Introduction 1.1

PRIMA is a device that

converts your sources to

705.6 or 768kHz 24-bit

PCM and achieves reconstruction

of the original analogue signal in

the ADC to a better than 16-bit

accuracy under all conditions.

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

Prima is not protected

against liquids of any

kind. Never place

containers of liquid on Prima.

Never allow Prima to come

into contact with moisture or

liquids; doing so could result in

electrocution or damage to the

Prima’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 the Prima comes into contact

with moisture or liquids,

immediately disconnect from

the mains power supply, and

connected equipment and

contact Chord Electronics for

further advice.

The Prima has internal

thermal protection

which will shut down

the unit in the event of excessive

temperatures being reached.

Never operate the Prima 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

the Prima in an area of direct

sunlight or on top of signiﬁcant

heat- producing devices.

Please be aware that it is entirely

normal for the Prima to become

warm during use, particularly

within a stacked conﬁguration.

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 the Prima or

its power supply. Dangerous

voltages/currents exist within

the Prima 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 the Prima 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.

Dismantling & radio

frequency interference

1.3

With a thick, solid aluminium

chassis, the Prima’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 the

Prima away from

wireless routers.

2. Separate the Prima

from ampliﬁers using

toroidal transformers.

3. Operate mobile

phones at a distance

to avoid interference.

Although the Prima

is largely shielded, it

can generate radio

frequency interference that

may have an eect on radio

and television reception. If this

occurs, please reconsider your

placement.

PRIMA | Manual

Before connecting the Prima

to any equipment, consult the

manufacturer’s user guide to

conﬁrm compatibility.

When connecting the Prima to

any equipment, make sure that

all devices are o, including the

Prima.

Once connected, switch all

equipment on starting with

the source and ending with the

ampliﬁcation.

Initially, operate the any

connected equipment on its

lowest gain setting and lowest

volume setting, gently increasing

to a comfortable listening level.

Never operate connected

equipment to the Prima

at excessive sound levels;

permanent hearing damage and

loss can occur.

The included 15V 4000mA

power supply simply plugs into

the Prima.

If the power supply is

prematurely disconnected Prima

may still remain active for up to

15 seconds, however, this may

cause damage to connected

equipment.

Never disconnect

the power cable

during operation.

Only disconnect when Prima

is o. If the power cable

is disconnected during

operation there is a risk

of damage to connected

equipment.
