RP010B discontinued
The balanced members of the RP010 family — Quad Mono in the B1 version
Year: c. 2006
Status: removed from the catalog — replaced by newer generations.
RP010 → RP010B: in 2006 the RP010 family was extended with the balanced "B" versions, keeping the same architecture — Dual Mono, two power transformers, four power supplies, DC coupling, zero negative feedback, and a microprocessor watching over amp and headphone safety.
RP010 can be made in the following versions
- RP010 Classic: unbalanced RCA input, IR motor volume control, single ended output
- RP010B2: balanced XLR and unbalanced RCA inputs, single ended unbalanced output
- RP010B1: balanced XLR and unbalanced RCA inputs, full balanced and unbalanced output (balanced output requires headphone recabling)
Options available for all models: IR or manual volume control; front or rear controls and connection socket for the headphone; black or silver faceplate.
The volume control is achieved by an IR remote unit, the potentiometer is moved by a motor. The motorized potentiometer is the best possible solution for an optimal positioning — it is extremely smooth and totally noiseless, and after accurate selection the precision L-R is higher than in any stepper attenuator or digital control (digital is also very noisy).
In the B version the technology becomes Quad Mono: dynamics rise to 143 dB, the gain is factory adjustable from 6 to 30 dB, and the weight reaches 17 kg.
Prices (2006): RP010 Classic €2,900 · RP010B2 €3,250 · RP010B1 €3,500
