Rupert Neve Designs RNDI
Rupert Neve is legendary in the professional audio game, renowned for his mixing consoles that have graced countless records. Many have strived to replicate the distinct sound these classic desks deliver. So, it's not too surprising that he has crafted one of the finest DI boxes available.
While the RNDI may not boast an exhaustive array of features like some of its counterparts, it excels in its main functions. Inside, you'll find custom-designed transformers by Rupert Neve himself and class-A biased, discrete FET amplifiers meticulously engineered to produce an exceptionally high headroom and harmonically rich audio. This makes it a perfect choice for capturing the nuances of basses, guitars, pianos and more.
When in speaker mode, the RNDI is capable of managing the intense output from a 1000-watt solid-state power amplifier (92 Vrms or 266Vp-p). This captures the instrument's complete sound, including the preamplifier, EQ, inserts, and the amp's output stages before they reach the speakers. By using this method, engineers can eliminate bleed in live settings and bypass any undesirable tonal alterations from the speaker cabinet or microphone.
FAQ: What's the Differences Between Passive and Active DI boxes?
Passive DI Boxes:
Passive DI boxes utilize a transformer to convert a signal and don't require any external power source to operate. This simplicity often makes them robust and durable, ideal for heavy-duty uses like touring. The transformer naturally provides galvanic isolation, which can help in reducing hum or ground loop issues. However, this transformer can introduce some coloration or character to the sound, which some users might appreciate for its warmth. Passive DI boxes are generally well-suited for high-level signals, like those from active pickups (or in the case of some DI boxes) amplifier outputs, since they can attenuate the signal without causing distortion.
Active DI Boxes:
Active DI boxes, on the other hand, use electronic circuitry for signal conversion and require an external power source such as batteries, phantom power, or an adapter. They typically offer a very high input impedance, making them ideal for instruments with high output impedance (lower signal levels, such as passive guitar pickups), ensuring that the instrument's tone is captured faithfully without high-frequency loss. These boxes are known for their clear, transparent sound, making them a preferred choice for those seeking an uncolored audio signal. However, their reliance on electronic components and external power might make them slightly more delicate compared to their passive counterparts.
In essence, the choice between passive and active DI boxes boils down to specific user needs and the nature of the source signal. While passive DIs are simple, robust, and can impart a warm tone, active DIs are versatile, transparent, and better suited for low-output instruments.
