Synthesis Roma 117DC Valve Pre Amplifier

Synthesis Roma 117DC Stereo Tube Preamplifier Is Designed for Audiophiles

The Synthesis Roma 117DC Stereo Tube Preamplifier is crafted for audiophiles who seek uncompromised sound fidelity, blending a rich, analogue warmth with exacting digital clarity. With a simple yet refined design that matches the Synthesis ROMA Series, the Roma 117DC elevates sound reproduction, ensuring faithful tonal balance and exceptional depth, especially when paired with the ROMA98DC mono power amplifiers. Available in finishes like WOOD, BLACK, DARK, ALUMINUM BLACK, and ALUMINUM SILVER, the Roma 117DC combines striking aesthetics with advanced acoustic performance, appealing to the discerning listener.

High-Quality Tube Circuitry Delivers Unparalleled Audio Fidelity

The Roma 117DC preamplifier uses a sophisticated two-stage amplification system, incorporating four high-performance 6922/ECC88 tubes. This tube-based audio circuit ensures a warm and resonant sound profile, enhancing musicality and providing a responsive, immersive listening experience. The signal's balanced integrity is maintained by an input tube specifically dedicated to balancing inputs, while the output stage utilises a high-grade transformer coupling. This configuration results in extremely low output impedance, giving users flexibility with interconnect cables and allowing seamless pairing with various power amplifiers. The Roma 117DC’s frequency range spans from 5 Hz to 40 kHz at -3 dB, providing highly linear and nuanced sound.

Precision-Controlled Power Supply Ensures Signal Stability

The Roma 117DC’s power supply for both filaments and anodic sources is electronically regulated, delivering stability with a precision better than 0.1%. This regulation eliminates background noise and minimises fluctuations, ensuring a steady, clean current to the audio circuit for consistent performance. This approach allows the preamplifier to preserve signal integrity across the frequency range, while also enhancing audio clarity and reducing distortion to below 0.1% even at full output levels (20 Hz - 20 kHz @ 1V RMS).

Extensive Input and Output Options for Versatile Audio Connections

The Roma 117DC offers extensive input and output capabilities, ensuring compatibility with a broad range of audio systems. The unit includes four unbalanced RCA inputs and one balanced XLR input, accommodating various audio sources. Outputs include one balanced XLR, two unbalanced RCA outputs, and an unbalanced RCA recording output, providing flexibility for external components and allowing effortless integration into sophisticated audio setups. The Roma 117DC is capable of delivering high output levels at 36 V RMS balanced (XLR) and 18 V RMS unbalanced (RCA), with impressive gain levels of +22.5 dB (balanced) and +16.5 dB (unbalanced) to drive any power amplifier with ease.

Meticulous Component Selection for Superior Audio Quality

Each Roma 117DC is built using precision metal film resistors and premium polypropylene capacitors, selected for their reliability and sound clarity. Tubes are carefully hand-picked to minimise noise and microphonics, ensuring an undistorted soundscape and preserving the preamplifier’s exceptional dynamics. Electronic switches near the input connectors reduce signal path length, minimising crosstalk between channels and optimising channel separation, with a crosstalk rating exceeding 80 dB.

Precision Remote Control with Convenient Functions

The Roma 117DC includes a remote control crafted from anodised black aluminium, providing users with the convenience to adjust volume, input selection, and standby functions. The remote operates on an infrared RC5 protocol, ensuring smooth and reliable command response. Powered by two CR2032 batteries, this remote enables control from a distance, making adjustments easy and seamless, even in sophisticated audio environments.

Robust Headphone Output Delivers High-Fidelity Listening Experience

The Roma 117DC offers a dedicated high-fidelity headphone output, with an input impedance that accommodates headphones with impedance over 16 ohms. It provides more than 300 mW power output (32 ohms), making it compatible with a wide range of premium headphones. The headphone output retains the preamplifier’s expansive frequency response of 5 Hz - 40 kHz (-3 dB), with distortion under 0.1%, guaranteeing a pure listening experience with remarkable clarity and tonal balance.
