Introduction

THANK YOU!...

for choosing the Manley 500/200 Monoblock Amplifiers. Designed by David Manley, the Manley 500/

200Monoblock Amplifiers use only the best available components, with the shortest and cleanest signal path possible, and with the use of our own in-house CNC machine shop we can provide you with a amplifier that looks as good as it sounds.

The circuit and the components used have been chosen carefully after years of development and refinement for reliability, constancy and most importanly, musical, accurate, and emotional delivery of the sound. The circuit topology is similar to other designs in the MANLEY range. This amplifier is configured to switch between triode or tetrode operation which allows the user to choose between the sonic benefits and seductive qualities of triode and the more powerful tetrode operation mode. We emphasize big, beefy resevoir capacitors in the high voltage supplies giving plenty of instant energy for dynamic performance of transient peaks and bass performance which often exceeds that of rival solid- state amplifiers. We run high voltages on the plates of the output tubes and are thus able to run them at lower current which will result in longer life for the output tubes. Careful use of the 'EVER-WARM' power switching should also greatly increase the life of the output tubes as well as allow your amplifiers to always be ready for pleasurable listening. Each output tube has its own bias adjust, and the procedure for adjusting each tube's current draw is described in this manual. The FEEDBACK & SLOPE controls featured on the 500/200 allow the user to optimise the amplifier-speaker interface.

The output transformer is a revolutionary new design by David Manley which is wound on the Manley Labs factory premesis. Its stellar performance will be obvious upon first listening. The secret is in keeping both phases of the push-pull halves always equal, and in this new output transformer design, David has achieved just that. The output transformer has been factory set for an optimum 5 ohm load which will drive most speakers.

Thank you again, and please enjoy!

500 / 200 WATT MONOBLOCK AMPLIFIER specifications

The Manley Labs 500/200 Watt Monoblock Amplifier is a remarkable piece of audio engineering, delivering power, precision, and a signature warmth that audiophiles have come to expect from this esteemed manufacturer. Designed for both studio and home listening environments, this amplifier stands out for its impressive sound quality and robust performance.

One of the main features of the Manley Labs Monoblock Amplifier is its high-power output. With 500 watts into a 4 ohm load and 200 watts into an 8 ohm load, it can drive even the most demanding loudspeakers without breaking a sweat. This level of power ensures dynamic range and headroom, allowing the amplifier to handle complex musical passages and transients with ease. This makes it ideal for users who crave a powerful and engaging listening experience.

The design of the 500/200 Monoblock incorporates Manley’s signature push-pull all-tube amplification topology. This results in a rich harmonic structure that adds warmth and depth to the sound. The use of high-quality, carefully selected vacuum tubes contributes to the amplifier’s ability to deliver clear, detailed audio reproduction, enhancing the listening experience whether for music, film, or live performances.

Additionally, the amplifier features a high bandwidth response, capable of reproducing frequencies ranging from deep bass notes to shimmering highs. The low-frequency response is particularly noteworthy, as it retains clarity and control without muddiness. On the high end, the amplifier shines with a smooth, non-fatiguing treble that allows listeners to enjoy long listening sessions without discomfort.

Another characteristic that sets the Manley Labs 500/200 apart is its robust construction. The chassis is built with durability in mind, using heavy-duty materials that ensure longevity and stability. The amplifier is equipped with a user-friendly interface that allows for easy operation and adjustment, accommodating various settings and preferences.

Furthermore, the amplifier features advanced protection circuitry that safeguards against overloading, ensuring safe operation even during heavy usage. This not only protects the amplifier itself but also the connected speakers, providing peace of mind for users.

In summary, the Manley Labs 500/200 Watt Monoblock Amplifier combines power, sophistication, and timeless design, making it a top choice for anyone seeking superior audio performance. Its advanced technologies, coupled with a focus on sound quality, make it a worthy investment for both audiophiles and professionals alike.
