Class A+D Stereo Amplifier Brigeable into a 160 watt Mono Amplifier

With 2 X 90W Class A+D stereo amp, bridgeable into a 160W mono amp, STA-6 is designed with enhanced even-order harmonic circuitry that produces sonic characteristic similar to NuPrime STA-9, but leaning toward neutral with a slight hint of warmth. The STA-6’s spacious, transparent, dynamic and luxuriously textured soundstage has to be heard to believed.

NuPrime audiophile quality commercial products are typically not sold in retail stores. The commercial product line is not designed for style but performance can be sound quality can be just as good as the home product line.
The STA-6 amplifier is derived from the Single End Class A Module + Class D design first introduced in the STA-9. By joining a powerful high impedance singled ended amplifier circuit in the preamp stage with a well integrated Class-D power stage, the STA-6 offers the richness of Class A sound with the remarkable speed and clarity of NuPrime Class-D design. Audio enthusiasts are bound to be impressed.
The NuPrime amp circuit improves on traditional Class-D design by using a self-oscillating circuit to generate pulse-width modulation. The amplifier switches at a frequency of 500kHz, well beyond the compact disc’s 44.1kHz sampling rate. Most class-D amps switch at 300kHz or lower. A new low noise switching power supply is designed specifically to complement the STA-6 amplifier. The overall result is unprecedented transient speed, smooth with lots of details and an almost shocking level of dynamic impact.The STA-6’s frequency response to 50 kHz elevates vocals into emotional experiences; similarly, instrumental upper registers mimic a live performance’s shimmering heights.The STA-6 is designated for NuPrime Commercial product line and it is designed to be highly reliable under no-load condition and enhanced short circuit protection.

Can the amplifier’s speaker terminals be used as source inputs (e.g. to REL Subwoofer) ?

In some applications, the speaker outputs from the power amplifier are used as source signals for devices such as REL sub woofer. For such application, usually the receiving devices should have DC offset blocking capability because some amplifier by design has floating ground (DC offset) on the speaker outputs.

The following models have no DC offset on the amplifier speaker outputs and the negative terminal is also the ground:
NuPrime STA-9, MCH-K38, IDA-6, IDA-16, STA-9X, AMG STA

The following models’ speaker outputs can not be connected directly to sub woofer input:
NuPrime Reference 20, ST-10, IDA-8, ST-10M, Evolution One, Evolution Two, Evolution STA, AMG One, MCX-1,2,3,4

REL has provided instructions for connecting Class-D amp with floating speaker outputs to their sub woofers, please contact REL. All currently shipping REL sub woofers can be connected directly to any Nuprime amps.

What kind of trigger cable can be used for your products?

When a device has a 12V trigger input, it is designed to be turned on when a 12V is detected. You can use any standard male to male 3.5mm (3-pin type) cable.
https://components101.com/connectors/35mm-audio-jack

The Tip section is +12V, the bottom Sleeve section is GND, and the middle Ring section is not used. Nuprime’s trigger design uses 3.5mm stereo cable pin 1 and pin 3. A mono trigger cable shorts pin 2 and pin 3, it can be used to connect the Nuprime device to another device’s trigger that only uses a mono cable.
