2. Controls and Connections

3. Get started

Connect and adjust Acustom ARCH magnetic speaker stands to both speakers.

Please note that all ve [5] small magnet pads should touch the speaker dome.

(instructions also on youtube.com/watch?v=6jyWcGJzCIQ)

Set the speakers on a stable surface such a table, shelf, TV-stand, and adjust angles so that they face

the listener. Place active unit on the right side and passive unit on the left side.

Alternatively, mount the speakers on the wall using Acustom WM01 wall mount (sold separately).

Do not use the Acustom ARCH magnetic speaker stands when mounting the speakers on the wall.

3. Get started

Connect cable from (active) SPEAKER OUT to (passive) SPEAKER IN using Acustom speaker cable.

Note that RED goes RED, and BLACK goes BLACK.

Connect Acustom power cable to external 24 VDC power supply. Then connect power supply to the DC

power input on the speaker. Finally plug the power cable to power supply and the mains power socket.

Connect Analog device to the Analog Audio Input.

To turn power ON, turn to the power switch to “AUTO” (Bluetooth ON) or “ON” (Bluetooth OFF).

To turn power OFF, turn the switch to OFF.

In “AUTO” mode automatic audio source selection is active. In “ON” mode only Analog Audio Input

and Acustom Link-connections are possible.

4. Speaker placement

Acustom COAX speakers sound great placed anywhere in the room. However they are designed to sound

optimal in certain placements.

You can enjoy the best performance from these speakers when they are placed close to the wall (see

picture below). The closer the speakers are to the wall, the more bass is produced.

Ideally the speakers face the listener from the same height and distance.

There are two (2) recommended Acustom COAX speaker pair placement options:

Design set-up: Greatest décor looks

Audiophile set-up: Greatest stereo imaging

5. Basic Volume and EQ adjustments

Acustom COAX speakers are designed to sound great anywhere in the home or ofce from out-of-the-box,

with factory pre-settings.

To meet the requirements for different set-ups, other than optimal room placement, and guarantee

optimized sound – one can make adjustment with built-in EQ interface in the back-panel of the active

speaker.

To take advantage of the EQ options, please use the buttons 10-13.

5. Basic Volume and EQ adjustments

Master volume adjustment (Default: -6 dB)

To adjust master volume, please press button “+” (+3 dB) to increase or “-“ (-3 dB) to decrease the overall

output level. Room size and listening distance factor into this adjustment. [max. level 0 dB and min. level

-48 dB].

Thumb rule: the larger room or distance, the more master volume.

Master volume level indicator: When you press the “bass curve” or “treble“ buttons and release them –

indicator LED lights will light up showing the master volume level, and then turn off automatically in ve (5)

seconds.

NOTE: In Bluetooth use, one can adjust extra layer of volume separate from the master volume by pressing

“Vol+” button to increase and “Vol-“ button to decrease. Apple products automatically sync with this volume

setting. On other devices this adjustment works as separate volume control for bluetooth. Default level is

maximum.

Bass adjustment (default: Custom EQ)

To adjust bass, please press button “Bass Curve” simultaneously with either buttons “+” or “-“.

An indicator light will light up for 5 seconds based on the choice of bass curve adjustment: “Wall”,

“Desktop”, “Flat” or “Custom EQ” and “Subwoofer”.

“Wall” setting is best when speakers are mounted to the wall.

“Desktop” when speakers are on a table surface such as desktop and listener is close.

“Flat” setting is for maximum sound output used in very large spaces which require a lot of output.

“Custom EQ” default setting with bass boost (everyday use)

“Subwoofer”, setting for high-pass frequency 120 Hz (professional use). This Bass Curve setting is

recommended for using separate subwoofer. Use “Acustom Link Out” for Digital 24-bit/48 kHz Audio

output for subwoofer. Please refer to our advanced instructions or contact sales@acustomspeakers.com.

Thumb Rule: Proximity to the wall (see speaker placement) is preferred for all settings for optimal sound

quality.

Treble adjustment (default: FLAT)

To adjust treble, sound brightness, to your preference - please press button “Treble” simultaneously with

either buttons “+” to increase or “-“ to decrease. There are ve (5) Treble settings: “++”, “+”, “FLAT”, “-“

and “- -”.

6. Daily use

Acustom COAX design speakers are great for easy everyday use. With effective automated features, once

set-up, they are hassle free and you can focus on listening to your choice of audio programs – music, audio

books, and movies.

The most convenient way to use the Acustom COAX speakers is to use your Bluetooth feature on your

device for audio playback. You can also use a 3.5mm to RCA cable (cable included) to hook up any analog

source, such as your TV.

Bluetooth set-up and use

When the power is switched on with “AUTO - Bluetooth ON” option, then you can connect your Bluetooth

device wirelessly to the your Acustom COAX speaker system. You need a Bluetooth capable smart device

such as smartphone, tablet, or computer. Follow three steps below to play your audio programs.

USING BLUETOOTH DEVICES WITH COAX SPEAKERS:

Once a device is paired with Acustom speakers using Bluetooth, it remembers your relationship.

This means that you do not have to always re-pair the device.

COAX allows up to 2 simultaneous device connections. When multiple users use the speakers, Bluetooth

connections must be disconnected to allow new pairing. This will enable that other users can also wireless

play through the Acustom COAX speakers.

To switch between two active devices that are paired, one must pause or stop the playback or close the

application to have the other device take over and play audio program.

NOTE: Depending on OS, using multiple apps simultaneously may require closing some of your background

apps, to allow the current running app to take over the audio.
