Connecting Nakamichi SoundSpace 1 Speakers to Modern Audio Inputs

Connecting a Nakamichi SoundSpace 1 speaker to a modern audio input can be a daunting task, especially when faced with the unconventional use of Category 5 (CAT5) speaker wires. The logical engineers at Nakamichi chose to integrate the amplifier circuit within each speaker, making direct connection to a typical audio input nearly impossible. Let's explore why this is the case and what steps you can take to achieve your desired setup.

Why Can't You Connect Nakamichi SoundSpace 1 Speakers to a Modern Audio Input?

The simple answer is that you can't. The Japanese engineers behind Nakamichi's SoundSpace 1 speakers have used a CAT5 cable for a reason. This cable isn't just a simple connector for speaker wires; it houses capacitors that form a complex circuit, including what appears to be an active amplification system. Understanding this requires delving into the service manual and analyzing the parts list.

Understanding the Parts List

The service manual reveals that the SoundSpace 1 speakers are equipped with an active amplification system. The main unit divides the frequency range into high and low frequencies and feeds these to dedicated amplifiers in each speaker. This setup is designed to be energy-efficient and ensures optimal performance for each speaker component.

The Capacitors and Their Role

Upon closer inspection of the service manual, you'll notice the presence of capacitors within the CAT5 cable. These capacitors are part of a sophisticated circuit that goes beyond a simple crossover between the tweeter and woofer. The capacitors play a crucial role in filtering and amplifying signals, making direct connection to a standard audio input impractical.

Reverse Engineering for Custom Connection

Even if you were to attempt a manual connection, it would require an extensive reverse engineering process. Here are the key steps involved:

Determine the blend-point frequency: This is the point at which the high and low frequencies meet. Understanding this will help you properly calibrate your custom setup. Power split calculations: The woofer likely uses more power, so you'll need to determine the power split between the high and low frequencies. Identify rail voltages: Each amplifier will have specific rail voltages that must be replicated in your custom setup. Build power supplies and electronic crossover: These elements are necessary to replicate the functionality of the original SoundSpace 1 system.

Given the complexity of these steps, it is far simpler and more practical to address any issues with the SoundSpace 1 system itself. If the main unit is faulty, getting it repaired can restore the system's integrity, ensuring that the SoundSpace 1 speakers work as intended.

Alternative Solutions

If you are unable to repair the main unit, consider the following alternatives:

Replacing the main unit: In some cases, replacing the entire main unit might be the simplest solution. Using different speakers: If you need to connect speakers to a modern audio input, opt for conventional speakers designed for your application. The Nakamichi SoundSpace 1 speakers are not the right fit for every situation.

Conclusion

In summary, connecting Nakamichi SoundSpace 1 speakers to a modern audio input is not only complex but also impractical. The active amplification system integrated within each speaker makes a direct connection challenging. Instead, consider getting the main unit repaired if it is faulty or finding conventional speakers that suit your setup better.
