The Red Wine Audio Signature 70.2 monoblock amplifiers were created for music connoisseurs seeking a sublime listening experience, dependability, and value.

Carefully designed to deliver a well-balanced musical presentation and long-term listening pleasure, the Signature 70.2 monoblock amplifiers combine the finest sonic attributes of classic tube amplification (midrange warmth, rich tonal character, and smooth high-frequency resolution) and solid-state amplification (rock-solid bass response, realistic dynamic range and clarity) to enhance the listener’s emotional involvement with the music.

As with all Red Wine Audio products, the Signature 70.2 monoblock amplifiers are powered by clean, high-current sealed lead-acid (SLA) batteries that allow all the nuances of the music to emerge with remarkable coherence and integrity. By running on internal SLA battery power and isolating itself from the AC power grid, each Signature 70.2 monoblock amplifier is free from the entire AC to DC conversion process and the associated electrical noise problems that hinder the performance of conventional AC-powered amplifiers.

On the inside of each Signature 70.2 monoblock amplifier is a unique circuit design that demonstrates our beliefs in using premium parts, shorter signal paths, and SLA battery power. On the outside you will enjoy elegant aesthetics and superb build quality. Every pair of Signature 70.2 monoblock amplifiers are proudly hand-made in the USA and carefully tested, inspected, and packaged before making its journey to our highly-valued and satisfied customers.

Divide and Conquer...

Each Signature 70.2 Monoblock Amplifier contains a modified version of the Signature 30.2 circuit -- configuring the output stage to operate in “paralleled output mode,?which offers 2x the maximum output current drive capability. Monoblock operation also boasts complete separation of the left and right channels. Each channel is now powered by its own dedicated, high-current SLA battery supply.

Compared to the Signature 30.2 stereo amplifier, the Signature 70.2 monoblock amplifiers feature improved bass response, sound staging, stereo imaging, and spaciousness. This distinctiveness is attributed to the monoblock operation?the separate power supplies, complete isolation between the channels, and the change in the output stage circuit configuration (paralleled output mode).

SMART module equipped

The Signature 70.2 monoblock amplifiers feature a Red Wine Audio innovation?the SMART module (SLA battery Monitoring and Auto Recharge circuiT). This is a custom-designed circuit board that continuously monitors the voltage of the internal SLA batteries. If the voltage drops too low, the SMART module automatically turns off the Signature 70.2 and begins the battery recharge process for you.

With the SMART module, any user concern of accidentally damaging the internal SLA batteries by forgetting to turn off the Signature 70.2 is eliminated!
 

Like finely-tuned musical instruments?

The Signature 70.2 monoblock amplifiers are a highly refined and improved version of our award winning Signature 70 monoblock amplifier.

Listed below are the major refinements in its musical presentation:

a) A warmer, and more seductive sound signature
b) Greater dimensionality
c) Added bass weight
d) Sweeter top end
e) Richer tone, without sacrificing any pace, rhythm and timing

The amplifier board in each Signature 70.2 has been heavily modified in order to achieve the sonic enhancements listed above. Below are examples of such refinements:

1) A new output filter stage design that features all new, higher-quality components as well as all new filtering characteristics.
2) The new output filter components are now hard-wired together (point-to-point) and have the speaker output wiring directly connected to them to offer an even shorter, cleaner signal path.
3) A higher grade of PIO (paper-in-oil) input capacitor
4) Modified input stage design, which also features higher quality parts such as resistors, dc offset pot, etc.

Also featuring:

• Custom “touch-sensing?power on/off switch with built-in LED that emits a soft, red glow. This switch is mounted flush with the black-anodized aluminum front panel for a clean appearance and is also made of smooth, black-anodized aluminum.

• Black, powder-coated aluminum enclosure with a smooth, 0.5?thick black-anodized faceplate that is laser-etched.

• Premium input and output jacks by Vampire

• Rapid-speed SLA battery charger with universal input voltage (100 ?240Vac, 50/60Hz) and IEC power input jack, and output cable featuring a heavy-duty XLR plug
