éloquence 150i Stereo Integrated Amplifier

150i Stereo Integrated Amplifier

The 150i is a compact integrated amplifier with big attitude. It has been designed with precision engineering using the latest in technological advances to ensure seamless integration into any system. The 150i won't disappoint.

Optional internal 24-bit/192kHz Digital to Analogue Converter (DAC) and Moving Magnet/Moving Coil (MM/MC) Phono Preamplifier modules ensure complete integration of digital source components (such as network music servers and set-top digital receivers), as well as turntables, into a high-performance system.

General Features

High Power Design

The 150i is designed to handle difficult speaker loads with ease. With it's high powered MOSFET design, the 150i is capable of continuously delivering a genuine 190Wrms into an 8Ω load and a huge 300Wrms into 4Ω.

High-current Custom Power Supply

At the heart of any great amplifier is a great power supply. The 150i features 2 high current independent power supplies, for controlled, quality audio.

High Damping Factor

The éloquence 150i's performance features a high damping factor. Ensuring absolute authority and control of any loudspeaker.

Advanced Microprocessor Control

The extensive range of user functions and complex functions are managed by a powerful onboard microprocessor. This gives you more control but is electrically isolated from the audio paths, ensuring faithful sound reproduction.

Advanced Stepped Volume Control

3rd generation microprocessor controlled analogue volume control. The eloquence has advanced all the benefits of a pure unaltered analogue signal path which is merely "switched" to your exact desired volume. This gives you convenience and complete control with the cleanest signal path possible.

Advanced Lossless Stepped Off-Set Balance Control

3rd generation microprocessor controlled analogue balance control. There is no loss of music quality due to the left and right volume controls being analogue "switched" independently without added circuitry. This is the ultimate in allowing you to perfectly adjust the balance volume left or right without signal loss.

Non-Invasive Protection

The 150i features sophisticated microprocessor protection for the amplifier and connected load. The protection covers over-current, over-temperature, DC offset, internal AC supply and DC fuse protection. The protection is non-invasive and does not degrade the signal path.

Balanced (XLR) input

For use with balanced sources. Enabling you to take full advantage of the benefits of balanced audio.

Home Theatre/Pass-Through Loop

Allows the integration of the éloquence into a home theatre/external system as a two channel power amp, then back to full a stereo integrated for music listening.

IR (infrared) input and output

Enables additional remote control options to be connected and controlled by the éloquence Integrated Amplifier.

Isolation Feet Options

To minimize vibrations, aftermarket "feet" can be easily attached if desired. Also, the éloquence has the ability to go from 4 feet to 3 feet to further ensure mechanical isolation
