There are no user-serviceable
components within the Étude
or its power supply. Dangerous
voltages/currents exist within the Étude
and its power supply, posing a severe
risk of electrocution and/or fire.
Never attempt to open,
dismantle or apply internal
third-party devices to it or
insert anything other than the listed
interconnects or speaker cables within
this user manual.
If the Étude develops a fault or
the casework becomes damaged,
immediately disconnect from the
mains power supply and connected
equipment and contact Chord
Electronics for further advice.
Before connecting the Étude to any
equipment, consult the manufacturer’s
user guide to confirm compatibility.
When connecting the Étude to any
equipment, make sure that all devices
are o, including the Étude. Once
connected, switch all equipment on
starting with the source and ending
with the amplification. Initially, operate
the Étude with your preamp/device
on its lowest gain setting and lowest
volume setting, gently increasing to
a comfortable listening level. Never
operate the Étude at excessive sound
levels; permanent hearing damage and
loss can occur.
Étude is supplied with its own
grounded 10A-rated mains IEC cable
and it is important that the amplifier is
earthed at all times via this cable, or an
appropriate alternative. Failure to do
this could be hazardous in the unlikely
event of a fault. Étude employs an auto-
sensing mains input voltage circuit and
will adjust to suit your region’s supply;
Étude will operate between 120V AC
and 240V AC -50Hz - 60Hz. Étude is
fully protected in the event of a short
circuit or fault and will automatically
shut down.
Étude’s supplied region-specific 10A
mains IEC cable can be supplemented
for an alternative power cable,
however, please make sure that it
has an earth. If any cable becomes
damaged you must discontinue use and
replace it immediately to avoid the risk
With a thick, solid aluminium chassis,
the Étude’s casework largely protects
the sensitive internal circuitryfrom
radio frequency interference.
However, for optimal performance, it is
recommended that the following points
are observed:
1. Consider placing the
Étude away from
wireless routers.
2. Separate the Étude
from amplifiers using
toroidal transformers.
3. Operate mobile phones
at a distance to avoid
interference.
Although the Étude is largely
shielded, it can generate
radio frequency interference
that may have an eect on radio and
television reception. If this occurs,
please reconsider your placement.
of electrocution.
Étude must be permanently connected
to a source of power. The included
mains lead simply plugs into the
Étude’s IEC mains socket. If the mains
lead is prematurely disconnected Étude
may still remain active for up to 15
minutes.
WARNING: Never
disconnect the
power cable during
operation. Only disconnect
when Étude is o. If the
power cable is disconnected
during operation there is a
risk of damage to connected
equipment.
