ENGSTRÖM MONICA

MONICA er en ekte balansert forforsterker. Det kan se elegant og enkelt ut fra utsiden, men på innsiden er det valgt de beste komponenter med cutting-edge ingeniørkunst. MONICA styres via egen mobilapp. Og, matchen med LARS er lyd i verdensklasse.

First impressions place Monica’s sound firmly in the same lucid, unobstructed and communicative category that makes the Lars 2 amps so enjoyable

MONICA design details
Many of the design rules for Lars is also valid for MONICA. There are some special things in MONICA.

Gain stage configuration
The gain stage is balanced and each side is a Single Rail Push Pull circuit. In that way four triode systems are arranged for both horizontal and vertical balance. This kind of configuration has high input impedance, high gain and low output impedance.

Signal capacitors
The same type of capacitors as in Lars are used in Monica. This is Tin foil and Teflon isolation. We believe these are the best sounding capacitors.

Volume control
The volume control is built with relays and resistors in T-Pad configuration. Only 3 resistors are in the signal path at each time. The volume control has constant impedance. It is important to have a constant load on the input transformer. The volume and input selector can be remote controlled by Bluetooth. The volume setting and input are indicated on a Oled display.

Output transformer
The output transformer makes the output impedance very low. The output transformer is used in a parafeed connection. The output transformer has a core of mu metal.

Power supply
All voltages are regulated and well filtered. The plate voltage is choke filtered and tube regulated. The filament voltage is rectified by Schottky diodes for low voltage drop and low noise.
