Expect the Goldpoint SA2-47 to outperform other passive
preamplifiers with its clarity, transparency and precision.
100% passive, and
with 2 selectable inputs, the SA2 is intended to provide superior sound quality
even when replacing expensive active preamplifiers. No distortion is added to your signal path while performing
level control. (Active preamps add in a least some distortion.)
The SA2-47 has a 47-position precision stereo stepped attenuator volume control for low
noise and excellent channel-to-channel signal level matching. These attenuators use low-noise, laser trimmed, thin film resistors.
Like the Goldpoint stepped attenuator, the Goldpoint selector switch has thickly plated hard-gold switch contacts, which ensures clean, noiseless signal connections. It has two positions for two signal sources.
SA2-47 Details:
Input Impedance: 25K (Goldpoint Precision Stereo Stepped Attenuator, 47 position) Selector Switch: Selector Switch 2P-2T-1D - Two selectable sets of inputs and one set of outputs
RCA Jacks: Gold-plated, heavy duty solid brass, right angle PC Board style.
Wiring: High grade, silver-plated copper, multi-stranded with Teflon jacketing.
Chassis: Aluminum clam-shell, 1/4" front and rear panels.
Dimensions: 2.3" Tall x 4.7" Wide x 7.0" Long
Weight: 1-1/2 lbs.
The
upper SA2 rear panel shows the traditional 2 Input sets with 1 Output set.
The lower SA2R panel was designed for use as either 1 In / 2 Outs or
2 Ins / 1 Out.

About Passive Preamplifiers: Before
1980 many audio signal sources, such as tuners and tape decks, provided
only about 1 or 2 volts of output. These needed to be preamplified
before being connected to a power amplifier. When CD players came into
use in the mid 80's, they typically provided larger output voltages of
about 2 to 4 volts. It was found that these larger output voltages
allowed people to connect their new music source, the CD player,
directly to their power amplifier. In most cases, all that was needed
was the addition of some sort of volume control. A Passive Preamp is
essentially an in-line volume control. Besides costing less than active
preamps, passives can sound much better because they do not add
additional circuitry into the signal path. No distortion is added to
your audio signal. If you are really serious about great sound quality
and already have adequate signal amplitude, a passive preamp may be very
right for you. _______________________________________________________________________________________
