Solid-state preamplifier. The 202 is a two-chassis design; the power supply, with its quad-rectified 170VA toroidal transformer and 39,600µF of filter capacitance, is housed in its own shielded chassis. The signal path is a zero-feedback, high-bandwidth, 1.5MHz open loop in a balanced Krell Current Mode design, terminating in Krell CAST (Current Audio Signal Transmission). Frequency responses: 20Hz–20kHz, ±0.02dB; 0.01Hz–1.5MHz, +0/–3dB. THD: <0.004%, 20Hz–20kHz at 4V or 4mA RMS. Signal/noise: >100dB wideband, unweighted; >109dB A-weighted (both at 4V or 4mA RMS). Input impedance: 45 ohms CAST (current mode operation), 95k ohms balanced, 47.5k ohms single-ended. Output impedance: >1M ohm CAST, 50 ohms balanced, 25 ohms single-ended. Gain: 12dB CAST or balanced, 6dB single-ended. Analog Inputs: (2) CAST (LEMO), (2) balanced (XLR), (3) single-ended (RCA), (1) tape loop (RCA). Analog Outputs: (2) CAST, (1) balanced, (1) single-ended and (1) tape. |
