Parasound NewClassic 275v2 Two-Channel Power Amplifier - Black

Ninety Watts in One Rack Unit

The 275 v.2 is the one that disappears into a system. A 1U chassis, 17-1/4 inches wide and 2-1/2 high, weighing 20 pounds, making 90 watts per channel into 8 ohms and 150 into 4.

That shape is the point. It slides into a rack under other components, sits in a cabinet without a shelf of its own, or drives a second zone from a cupboard. It is a real Parasound amplifier in a space most amplifiers cannot occupy.

It keeps the load switch too. Set to the 2 to 3 ohm position it holds 150 watts per channel into a 2 ohm load, and bridged to mono it makes 200 watts into 8 ohms. Neither is a figure you expect from a chassis this slim.

Inside the Chassis

It is a fully discrete Class-AB design, not a compromise module dropped into a slim box. Signal-to-noise is 110dB A-weighted at rated output and 103dB unweighted, with response from 20Hz to 50kHz at −3dB.

Distortion measures 0.025% at average listening levels; the 0.35% figure applies only when the amplifier is driven to its full rated output, which in a domestic system almost never happens.

Input impedance is 33k ohms and sensitivity is 800mV for full rated output. Parasound covers it with a 2-year parts and labor warranty for the original purchaser from an authorized dealer.

Who Is This Amplifier Best For?

• Your rack has no room left — a 1U chassis 2-1/2 inches high and 20 pounds fits where a full-size amplifier cannot, so the system grows without new furniture.
• You are driving a second zone — 90 watts into 8 ohms is plenty for another room, and the amplifier can live out of sight in a cupboard or a closet rack.
• Your speakers are a hard load for their size — the load switch holds 150 watts per channel into 2 ohms, which is unusual in an amplifier this slim.
• You want the option of mono — bridged it makes 200 watts into 8 ohms, so a pair can biamp a main system or drive a demanding speaker properly.
• You are choosing the control stage yourself — the volume and the inputs belong to the preamp, and Halo P6 is the matched one

How Does It Connect to Your System?

Feed it from a preamplifier or processor by RCA and connect speakers to the binding posts. If the speakers dip toward 2 ohms, set the load switch before playing anything through it.

Turn-on can be manual, by 12V trigger with a looping output, or by audio-signal sensing, which is the useful one when the amplifier lives out of reach.

Pairs Well With

Here are some great companions:

• Preamplifier: Required, and the natural next decision — see our Preamplifiers.
• Speaker Cables: Carry the current properly — see our Speaker Cables.
• Interconnects: Balanced XLR is the better run from preamp to amp — see our Interconnect Cables.
• Audio Rack: Give a Class A/AB amplifier air around it — see our Audio Racks.

Frequently Asked Questions

How much power does it make?

90 watts per channel into 8 ohms and 150 into 4 ohms. With the load switch set to 2 to 3 ohms it holds 150 watts per channel into 2 ohms.

How much rack space does it need?

One rack unit. It is 17-1/4 inches wide, 16 deep and 2-1/2 high, weighing 20 pounds.

Can I bridge it to mono?

Yes. Bridged it makes 200 watts into 8 ohms, or 200 into 4 ohms with the load switch set.

What distortion should I expect in normal use?

0.025% at average listening levels. The 0.35% figure applies only at full rated output.

Is it a Class-D design?

It is fully discrete Class-AB, despite the slim chassis.

What warranty does it carry?

Parasound covers it with a 2-year parts and labor warranty for the original purchaser from an authorized dealer.
