Leema-acoustics TUCANA II Handbook - Tucana II
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. The gain adjustment is memorised and applied whenever the current input is re-
selected. To return the gain to a nominal level, re-adjust the gain to the two top LEDs. It is recommended that the CD gain is not
adjusted, but used as a reference against which the other inputs are judged.
Balance> The balance editor allows the level of the loudspeakers to favour the left or right. This facility may be helpful if your
listening position is not ideal or if your hearing is not perfectly balanced. As with Gain, press to enter the editor and press again when
the adjustment is complete. Balance affects all inputs and the pre-amp output.
Front Panel LEDs
Various LEDs are provided on the front panel. The most obvious being the collection of thirty-two LEDs forming the volume display
ring. This ring normally displays the volume level, however, during ‘Gain’ or ‘Balance’ editing, the ring is used as an indicator for those
functions. In addition, each pushbutton is illuminated when active.
Warning LEDs
PROTECT> This LED indicates that the amplifier has entered protection mode to safeguard the loudspeakers. It is normal for this LED
to illuminate when the amplifier is first turned on. If the LED continues to flash, it indicates a fault condition and the amplifier should
be returned for service.
HEAT> This LED will flash and the unit will switch to standby if the heatsinks at the sides of the unit reach seventy degrees centigrade.
The LED will continue to flash until the unit has cooled down. During this time, it is not possible to switch the unit back on. If this situation
occurs, ensure the unit has enough ventilation and that the speakers do not have fault. The condition may also occur if very high
volumes are used for long periods, such as during a party. Warning: Avoid touching the hot surfaces of the unit!
