Directive(s): 2006/95/EC The Low Voltage Directive 2004/108/EC The Electromagnetic Compatibility Directive hereby declare that: Equipment Hi-Fi Integrated Amplifier Model Name Pulse III is in conformity with the applicable requirements of the following standards Standard. No. -
Page 5: Introduction
PULSE III Introduction Introduction Congratulations on your purchase of a Leema Pulse III amplifier. The Leema range of products has been painstakingly engineered in the United Kingdom to offer genuine state-of-the-art performance. Partnered with suitable equipment, Leema amplification will provide audio performance far beyond that of competitors and will equal or better the performance of products costing many times their purchase price. -
Page 6: Safety Advice
User installation and safety advice Please ensure that the mains voltage of your new Pulse III amplifier is correct for your region. The setting is displayed on a label below the mains power inlet. The mains voltage setting is not user adjustable, therefore the amplifier must be returned to the manufacturer if any changes are required. -
Page 7: Pulse Overview
Pulse III overview The Leema Pulse III is a high power output, microprocessor controlled, stereo integrated amplifier and high-performance DAC. It is capable of class-leading performance at the heart of an audiophile stereo system, but thanks to the LIPS (Leema intelligent protocol system) interface, it can also be the centre of a stunning home cinema or surround music system. -

TUNER. AUX> The Pulse III's AUX input can be connected directly to any line level analogue stereo outputs. Some devices such as MP3 or hard disk based portable players have a comparatively low output which will require the Pulse III’s volume control to be set at a higher position than would normally be required. -

Connections Selecting another input on the Pulse III and then re-selecting the AV DIRECT input, will reset the unity gain point. TAPE> The Pulse III’s TAPE input should be connected directly to the analogue outputs (usually marked left/right and colour coded white/red) of a recording device such as a tape machine or PC audio card. -

Pulse III's volume control and can be used for a variety of uses. Examples include feeding an amplifier in another room for a simple multi-room system, or as a line level feed to a subwoofer. They can also be used for bi-amping, where a Pulse III is used to drive the tweeters in the loudspeakers and an additional amplifier is used to drive the woofers. -

PULSE III Controls Cables Never underestimate the importance of good quality speaker cables, bell wire or lighting flex will simply not do. The higher the system resolution, the more easily the differences between cables can be discerned. Leema recommend the use of high quality bi-wire cables with your new amplifier to ensure optimum fidelity. -
Page 13: Remote Control
PULSE III Remote control Remote control Power The power button (small red button) turns the unit on from standby or reverts to standby from power on. When powered on, the unit initialises then, if applicable, the previous input selection will be restored and the volume will fade up to a low level. -

PULSE III Topology Technical Discussion Topology Starting with the pre-amp and control stage, input selection is performed by gold over silver contact relays under control of the microprocessor. The audio is then buffered by audiophile quality OP275 amplifiers in order to present the Burr Brown precision attenuators with a low impedance drive signal. - Page 15 The resulting amplifier has the following characteristics: Low noise Very low distortion, typically better than class leading class A designs High output current delivery Low output impedance Fast and detailed yet silky smooth audio presentation High robustness and reliability Pulse III power-amplifier 1KHz Square Wave performance...
