Leema-acoustics Hydra Handbook - Hydra
surround system which is bi-amplified, consisting of a Tucana with it’s partnering Hydra covering front left and right duties, a pair
of Hydras for the surround left and right channels and a Corvus and Hydra for the front centre. The Hydras would then need to
power on and off in the correct sequence with their partnering units. Thankfully, their power on status can very easily be re-
programmed. Simply select the required input on the Tucana, then press and hold the standby button on each Hydra you wish
to associate with that input until it’s information ring flashes once and the desired Hydra powers up. Repeat the Hydra re-
programming sequence for each input selection on the Tucana. The Hydras will now power on correctly for each input source
selection as desired.
Volume control
The volume control is in fact a high quality Burr Brown precision attenuator operating under microprocessor control. The ring of
blue LEDs, act as a visual indication of the volume setting. This has the advantage that it is clearly visible when viewed from a
distance or when using the remote control. This method of volume control permanently ensures the highest fidelity without the
gradual degeneration of conventional motorised volume controls. The volume attenuator also controls the Pre-out and Bi-amp
out volume levels.
