Reference-Level Monoblock Power for Demanding High-End Loudspeakers
The Advance Paris X-A1200 Mono-Block Power Amplifier is engineered for high-end systems where maximum power, channel isolation and loudspeaker control are priorities. Each X-A1200 powers a single audio channel, eliminating interaction between left- and right-channel power supplies and amplification stages. With 450 watts RMS into 8 ohms and more than 700 watts into 4 ohms, it provides exceptional current capability for large, demanding and low-sensitivity loudspeakers.
At the heart of the X-A1200 is an oversized 1,000VA toroidal transformer paired with two high-current diode bridges and twelve 10,000µF capacitors for a total filtering capacity of 120,000µF. Ten high-current NJW0281G and NJW0302G output transistors provide the power stage, while selectable High-Bias operation allows the amplifier to reproduce its first watts in Class A before progressively transitioning into Class AB as output requirements increase.
Highlights & Benefits
-
450W RMS into 8 Ohms — Massive single-channel output provides exceptional dynamic headroom and control, with more than 700 watts available into 4-ohm loads.
-
True Monoblock Architecture — Each amplifier powers only one loudspeaker channel, eliminating interaction between left- and right-channel amplification and power-supply circuits.
-
1,000VA Toroidal Transformer — An oversized power supply provides the current reserves needed for demanding loudspeakers and large dynamic swings.
-
120,000µF Filtering Capacity — Twelve 10,000µF capacitors provide substantial stored energy for transient response, bass authority and amplifier stability.
-
Selectable High-Bias Operation — Allows the first watts of output to operate in Class A before the amplifier automatically and progressively transitions into Class AB.
Technology & Design
Ten High-Current Output Transistors — NJW0281G and NJW0302G bipolar power devices provide the current capability necessary for substantial output into demanding loudspeaker loads.
Oversized Power-Supply Architecture — A 1,000VA toroidal transformer, dual power-diode bridges and 120,000µF of filtering capacity form the foundation for the X-A1200's high-output performance.
Class A / Class AB High-Bias Operation — A rear-panel High-Bias switch increases output-stage bias so the amplifier operates in Class A for its initial watts before transitioning progressively into Class AB.
Compartmentalized Internal Chassis — Separate internal sections improve chassis rigidity and provide additional isolation between critical power-supply and amplification circuits to help minimize interference.
FAQ — Advance Paris X-A1200
Is the Advance Paris X-A1200 sold individually?
Yes. This listing includes one X-A1200 monoblock amplifier. Because each amplifier powers one channel, two X-A1200 amplifiers are required for a conventional two-channel stereo system.
How much power does the X-A1200 produce?
The X-A1200 delivers 450 watts RMS into an 8-ohm loudspeaker load and more than 700 watts RMS into 4 ohms.
Does the X-A1200 have balanced inputs?
Yes. The amplifier provides both balanced XLR and unbalanced RCA input connectivity, allowing it to be paired with a broad range of high-end preamplifiers.
What does High-Bias mode do?
High-Bias mode allows the first watts of amplifier output to operate in Class A. As greater power is required, the amplifier automatically and progressively transitions into Class AB operation.
