San Francisco (1/9/12) -- Parasound has added a powerful new three-channel power amplifier to its premium Halo product family. The THX Ultra2 certified Parasound Halo A 31, which is rated at 250 RMS watts per channel, is sonically identical to the company's renowned five channel Halo A 51 and two channel Halo A 21 amplifiers.
The A 31 was developed for Parasound customers who want their surround systems to include uncompromised reproduction of stereo music. The A 31 is ideal for this because it also provides matched amplification for the center channel speaker.
Here are some of the practical applications for the A 31:
"It’s interesting how history repeats itself," said Parasound's president, Richard Schram. "In the earliest days of 5.1 home theater, we built two very popular three-channel amplifiers called the HCA-1203 and HCA-2003 that enabled people to repurpose their existing stereo systems for home theater surround sound. With today’s renewed interest in high end two channel the A 31 offers a uniquely practical way to get the best of both worlds.”
- Powering the C, LS, and RS channel speakers when a separate two-channel amplifier (or pair of monoblocks) is used for the L and R channel speakers.
- For L, C and R “one wall” theater systems without surround speakers.
- Powering the LS, RS and single back channel speaker in a 6.1 system.
The Parasound Halo A 31 provides high-bias Class A/AB operation with pure Class A operation up to 7 watts per channel. It easily delivers 250 watts per channel into 8 ohms and 400 watts into 4 ohms, all channels driven. Exceptional sound quality is maintained with XLR balanced inputs as a step-up alternative to the RCA single-ended inputs. Parasound's traditional Halo topology employs matched pairs of complementary JFETs for its input-pre-driver stages, matched pairs of complementary MOSFETs in its driver stages and 8 beta-matched 15 amp, 60 MHz bipolar output transistors for each channel.
The A 31 is direct coupled, and uses no capacitors or inductors in signal path with full power output down to 5 Hz. The loudspeakers are connected via heavy-duty 24k gold-plated five-way speaker terminals, and each is relay protected.
The power supply consists of a 1.35kVA encapsulated toroid power transformer with independent secondary windings for each channel. Power stability is maintained by four premium power-supply filter capacitors per channel totaling 94,000µF, and protected by DC servos and relay protection circuits.
The Parasound A 31 provides a gain control for each channel offering ±6db relative to THX reference level. This enables the A 31 to play louder in very large rooms and facilitates level matching with other amplifiers. Other features include: auto turn-on options by an audio signal with a threshold adjust or a 12v trigger with input and loop out jacks plus indicators for AC power, channel status, and high temperature. The heavy-duty 4u chassis has rear carry handles, and an included rack-mounting adaptor. The front panel is anodized aluminum.
The Parasound Halo A 31 will be available in April with a manufacturer's suggested retail price of $3,000.

Den veiledende prisen på $3000 er heller ikke avskrekkende.

Liker! Er dette noe nytt som kommer nå? Høres ut som en helt konge match til frontrekka (og den kommende frontrekka) mi

I følge teksten, så blir den tilgjengelig i løpet av april.
Dette er virkelig noe for meg.

Sjæl! Tror dere det tar lang tid før den kommer til Norge i forhold?
01-15-2012, 17:41 #6
oi. Denne saken var interessant. Et direkte konkurrent til XPA-3

Noen som tør å tippe på pris i Norge for denne ? Et sted mellom 25.000 og 30.000 ? Ser for meg at dette kan bli en perfekt match til frontrekka mi med Mentor 6 og Mentor Vokal..:-)

Emotiva er gode forsterkere til en rimelig penge, men det får da være grenser for hva de sammenlignes med.

Noen som har fått testet denne enda??

Spent på å høre inntrykkene av denne lille saken selv
