With a weight of 100 lbs. and a chassis depth of 21.5“(54.6 cm), two rear handles were added to make it easier to lift and move. Larger 120mm, low profile fans are built into the bottom cover plate horizontally to provide ventilation.
The REF160S distills the astonishing resolution, dynamic impact, musical purity and finesse of the 160M into one beautiful and attainable chassis. It was designed for the music lover in all of us.
Technical Specifications
POWER OUTPUT: 140 watts continuous from 20Hz to 20kHz. 1kHz total harmonic distortion typically 1% at 140 watts, below 0.04% at 1 watt. (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 critical).
POWER BANDWIDTH: (-3dB Points) 5Hz to 70kHz.
FREQUENCY RESPONSE: (-3dB points at 1 watt) 0.5Hz to 110kHz.
INPUT SENSITIVITY: 2.4V RMS Balanced for rated output. (25.5 dB gain into 8 ohms).
INPUT: 300k ohms Balanced; 100k ohms Single-ended.
OUTPUT POLARITY: Non-inverting. Balanced input pin 2+ (IEC-268).
OUTPUT TAPS: 16 ohms, 8 ohms, 4 ohms.
OUTPUT REGULATION: Approximately 0.6dB 16 OHM LOAD TO OPEN CIRCUIT (Damping factor approximately 14).
OVERALL NEGATIVE FEEDBACK: 14dB SLEW RATE: 13 volts/microsecond RISE TIME: 2.0 microseconds.
POWER REQUIREMENTS: 105-130VAC 60Hz (210-250VAC 50Hz) 875 watts at rated output, 700 watts in Triode mode, 500 watts at “idle”, 3.6 watts off
TUBES REQUIRED: 4 matched pair KT150 (Power output V1-4); 4 6H30 (Gain stage V5 and V6).
DIMENSIONS: Width 19.0” (48.26 cm) Height 10.25” (26 cm) Depth 21.5” (54,61 cm)
With Handles and Connectors: 24” (60.96 cm)
