Naim Amp to REL Subwoofer Cable. High-Level Input Lead

A REL approved cable designed to offer the ‘Bassline Blue’ experience using alternative cable and connectors. We worked with REL in the creation of this cable to ensure that the in-built circuitry performed to the same strict tolerances required to interconnect Naim amplifiers with REL subwoofers.

*Please note this is not the official 'Bassline Blue' cable, this is a replica product.

Why the ‘Bassline Blue’ experience?

“What’s In a NAIM? These same benefits are available to most NAIM owners—especially the older, classic models. These units feature an unusual output impedance that is quite complex. REL worked closely with NAIM engineers to model this behaviour and arrived at a special circuit built into each NAIM cable that replicates this impedance so that it is safe to run Bassline Blue on early NAIMs. We even sourced a wonderful stackable banana plug that makes it so easy to use the cables, just plug them in to NAIM’s flush-mounted chassis banana sockets and then plug your speaker cables directly into the rear of our stackable banana plug”

• Van Damme 2.5mm Ultra-pure oxygen free copper for outstanding sonic integrity
• Neutrik twist lock Speakon connector
• Stackable banana plugs; Black, Red, Yellow
• Labelled for ease of use
• Cables 2m or more supplied with a Velcro™ cable tie
• Terminated with a 3.5% Silver Solder

**Please note these cables can be used in all REL setups, not just with Naim amplifiers.

Connecting your REL to the amplifier

The standard high level hook up procedure is: attach the red wire to the amplifier’s right positive speaker output terminal; attach the yellow wire to the amplifier’s left positive speaker output terminal; attach the black wire to which ever of the amplifier’s ground output terminals is convenient; plug the Speakon connector into the sub’s high level input.

For differential amplifiers using one sub, simply use the standard connecting scheme with the exception of connecting ground to chassis ground, not to speaker output ground, and then connecting into the high level input (Hi Input or Unbal Hi Input on Stentor III and Studio III).

For differential amplifiers using two subs for each channel: connect red to positive; yellow to negative; and black to chassis ground; plug the Speakon into the balanced high level input (Bal Hi Input). Low-level connection, RCA inputs (or XLR on some models), is always an option, should high-level connection not be possible, or in a theatre system where both high-level and low-level connection should be used. When connecting to the low level inputs, connect a single RCA cable to the 0dB RCA jack. Additional gain can be achieved by connecting to the +12dB input. If you are connecting two channels of stereo output from a pre-amplifier, simply use a high-quality y-adaptor to sum the two signals together.

Positioning

The optimal position for a REL is in one of the corners behind the main speakers. This position provides 9 dB of mechanical amplification and allows for the most linear true low bass wave launch, owing to the ability to tune the sub to the axial node of the room, or longest throw distance.
