The REX replaces the company's VK-75SE/VK-150SE models and like other BAT products, the amp employs customized oil-filled capacitors in important areas of the power supply, and unique to this product, the company eliminated the typical power supply rail fuses from the signal path. BAT says the elimination of these wires along with multiple fuseholders that are associated with the rail fuses improves signal clarity. To further protect signal clarity, the amp also utilizes protection circuits that eliminate the fuses that most amps use to protect tubes, and with the combination of the amp's auto-bias circuit, dealers and clients don't need to use meters to adjust tube bias.
Using a zero-feedback , triode, fully symmetrical design approach in combination with 6C33C-B tubes in the output stage, the monoblock REX is rated to deliver 160 watts of power and the stereo version of the amp is rated to deliver 80 watts per channel.

The Integra DTA-70.1 is designed as a companion product to the Integra DHC-80.1 9.2-channel A/V processor for theater systems that use the new "height" or "stereo-wide" channels. The amplifier is also a companion to seven-channel preamps such as the Integra DHC-40.1 with the extra channels dedicated to additional zones or for bi-amplified connections that double the power available to the main stereo loudspeakers.
The DTA-70.1 is an 11.7-amp power supply with professional-style balance line inputs. Each channel has identical symmetric circuit layouts, configured in a push-pull topology utilizing three-stage inverted Darlington circuitry and output transistors. It uses the company's WRAT (wide range amplifier technology) with low negative feedback, closed ground-loop circuits, and HICC (high instantaneous-current capability) to achieve an extended frequency range, low noise, and high dynamics, according to the company.
The power bandwidth is 5 Hz to 100 kHz, +/-3dB, and the IHF A-weighted signal to noise ratio is an excellent 110 dB.
There are gold-plated XLR and machined solid brass RCA inputs for each channel. The color-coded speaker outputs use gold-plated banana-plug-compatible transparent binding posts. It has a 12-volt trigger input for remote turn on and off capabilities, and an automatic power-down capability.
The Integra DTA-70.1 power amplifier is now available with a suggested retail price of $1,800.

A good loudspeaker is designed to deliver sound with little distortion and coloration. But when even great speakers are placed in a room, things change. Walls, furniture, and other objects reflect and absorb the sound from your speakers, creating complex distortions specific to your room, which could not have been predicted by the loudspeaker designer.
Advanced Room Correction
Audyssey MultEQ® XT is a room equalization solution that calibrates any audio system so that it can achieve optimum performance for every listener in a large listening area. MultEQ XT captures acoustical information at multiple locations throughout a listening area in both the time and frequency domains. It uses a sophisticated clustering algorithm to combine this information so that acoustical problems are accurately analyzed. Based on these measurements, MultEQ XT calculates an equalization solution that corrects for both time and frequency response problems in the listening area and also performs a fully automated surround system setup. The result is clear, well-balanced sound for every listener. Wisdom Audio licensed the most sophisticated form of this technology for use in our systems, and worked closely with Audyssey™ to ensure that you get all the performance you deserve.
Multiple Setup Memories
We then went further and provided support for recalling up to three complete and independent setup calibrations, any of which can be selected as needed. While a single setup is all that is necessary, having the ability to recall any of multiple setups can solve some otherwise difficult situations. For example, you might want to have selectable setups for:
Different room conditions (e.g., drapes open vs. closed)
Slightly different target curves (e.g., music vs. gaming)
Various seating arrangements (e.g., solo listening vs. the whole family)
Bi- or Tri-amplification
People who have wanted to extract the highest performance from their systems have known for a long time that driving each section of the speaker directly and separately yields the finest results. Of course, this requires having a dedicated, active crossover to divide the frequency range appropriately before the power amplifiers, so that they can then drive the speakers directly.
Biamplification makes use of two channels of amplification to drive different portions of a single channel. The most common instance of “bi-amping” today is in home theater applications, wherein a dedicated subwoofer handles the deepest bass, while the remaining audible range is handled by the various front and surround speakers. But you can also biamplify a full range loudspeaker, driving the woofer separately from the drivers that handle the midrange and treble frequencies.
Logically, you can combine these two approaches, and the result is “triamplification.” A “tri-amped” system uses separate amplification for three audible ranges. In our case, the three ranges are:
Deepest bass (one or more subwoofers)
Mid-bass (the woofers in the front and surround speakers)
Midrange and treble (the planar magnetic panels)
Since each channel of the amplifier is delivering current into its load only over a limited range of frequencies, several forms of distortion are reduced as compared to each channel handling the full range of musical information.
The SC-1 supports up to a “7.3 channel” system, meaning that up to seven main speakers can be supported (all of which are biamplified), plus up to three independent subwoofer channels. All of these outputs benefit from room correction, described above.
System-Specific EQ
Wisdom Audio speakers deliver extraordinary performance from slim, elegant enclosures. However, we cannot cheat the rules of physics. Delivering powerful bass from such small enclosures places unusual demands on both the woofers and the amplifiers used to drive them.
Specifically, equalization is used to compensate for the unusually small enclosure volume behind the woofer. This approach is used in almost all dedicated subwoofers today, and we use it in our full range speakers. Doing so allows us to achieve the bass performance usually associated much larger speakers, but in elegant enclosures that support modern lifestyle choices.
