ZEUS II H-QX series User manual
3)^AC POWER CABLE AND AC VOLTAGE
H-QX Series amplifiers is set to suit the specific AC voltage. Products can safely work
under the normal variation range of AC voltage, but rated performance can be only
reflected at rated voltage.
Note: If you happen to damage the AC line-cord, always use a three-pin plug
with a ground pin. The wire correspondence is as follow:
Cable
Pin
International
Brown
Live
L
Blue
Neutral
N
Yellow/Green
Earth
Always connect the earth! Pay attention to your safety!
Before taking into operation for the first time, the installation has to be approved by an
expert.
4)^VENTILATION GRILLES
These grilles allow constant ventilation between the front and back of the amplifier. It is
suggested not to obstruct these grilles.
5)^OPERATION MODE SELECTORS
These are three-position switches that allows you the selection of BRIDGE, STEREO or
PARALLEL operation modes for the two amplifier sections (CH1 / CH2 - CH3 / CH4).
6)^LINK SWITCH CH3/CH1
By putting this switch in the ON position, you can configure the amplifier with 1 input
and 4 outputs in PARALLEL MODE and with 1 input and 2 outputs in BRIDGE MODE. In
both cases CH1 must be the input signal. The volume adjustment for the outputs will
be made via CH1 and CH3 level controls.
7)^GROUND/LIFT Switch
The ground/lift switch eliminates unwanted hum and buzz by interrupting the ground
loops between equipment, preventing current flow along the cable shield between two
devices.
8)^GAIN SENSITIVITY SELECTOR
This three-position switch allows you to select the sensitivity of the input signal so that
you always have an adequate margin (Headroom) between the nominal level of a signal
and the maximum level that the amplifier can handle correctly before saturation occurs
with consequent signal reduction. This selector allows to choose, as the input sensitivi-
ty, 0,775V, 1,4V or 2,5V.
