Z1 Operating Manual
Z1 Installation
The case is connected to mains earth and
must be grounded for safety
. The ground
reference should be provided via the mains inlet or via the chassis terminal in countries
that normally use a two pin mains connector. Do not remove the ground from the mains
connector.
For installations that have separate safety and technical earth systems please consult
with Hinton Instruments before proceeding.
Earthing
WARNING: Failure to observe this practise may result in hazard
to life or damage to connected equipment.
After siting the unit connect all permanent cabling.
Z1 has four MIDI connectors on the front panel: one input, one thru, and two outputs.
Z1 may be inserted transparently in any MIDI connection scheme without any adverse
delay effects.
Connect the MIDI Out(s) to all the MIDI equipment to be controlled. If this is more than
two units, a thru box or a routing matrix should be used rather than daisy chaining via
the MIDI Thrus of each device. Connect the MIDI Out of the source equipment, master
keyboard, etc. to the MIDI In. If there is more than one source of MIDI data, then either a
selector or a routing matrix will be required. If two sources need to be combined a MIDI
data merger will be required. Hinton Instruments also manufactures a comprehensive
range of professional MIDI distribution devices.
The metal DIN connectors on Z1 may be used with twist lock type plugs as well as
the normal type. One MIDI Out should only be connected to one MIDI In, irrespective
of whether it is powered on or not. Use only quality cables intended for MIDI use and
not hi-fi cables. Cable lengths should not exceed 15 metres. Longer cables, including
special long run types, cannot be guaranteed to work in all circumstances as they have
no control over the opto-isolator type used in the receiving equipment, its sensitivity, or
its aging characteristic.
MIDI is an optically isolated system, and the cable screens are connected to the driving
circuitry ground, but not the receiver ground. Do not connect the cable screens to the
plug shells, as this will connect the case ground via the receptacle chassis and may
cause grounding related problems.
