*SILVER FINISH MODELS ARE SPECIAL ORDERS - CALL FOR DETAILS*

Product Description

The TEAC AX-505 Stereo Integrated Amplifier is a compact, high-performance amplifier designed for audiophiles seeking dynamic, precise sound in a space-efficient package. Powered by a TEAC-tuned Hypex Ncore module, it delivers 130 watts per channel (8 ohms, 1 kHz) or 200 watts per channel (4 ohms, 1 kHz), driving a wide range of speakers with exceptional clarity. Featuring balanced XLR inputs, a discrete phono stage for MM cartridges, and a CCLC (Coupling Capacitor-Less Circuit) headphone amplifier, it ensures low-noise, high-fidelity audio. The ladder-resistor volume control and MUSE op-amps enhance sound quality, while the robust aluminum chassis with patent-pending ‘Pin-Point’ feet minimizes vibrations. With analog VU meters and a sleek black finish, the AX-505B blends vintage aesthetics with modern engineering, reflecting TEAC’s legacy of audio excellence since 1953.

Key Features  

• TEAC-Tuned Hypex Ncore: Delivers 130 watts x 2 channels (8 ohms, 1 kHz, 1% THD) or 200 watts x 2 channels (4 ohms, 1 kHz, 1% THD), tuned for maximum musical expression across genres.
  
• Balanced Input Capability: One pair of XLR balanced and three RCA unbalanced inputs minimize external noise, ensuring clean signal transmission for high-fidelity playback.
  
• Discrete Phono Stage: Supports MM cartridges with a dedicated RCA input and ground terminal, delivering rich, detailed vinyl playback.  
  
• CCLC Headphone Amplifier: Coupling Capacitor-Less Circuit design provides 500 mW + 500 mW (32 ohms) with excellent channel separation for balanced and single-ended headphones (16–600 ohms).
  
• Ladder-Resistor Volume Control: Precision volume adjustments with high-grade MUSE op-amps ensure uncolored sound and superior audio quality.
  
• Vibration Control: Patent-pending ‘Pin-Point’ feet (Japan Patent Nos. 4075477, 3778108) with a three-point spiked design reduce resonance, enhancing clarity and bass response. 
  
• Analog VU Meters: Illuminated meters with four-step dimmer (bright, mid, dim, off) offer a nostalgic, real-time visual of output levels.  
  
• Fanless Cooling: Passive cooling eliminates fan noise, ensuring a quiet listening environment and reliable performance.  
  
• Versatile Connectivity: Includes 1 XLR, 3 RCA (including phono), and gold-plated binding posts for secure speaker connections, plus a 3.5mm trigger input for power syncing.
