Balanced Audio Technology (BAT) has announced the release of its latest offerings in high-fidelity audio equipment – the BAT VK-85 Preamplifier and REX 300 Power Amplifier. These new additions to BAT's product lineup promise to deliver top-notch sound quality through innovative design and advanced technology.

The REX 300 Power Amplifier, a sibling to the highly acclaimed REX 500, boasts a robust 200W per channel output while incorporating cutting-edge circuitry and power supply technologies. Featuring BAT's TWIN-Path split power supply topology and SuperPak Quattro capacitor bank, the REX 300 ensures optimal current delivery and exceptional power-supply filtration. 

Notably, the amplifier circuit's simplicity, with just two gain blocks and an output stage based entirely on "N channel" MOSFET devices, contributes to its high performance and sonic accuracy.

BAT has also introduced an Intelligent Power Upgrade option for the REX 300, allowing users to convert the stereo amplifier into a monoblock configuration seamlessly. This upgrade path enhances the amplifier's current delivery, resulting in even better sonic performance and effortless sound reproduction.

BAT REX-300 Power Amplifier Main Features:

  • BAT’s new fourth-generation SuperPak topology which provides four levels of power-supply filtration
  • Uses the same split power supply topology TWIN-Path found in the larger REX 500
  • Fuse-less protection circuit for enhanced sound and user-friendly operation
  • There are only two gain stages with Zero Global Feedback and the circuit is fully balanced from input to output
  • Amplifier circuit is based entirely on N-Channel MOSFET devices
  • The REX 300 can be ordered as either a stereo amplifier or as a monoblock
  • Power output in stereo configuration: 200W/ch at 8 ohms and 400W/ch at 4 ohms
  • Frequency Response: 3Hz to 200kHz / Nominal Gain into 8Ω: 25dB
  • Dimensions w x h x d: 19" x 6.5" x 18" / Weight: 70 lbs

Complementing the REX 300, the BAT VK-85 Preamplifier embodies BAT's dedication to audio excellence with a host of refined circuit technologies. The SuperPak Quattro and Second Generation Transformer Coupled Outputs significantly reduce noise and distortion, while the Unistage Design ensures the integrity of the input signal by employing a single gain stage without global feedback.

Similar to its power amplifier counterpart, the BAT VK-85 utilizes High-Current N-Channel MOSFET devices and a proprietary shunt volume attenuator for precise volume control. The preamplifier's fully balanced circuitry further enhances signal integrity, contributing to its musicality, midrange clarity, and dynamic range.

According to BAT, the decision to employ fully balanced circuits stems from their belief that balanced topology provides a more complete signal representation, resulting in superior audio performance. Additionally, the VK-85 offers a mix of balanced and single-ended inputs and outputs for enhanced connectivity and compatibility with various source components.

BAT VK-85 Preamplifier Main Features:

  • Fully balanced design circuit topology
  • Revised power supply incorporates BAT’s new fourth-generation SuperPak topology
  • Second-Generation Transformer-Coupled Outputs
  • Unistage Design with a single gain stage
  • High-Current N-Channel MOSFET Circuit
  • Noise unweighted: -96dB / THD at 2V output: 0.01%
  • Inputs: 3 XLRs and 2 RCAs / Outputs: Main 2 XLRs and Tape Out 1 RCA
  • Proprietary electronic shunt volume attenuator with 140 steps of 0.5dB resolution
  • Frequency Response: 2Hz to 200kHz / Maximum Gain: 20dB
  • Dimensions w x h x d: 19" x 5.75" x 15.5" / Weight: 40 lbs

Both the BAT VK-85 Preamplifier and REX 300 Power Amplifier are set to hit the market in the second quarter of 2024, with suggested retail prices of $12,500.00 and $15,000.00, respectively. Audiophiles eager to experience these new offerings firsthand can visit BAT's exhibit at AXPONA 2024 in Suite 348 from April 12 to 14.
