Introduction 1.1
DAVE is an incredibly
powerful and versatile
digital-to-analogue
convertor preamplifier and
headphone amplifier.
Before operation, we strongly
advise you read this user manual
thoroughly.
We also recommend that you
store this user manual, along with
your original receipt of purchase,
in a safe place should you require
assistance in the future.

Protection against
liquids & heat
1.2
DAVE is not protected
against liquids of any
kind. Never place
containers of liquid on DAVE.
Never allow DAVE to come
into contact with moisture or
liquids; doing so could result
in electrocution or damage to
DAVE’s internal circuitry.
Be aware that liquids, including
water that has dried, can leave
minerals that can aect the
PCB and other components,
which could eventually lead to
oxidisation and short-circuiting.
If DAVE comes into contact
with moisture or liquids,
immediately disconnect from
the power supply and connected
equipment, and contact Chord
Electronics for further advice.
DAVE has internal
thermal protection
which will shut down
the unit in the event of excessive
temperatures being reached.
Never operate DAVE near
sources of heat or naked flames
as this will decrease the lifespan
of the internal components.
It is advised that you do not
operate DAVE in an area of direct
sunlight or on top of significant
heat-producing devices.
Please be aware that it is entirely
normal for DAVE to become
warm during use.
If you are concerned about the
temperatures, please switch the
device o or consider a dierent
placement.

There are no user-
serviceable components
within DAVE or its power
supply. Dangerous voltages/
currents exist within DAVE 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 headphone
adapters within this user manual.
If DAVE develops a fault or the
casework becomes damaged,
immediately disconnect from
the power supply and connected
equipment, and contact Chord
Electronics for further advice.

Dismantling & radio
frequency interference
1.3
With a thick, solid aluminium
chassis, DAVE’s casework
largely protects the sensitive
internal circuitry from radio
frequency interference. However,
for optimal performance, it is
recommended that the following
points are observed:
1. Consider placing DAVE away
from wireless routers.
2. Separate DAVE from
amplifiers using toroidal
transformers.
3. Operate mobile phones at
a distance to avoid
interference.
Although the unit is
largely shielded, it
can generate radio
frequency interference that
may have an eect on analogue
radio and television reception.
Please consider moving DAVE to
a dierent location should this
happen.

_
Before connecting DAVE to any
third-party equipment, consult
the manufacturer’s user guide to
confirm compatibility.
When connecting DAVE to any
equipment, make sure that all
devices are o, including DAVE.
Once connected, switch all
equipment on starting with
the source and ending with the
amplification.
Initially, operate DAVE on its
lowest volume setting, gently
increasing to a comfortable
listening level.
Never operate DAVE at excessive
volume levels; permanent hearing
damage and/or loss can occur.
DAVE does not have internal
batteries and, therefore, must
be permanently connected to a
source of power.
The included 10-amp IEC power
cable plugs into DAVE.
Do not disconnect DAVE from
the power cable without first
switching the unit o to avoid
any damage.

Never disconnect the
power cable during
operation. Only
disconnect when DAVE
is o. If the power cable
is disconnected during
operation, there is a risk
of damage to connected
equipment.

Whilst DAVE will operate
normally on top of a rack or side
table, it is recommended that the
device is allowed to
‘breathe’.
Allocating 10cm of space around
the device to convection-cool
during operation is advised.
As the infra-red remote
control requires a direct
line of sight to the
viewing portal, avoid placing
objects on top of DAVE or
putting it within enclosures.
