Sutherland 20/20 Phono Preamplifier
It performs beautifully and brings pleasure to music lovers all over the world. The design has proven to be rock solid with long term stability and reliability.
Even after 10 years of production, there was very little that could be done to ‘improve’ the 20/20.
In one compact chassis, there are two identical circuit boards.
One for the RIGHT channel and one for the LEFT channel. Each has it’s own shielded compartment and each has it’s own power supply.
Thus it is truly a DUAL MONO implementation of a stereo phono preamp.
Over the years, there has been a steady stream of compliments on the beautifully designed circuit board. It is obviously an expression of disciplined engineering along with an artisanal passion for the smallest detail.
Even if you don’t have a technical background, the care and craftsmanship are evident.
The 20/20 has long been the ‘high value’ in phono preamps. It performs way beyond its purchase price. That aspect is even more evident in the Mk2.
Sutherland has been able to steadily grow their market without advertising expense. It’s been magazine reviews, dealer support and, most importantly, word-of-mouth reputation.
Sutherland 20/20 GAIN ADJUSTMENTS
Each channel has two configuration headers: One to select cartridge loading and an-other to select gain. Options are printed directly on the circuit board next to the configuration headers.
There are five available gain settings.
- 40 dB
- 46 dB
- 52 dB
- 58 dB (factory setting)
- 64 dB
Gain is set using the supplied, gold-plated shunts. There is a gain setting header block for each unit. Position the shunt to the desired gain value. Be sure to set the gain of each unit to the same value.
Sutherland 20/20 LOAD ADJUSTMENTS
Each channel has two configuration headers: One to select cartridge loading and an-other to select gain. Options are printed directly on the circuit board next to the configuration headers.
There are five available load settings.
- 100 Ohms
- 200 Ohms (factory setting)
- 475 Ohms
- 1k Ohms
- 47k Ohms
Loading is set using the supplied, gold-plated shunts. There is a load setting header block for each unit. Position the shunt to the desired gain value. Be sure to set the loading of each unit to the same value.
