Eliminating ground/earth hum
Turntables can experience unwanted hum or buzzing related to grounding
issues from the cartridge. Huei allows you to ground your turntable using a
convenient grounding post, situated above the ‘IN R’ andIN L’ RCA posts.
You should always use the post to ground your device and eliminate noise.
To ground your cartridge, unscrew the locking earth-pin (we recommend
three turns) and locate the earthing wire from your turntable. Place the
spade tip in between the metal washers and hex bolt, before screwing back
the locking earth-pin thumb-tight. While a spade tip is recommended, if
you have bare wire, you can wrap this around the post and then secure the
locking earth-pin. Please also read Grounding plate (3.0)
Important information
Only connect Huei to a device capable of attenuating its output, such as
a preamplifier or integrated amplifier. Do not connect Huei directly to a
power amplifier. Incorrect settings could cause irreparable damage to your
equipment and hearing.
If you need support, in the first instance, please contact your supplying
retailer who will be best placed to assist you. If you need additional help
beyond that of your retailer, please visit our support page: chordelectronics.

Removing rumble noise
Huei features a Rauch Slope rumble filter that removes mechanical noise
from the turntable. It cancels out the opposing noise from each channel
whilst keeping the original music signal intact. To engage the filter, press
‘RUMBLE’ until the sphere shows white. If no colour is displayed, the rumble
filter is ‘o’.

Placement
Always ensure Huei is used in a well-ventilated setting, away from direct
sunlight and heat sources, and has sucient space around the unit.
Chord Electronics’ Qutest Stand System (available separately) has been
designed to perfectly house Huei. Otherwise, care should be taken not to
stack other units on Huei.

Setting LED brightness
It’s possible to adjust the brightness of the control spheres between two
modes:high’ and ‘low’. To cycle between the modes, simply press both the
‘MM/MC’ and the ‘RUMBLE’ buttons simultaneously.
Power connection
Huei is supplied with a 12 V, 2A external power supply (which is the only supply
that should be used). A convenient power switch above the 12 V DC input, can
be used to switch Hueion and ‘o. We recommend that this is performed with
partnering preamps or amplifiers turned ‘o’.
Connecting turntables to Huei
Huei has one stereo pair of RCAs for connection to turntables. These inputs
are labelled as ‘IN R’ (right channel) and ‘IN L’ (left channel) and are colour-
coded to facilitate connections to turntables.
Connecting Huei to your preamplifier or amplifier
Huei features variable gain to attenuate the volume for high-output
cartridges. Use the chart below to adjust the gain to a suitable level for your
preamp or amplifier. Do not adjust the gain while a signal is going through
the device. If you are unsure of which setting is appropriate, consult your
dealer. Please note that the light range will repeat after it has fully cycled.

Grounding plate
The gold-plated grounding plate, pictured, is preinstalled for your
convenience. It is required for headshells/tonearms that do not provide
a ground for both RCA connectors. It is safe to leave this in place for
normal use, however if you are using Huei with a turntable with balanced
connections then please remove the plate.
Introduction
Welcome to Huei, a high-performance Moving Magnet and Moving Coil
phono stage proudly developed and manufactured by Chord Electronics
in Kent, England. Please take a few moments to familiarise yourself with its
operation.

Connecting turntables to amplifiers
Huei has two outputs: RCA and XLR. We recommended using one output at
a time. As the circuitry within Huei is fully balanced, XLR may be preferable.
To connect Huei to the amplifier/preamp, ensure that all devices are turned
‘o’ before securely attaching interconnects to Huei and the partnering
amplifier, paying attention to the L (left) and R (right) channel markers.

Please note that the impedance of the cartridge may not t exactly within the
ranges specied; select the range that best matches. Selecting an impedance
with a 2.2uF load when using a Moving Coil (MC) cartridge dampens the ringing
of lower impedance cartridges, reducing distortion.
NOTE: IMPEDANCE CANNOT BE CHANGED WHEN IN MOVING MAGNET MODE. PRESS AND
HOLD THE MM/MC BUTTON TO ACTIVATE MOVING COIL MODE. WARNING! PLEASE MUTE
OR LOWER THE VOLUME OF YOUR PREAMPLIFIER BEFORE CHANGING IMPEDANCE.

Selecting MM or MC playback
When setting up Huei for playback, it is most important to correctly
identify and select the type of cartridge you’ll be using from the cartridge
manufacturer’s specifications. Both Moving Magnet (MM) and Moving Coil
(MC) have unique specifications and subsequently, dierent custom settings
are available within Huei’s menu.

Once Huei is connected, do not switch your preamp/amplifier ‘on’ until the
volume is at its lowest setting. Next, turn Huei ‘on’ and select the appropriate
settings for your cartridge as explained below. With the settings correct,
select the lowest gain setting on Huei (white), before turning connected
equipment ‘on’.
Next, select the appropriate input on your preamplifier, begin playing the
source and gradually increase the gain/volume to a comfortable level.
Please note that if Huei is switched ‘o’, it will remember previously selected
settings. You should only need to complete the set-up of your cartridge
during the initial installation (unless you change cartridge).
Selecting the impedance setting for your cartridge
It is only possible to select impedance with a Moving Coil cartridge in MC
mode (Moving Magnets always require a set 47 k impedance). Therefore, Ω
when in Moving Magnet mode, the ‘IMPEDANCE’ button will not illuminate.
With a Moving Coil cartridge in MC mode, select the correct impedance from
information within the manufacturer’s specifications. If you cannot identify
the impedance information from your cartridge user manual or relevant
website, please consult your supplying dealer or the manufacturer directly.
Once the impedance of the cartridge is known, use the graphical guide
below to find a suitable match and select the corresponding colour by
pressing the ‘IMPEDANCE’ button repeatedly. The impedance will increase
sequentially to Min + 2.2 uF before moving back down the range again.
MOVING MAGNET (MM) MOVING COIL (MC)
To select between Moving Magnet (MM) and Moving Coil (MC), press and
hold the ‘MM/MC’ button until the corresponding colour is selected for your
input.
