operate with a 7,000 Hz (7 kHz) crossover point. It was frequently paired with ultra-high-frequency transducers, such as the famous JBL 075 bullet tweeter, to augment systems using full-range drivers or mid-frequency horns. 7,000 Hz (7 kHz)
The JBL N7000 crossover is a masterclass in minimalist, effective audio engineering. Whether you are troubleshooting a vintage original or sourcing fresh air-core inductors and film capacitors to build a replica from scratch, maintaining the precise component values ensures your vintage high-frequency drivers perform exactly as the engineers at James B. Lansing intended.
The JBL N7000 schematic is a testament to the engineering excellence and design philosophy that underpins this remarkable amplifier. The design team at JBL carefully considered every aspect of the amplifier's design, from the selection of components to the layout of the PCB, to create a product that would meet the demands of professional users and audiophiles alike.
