    Audio Specifications ............................ 16 Introduction Congratulations on your purchase of a Leema Tucana II amplifier. The Leema product range has been painstakingly engineered in the United Kingdom to offer genuine state-of-the-art performance. Users should read and follow this instruction manual, paying particular attention to the user installation and safety advice sections.

    VERY IMPORTANT Before connecting your new Leema Tucana II to the rest of your system, please ensure that the loudspeaker cables are correctly and firmly attached to the binding posts on the rear of the unit. All required sources should also be connected BEFORE inserting the mains power lead and powering for the first time.

  • Page 6: Installation & Safety Advice

    User installation and safety advice Please ensure that the mains voltage of your new Tucana II amplifier is correct for your region. The setting is displayed on a label next to 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.

    CD> The Tucana II’s CD input should only be connected to the analogue outputs (usually marked left/right and colour coded white/red) of the CD player. DO NOT connect any available digital outputs from the CD player to the input terminals of the Tucana II, as damage to the speakers is likely to occur.

    However, unlike other systems, the volume control on the Leema system is still active and can be adjusted away from the pre-set point as a safety feature. Selecting another input on the Tucana II and then re- selecting the AV DIRECT input, will reset the gain point.

    PRE OUT> These outputs are controlled by the Tucana's volume control and can be used for a variety of uses. Examples include feeding an active subwoofer and bi-amping, where a Tucana II 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 Tucana II initialises. If mains power has not been removed from the unit, the previously used input is re-selected and the volume setting is slowly raised to a low level.
  • Page 12 TUCANA II Controls Gain> Pressing ‘Gain’ allows the gain of the currently selected input to be varied over a range of +/-10dB. This is ideal for boosting the level of quiet sources such as MP3 players and tuners, to better match that of CD players etc. When you have finished adjusting the gain, press the button again to leave the editor.

    TUCANA II Remote control Remote control Power> The red power button turns the unit on from standby, or reverts to standby from power on. When powered on, the volume ring will flash while the unit initialises then, if applicable, the previous input setting will be restored and the volume will slowly rise to a low level.

  • Page 14: Technical Discussion

    TUCANA II 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 a 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 II 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.

    ‘sees’ the CD input, it powers itself down. Each Leema unit can be controlled via the LIPS bus. Controlling a Tucana II externally for example, enables it to be used within a home automation system. An interface between LIPS and RS232 is available for installers and system integrators.

This header is private and must not be issued by any controlling software. Value = 30 This is a general command header. The command values are as follows: 10 = Infra Red control OFF.

    LIPS leads are directional. The direction is governed by the plug colour. Remember - ‘Black out, Red in’. Tucana II as LIPS slave: If you own a Leema CD player, it will normally be the master. In this case, connect the black plug to either LIPS socket on the player and the red plug to either socket on Tucana.
