Legendary tone, unquestionable reliability. Eight channels of the superb-sounding RNDI in one rack space.
With over 25,000 channels shipped since its launch in 2015, the RNDI is firmly established as the direct interface of choice for many of the worlds most discerning musicians and engineers. Its custom transformers and discrete FET amplifiers deliver a vibrancy and clarity that captures the full harmonic depth of any source, and its unquestionable reliability has led to its adoption by thousands of touring artists. The RNDI-8 puts eight channels of this beloved circuit into a single rack space, making it the ideal solution for high-end stage rigs, studios, and synth enthusiasts. With the RNDI-8, stunning direct sound doesnt require extra work its just there.
The RNDI-8 consists of eight independent channels of RNDI Active Transformer Direct Interface in a single rack space, providing instrument direct injection for electric guitar & bass, synthesizer, keyboard, piezo pickup, or any other instrument-level source. The discrete, class-A circuit topology is built around Mr. Rupert Neves custom transformers, resulting in outstanding sonic performance and supremely natural sound from 5Hz all the way out to well beyond 90kHz. Each channel can handle input levels up to +21dBu (+31dBu with the pad engaged), the low impedance transformer-coupled output drives long lines with minimal loss, and the rugged chassis steel construction is designed for a lifetime of stage and studio use.
Transformer + Discrete FET: The Best of Both Worlds
The RNDI-8s signature sound stems from the custom-designed transformers and class-A, discrete FET input amplifiers. The carefully designed union of these two elements is key to the RNDI-8s unique accuracy, tone, and response.
The Eight Custom Transformers
The RNDI-8s custom-wound output transformers provide isolation while adding musical harmonics and dimension to the sound. The low impedance, transformer-balanced outputs excel at driving long cable runs, and the performance is consistent regardless of the connected equipment. This is important for both live and studio environments where the unamplified signal may travel 100ft or more before hitting an amplifier.
The Class-A, Discrete FET Input Amplifiers
The class-A & discrete FET input amplifiers in the RNDI-8 are powered by 48V phantom and create a high impedance input of over 2M Ohms, ensuring consistent performance with a wide variety of instruments. The class-A design eliminates crossover distortion that can otherwise be added to the signal and introduce unwanted upper-order odd harmonics. With the RNDI-8, the harmonic content is derived from the octave (2nd order) and fifth above octave (3rd order) relative to the fundamental. These musically relevant harmonics, present in subtle amounts, enhance the richness of the original signal and provide a distinctly musical response. Furthermore, the discrete aspect of the RNDI-8s design means there are no ICs or digital components to potentially cause negative effects on the tone.
Giant Headroom, Wide Bandwidth
The RNDI-8 has a uniquely wide bandwidth with a frequency response stretching from 5Hz all the way past 90kHz. However, measurements are only part of the equation: couple this extended bandwidth with the output transformers harmonic enhancement and an absolutely thunderous low-end emerges, adding an unparalleled feeling of depth. All this happens without compromising any of the midrange richness or top-end sparkle that defines your instrument.
Maximum input level is a massive +21dBu, making the RNDI-8 capable of handling not only instruments but also professional line-level sources like interfaces and drum machines. And with the addition of a -10dB pad, that number soars to +31dBu more than enough for even the highest-output DJ mixers. This makes the RNDI-8 incredibly versatile, enhancing the sound of nearly any connected instrument or source.
Two Distinct Ground Lift Options
Most direct interfaces include a ground lift switch at the output, and the RNDI-8 includes this standard DI lifting option via eight individual Pin 1 Isolate switches on the rear panel. Engaging this button will usually eliminate common sources of hum in the signal path. However, the RNDI-8 also includes eight ground lift buttons on the front panel which separate each channels circuit ground from the chassis ground, providing another helpful option to detect and eliminate unwanted ground hum.

Protect your investment with the Long & McQuade Performance Warranty
A warranty can be a very important factor when making a buying decision. Because repairs can be very expensive in terms of parts and labour costs, manufacturers usually only provide one year limited warranties that generally only cover items that malfunction due to a manufacturer’s defect. With an important purchase such as a musical
instrument or piece of studio gear, however, many people want to have the peace of mind in knowing that their investment will be protected should the product no longer be performing at 100%.
Because of this, Long & McQuade provides our customers with a FREE one-year Performance Warranty on most of our products. The Long & McQuade Performance Warranty supplements the manufacturer’s warranty to ensure that our customers receive complete “no hassle” warranty coverage within their first year.
How does the Long & McQuade Performance Warranty differ from most manufacturers' warranties?
- Performance Guarantee: Normal wear and tear is covered, so your product will be performing as well as the day you purchased it for the entire duration of the coverage. Band and Orchestral Performance Warranty does not include replacing pads or cleaning for woodwind instruments, unless deemed necessary by our repair staff. Ultrasonic cleaning for brass instruments will be provided if deemed necessary by our repair staff, but is not routinely offered under the Performance Warranty.
- Product Replacement: If your product cannot be fixed or costs too much to fix, we will replace it with the equivalent model for no additional charge. If this is not possible, a full refund will be provided.
- No Lemon Policy: Your product will be replaced should the same problem occur multiple times.
- Convenient: Easy drop off and pick up of the product at any Long & McQuade location.
- Guitar Setup: Guitars purchased at Long & McQuade come with 1 free setup, to be redeemed within 1 year for new guitars and 90 days for used guitars.
- Loaners Available: A loaner product may be given while the product is being repaired.
- Power Surge Protection: Your product is covered even if damaged from a power surge.
- Accessory Coverage: Any peripheral devices or accessories that come with your product (i.e. foot pedal, case) are also covered.
- Commercial Use Coverage: Music and recording professionals who purchase gear for “heavy-use” commercial purposes will still be covered.
Long & McQuade reserves the right to restrict the purchase of additional years of Performance Warranty. Used products come with a 3-month Long & McQuade Performance Warranty. Some products (i.e. computers, software, cymbals and other items) are covered only by the manufacturer‘s warranty. Consumables (i.e. strings, reeds, drum sticks, batteries, tubes, cross faders) are excluded as they are designed to be replaced. Cosmetic Damage, Accidental Damage, or problems caused by Humidity or Temperature Issues are not covered. Speakers damaged by overpowering are generally not covered. Our coverage does not provide compensation for loss of use. As of June 2018 the Performance Warranty is no longer transferable. The warranty is only valid in Canada.
Purchasing additional years of coverage
Some manufacturers provide warranties for longer than 1 year; however, these are usually limited warranties that do not provide the same coverage as the Long & McQuade Performance Warranty. Customers interested in more complete and convenient (but not necessarily longer) coverage are still able to purchase additional years of the Performance Warranty.
If you are interested in receiving this coverage for longer than one year, you have the option of purchasing additional years of the Performance Warranty. The pricing is as follows:
- NEW products: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year.
- USED products: 4% of the current new selling price to increase the warranty from 3 months to 1 year. 4% for each additional year.
- GUITARS: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year. $45 maximum. An additional free setup is not included with additional purchased years of Performance Warranty.
- BAND and ORCHESTRAL instruments: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year.
