Description
ATTENTION! This auction is for AUDIO RESEARCH PREAMPLIFIER SP 14 ONLY!!!!! If you want to by extra AUDIO RESEARCH CLASSIC 60 - See My other auctions. The SP14s musicality comes surprisingly close to the state of the art, with soundstage of remarkable depth and breadth; imaging of uncanny solidity: palpable dynamic authority; timbral accuracy that virtually recreates live music; an exceptionally low noise floor; and a special ease with frequency extremes. But unlike many high-performance preamplifiers, the SP14 doesnt scrimp on control features. It has separate Gain and Attenuation for wide-ranging-yet-subtle level management. Separate Input and Record Output selectors (with a common menu) permit exceptional flexibility in playing and recording: owners can listen to one source while recording from another. The Bypass switch allows owners to remove the Balance and Mode controls from the signal path, for greater sonic purity. There are two separate sets of outputs, and three power outlets. And, of course, the SP14 features its own version of the hybrid technology that has made Audio Research electronics world-famous. As with every Audio Research product, SP14 parts quality, construction and factory support are the finest in the audio industry, with a two-decade track record to prove it. And all this comes at only half the cost of the celebrated SP15. FREQUENCY RESPONSEHigh-level section: ±.5dB, 5Hz to 50kHz, -3db points below 1Hz and above 200 kHz. Magnetic phono: ±.3dB of RIAA, 30Hz to 40kHzDISTORTION (THD)Less than .01% at 2V RMS outputNOISE & HUMHigh level: (1) 70 µV RMS maximum residual unweighted wideband noise at main output with gain control minimum (98 dB below 5V RMS output) (2) More than 100dB below 1V RMS input (less than 7 µV equivalent input noise). Phono: 0.12 µV equivalent input noise, IHF weighted, shorted input (78dB below 1mV input).GAINPhono input to tape output: 46 dB. Phono input to main output: 66 dB. High-level inputs to tape output: 0 dB. High-level inputs to main output: 20 dB.INPUT IMPEDANCELine inputs: 50 K ohms. Phono: 47K ohms (provisions for any value below 47K ohms or added input capacitance for matching certain magnetic cartridges.)OUTPUT IMPEDANCE250 ohms main output, 1000 ohms recorder output. Recommended load 60K - 100K ohms and 100pF. (20K ohms minimum and 1000pF maximum)OUTPUT POLARITY-MAXIMUM INPUTSMagnetic phono, 200mV at 1kHz (1000mV RMS, 10 kHz).
