THE CONTROLS
Let’s have a closer look at what the front panel controls have to offer.
POWER SWITCH
A straight forward ON/OFF switch to turn the unit on or off.
Power is indicated by the classic Crane Song green pilot light.
INPUT SWITCH
The input switch selects between the OPTICAL, AES and S/PDIF inputs
OVER RESET BUTTON
Clears the overload LED. It also clears the peak memory value.
BYPASS SWITCH
This switch enables or disables the DSP process. There is a small time lag
when the process is turned on and off to reduce the possibility of clicks in the
audio.
SAMPLE RATE SWITCH
The clock rate can be set from 44.1KHz to 192KHz or to accept an external WC
reference. When a valid word clock is applied and WC is selected the red light
next to the switch will light to indicate lock. If lock is lost, HEDD Quantum will
default to 44.1kHz and the light will be off. Whenever the sample rate is
changed, the convertor is re-calibrated. This will keep the convertor working as
accurately as possible.
TRIODE
The triode function creates a triode tube like harmonic structure. The process
contains strong, but not strictly, even order harmonics. This affects the bottom
end of your signal by fattening it up and it should be noted that even order
harmonics are difficult to hear. The harmonic structure changes with signal
level and the amount of process being applied, just like it does in a tube in the
analog world. In the previous generation HEDD-192 his control made a low
level zipper noise when it was engaged. In the new HEDD QUANTUM, this is no
longer the case.
