Page 4: General Information
TUCANA General Declaration of Conformity We hereby declare that the product to which this declaration relates, is in conformity with the following standards: EN60065, EN55013, EN55020, EN61000-3-2, EN61000-3-3. The product design also follows the provisions of 73/23/EEC, 89/336/EEC and 93/68/EEC Directives. -
Page 5: Introduction
TUCANA Introduction Introduction Congratulations on your purchase of a Leema Tucana 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 their 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 Tucana 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: Tucana Overview
Tucana overview The Leema Tucana is a very high power output, microprocessor controlled, stereo integrated amplifier. 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. -

Page 9: Connections
AUX> The Tucana'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 Tucana's volume control to be set at a higher position than would normally be required. -

TAPE OUT> Any input selection other than TAPE will automatically be fed to the tape record output sockets. The volume control on Tucana has no effect on the record output level. When TAPE is selected as an input to the amplifier, the tape record output feed is disconnected to prevent feedback. -

Tucana's volume control and can be used for a variety of uses. Examples include feeding another 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 Tucana is used to drive the tweeters in the loudspeakers and a Hydra is used to drive the woofers. -

The LED ring around the volume control will flash for a few seconds while the Tucana initialises. If mains power has not been removed from the unit, the previously used input is re- selected and the volume setting slowly raised to a low level. -
Page 13: Remote Control
Two buttons, one for up and one for down, control the volume. If using a complete Leema system, the volume of the Hydra and Cygnus will also change in step with the Tucana. Short presses on the volume buttons will change the volume in small... -
Page 14: Technical Discussion
TUCANA 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 Contrary to another common misconception, ‘timing’ cannot be compromised. The square wave performance of an amplifier is the ultimate timing test. A look at the square wave performance of a Tucana is testament to the time domain performance of the design. If multiple devices did cause errors in the time domain, the resultant square wave would be significantly degraded.

‘knows’ that it won’t be required when listening to a stereo source such as CD. Therefore, when the Hydra ‘sees’ the CD input, it powers itself down. Each Leema unit can be controlled via the LIPS bus. Controlling a Tucana externally for example, enables it to be used within a home automation system. - Page 17 Value = 40 Volume header. Valid command values are 0(mute) to 248(maximum volume) Value = 50 Serial Pass Through. When a Tucana, Hydra or Corvus receives this header, the header and value are passed on up the bus. This enables future expansion options.
