![]() The effects of poor speaker connections can easily be measured when testing the AHB2 power amplifier. The Benchmark AHB2 power amplifier is so clean that poor speaker connections can easily create more distortion than the entire power amplifier. Spring-type (non-locking) banana plugs almost always provide poor connections and should be avoided. ![]() In contrast, spade lugs and pins often provide poor connections. Of the more traditional speaker connectors, we have found that locking banana plugs provide the next best connections. The SpeakON™ connectors provide a reliable low-impedance connection that can withstand high-currents. In our lab tests we have found that heavy-duty 40-amp SpeakON™ connectors consistently outperform spade lugs, pins, and banana plugs. Use this 2-pole cable for stereo and bridged mono applications. The NL4 jacks provide two additional contacts (+2 and -2) but these extra contacts are only needed for some bi-amp applications. It is compatible with the four-conductor NL4 jacks on the back of the AHB2 power amplifier. ![]() The plug used on this cable is a two conductor Neutrik NL2 SpeakON™ connector. The -1 pin connects to the black locking banana plug. The +1 pin connects to the red locking banana plug. These 2-pole cables connect to the +1 and -1 pins in an NL2 or NL4 jack. This Cable is Compatible with NL2 and NL4 Jacks Hand assembled in the USA with true silver solderīenchmark Studio&Stage™ Speaker Cables combine the best cable, connectors, and construction techniques in order to offer performance that meets the demands of world-class studios, while providing the strength and reliability required for stage applications. Price is for one cable, Order 2 for a stereo pair. In contrast, the revolutionary AHB2 was specifically designed to deliver true high-resolution performance.ĭ/A conversion technology has outpaced the development of new power amplifiers.BENCHMARK STUDIO&STAGE™ SPEAKER CABLE - NL2 (or NL4) TO LOCKING BANANA CABLES ARE SOLD INDIVIDUALLY Most power amplifiers are well matched to the limitations of the CD format, but they fall well short of the capabilities of high-resolution formats. Power amplifiers are a weak link in most audio systems. The musical details and emotion captured on today's finest High-Resolution-Audio recordings can only be fully appreciated when every component in the signal chain is capable of true high-resolution performance. With the AHB2, you will discover previously overlooked nuances, dynamics, and detail in your favorite recordings and experience the full potential of the latest high-resolution 24-bit PCM and 1-bit DSD audio formats. The frequency response of the AHB2 extends beyond 200 kHz. The dynamic range of the AHB2 is 132 dB, making it 10 to 30 dB quieter than some of the very best reference-quality power amplifiers. The AHB2 power amplifier delivers musical details without introducing the masking effects of amplifier noise and distortion. The Benchmark AHB2 is the ideal match to the performance limits of High-Resolution-Audio (HRA) formats.
