Overview
Sonically the Reference 210 is simply stunning in every respect. Resolution of detail is uncanny, with a vivid, transparent, you-are-there quality that is captivating. The performers are not mere images, but have real body, weight and presence. The soundstage is unbounded, with palpable space and air. Fine dynamic shadings and crescendos alike are unrestrained. And, bass impact, speed and articulation are a revelation. Once you have heard them, you will not soon forget the magic of these amplifiers.
Specification
| POWER OUTPUT: 210 watts per channel continuous from 20Hz to 20kHz. 1kHz total harmonic distortion typically 0.5% at 210 watts, below .02% at 1 watt. |
| Approximate actual power available at "clipping" 240 watts (1kHz). (Note that actual power output is dependent upon both line voltage and "condition" i.e.: if power line has high distortion, maximum power will be affected adversely, although from a listening standpoint this is not very critical.) |
| FREQUENCY RESPONSE: |
| (-3dB points at 1 watt) 0.5Hz to 240 kHz. |
| INPUT SENSITIVITY: 1.7V RMS Balanced for rated output. (27 dB gain into 8 ohms.) |
| INPUT IMPEDANCE: 200K ohms Balanced |
| OUTPUT TAPS: 4, 8, 16 ohms. |
| OUTPUT REGULATION: Approximately 0.6dB 16 ohm load to open circuit (Damping factor approximately 14). |
| HUM & NOISE: Less than 0.3mV RMS -106dB below rated output (IHF-A weighted, input shorted, 16 ohm output). |
| POWER SUPPLY ENERGY STORAGE: Approximately 787 joules. |
| POWER REQUIREMENTS: 105-130VAC 60Hz (260-250VAC 50Hz) 680 watts at rated output, 950 watts maximum, 380 watts at "idle," .15 watts off. |
| TUBES REQUIRED: |
| 3 - Matched pair 6550C (Power output V1-6); 1 - Matched pair 6550C (Driver V8-9); 2 - 6N1P (Gain stage V7 and Regulator Driver V10); 1 - 6550C (Regulator V11). |
| DIMENSIONS: 19" (48.3 cm) W x 8.75" (22.2 cm) H x 19.5" (49.5 cm) D. Handles extend 1.5" (3.8 cm) forward. |
