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

Page 8

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.

Page 9

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 [email protected].

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.

USING COAX SPEAKER CONTROLS FOR BLUETOOTH (OPTIONAL)

Acustom all-in-one design speakers are ready out-of-the-box for use with Bluetooth after power is switched on (AUTO - BT ON). Once a device is connected to the speakers, you are good-to-go with the controls on your device to set the volume and make song selections, to name of a few.

However, you can take advantage of the Acustom COAX back-panel controls to work with your Bluetooth audio transmission / playback from your device.

Play or pause ( ► / ►►)

To play or pause a wireless Bluetooth audio signal,

please press “► /► ►” button shortly once for both use cases.

Clear Bluetooth device list ( ► / ►►)

To clear the current list of previously paired Bluetooth devices in speaker memory,

please press “ ►/► ►” for continuously for ve (5) seconds.

Bluetooth Volume adjustment (Vol+)

You can adjust Bluetooth volume by pressing shortly button “Vol+” (to increase volume). Apple products automatically sync with the Bluetooth volume setting.

Next song ( ► )

You can play next song by pressing “ ► ” continuously for two (2) seconds.

Bluetooth Volume adjustment (Vol-)

You can adjust Bluetooth volume by pressing shortly button “Vol-“ (to decrease volume). Apple products automatically sync with the Bluetooth volume setting.

Previous song ( ►)

You can play previous song by pressing “ ► ” continuously for two (2) seconds.

6. Daily use

Television and other analog audio sources

Acustom COAX speakers connect easily to any analog audio source such as the TV. Please use the “Acustom 3.5 mm to RCA cable” (included in the box) to connect with your TV-set.

Use the headphone output on the TV with 3.5 mm connector and insert RCA connector to “ANALOG AUDIO IN” (RCA input) on the speaker. Volume adjustment should work with TV remote control. For more information please study the TV manufacturer’s instructions.

If your TV has Bluetooth, you can alternatively use that function to connect to the Acustom speakers. Volume adjustment should work with TV remote control. Please follow the instructions for Bluetooth connection above. For more information please study the TV manufacturer’s instructions.

Speakers can be connected with HDMI ARC-compatible DAC. Plug HDMI connector between HDMI (ARC) output and DAC. Plug analog audio output from DAC to COAX speaker’s analog audio input. Then, plug power supply (external PSU or USB) to DAC. Depending on TV, HDMI ARC device audio source must be chosen and CEC-function (Consumer Electronic Control) may be activated. Volume level adjustment should work with TV remote control. (HDMI ARC DAC, sold separately).

NOTE: Other analog audio sources with an output (RCA-OUT) can be connected to the speaker (RCA-IN) with a RCA-RCA cable (not included in the box).

Automatic input selection

A great feature with Acustom speakers is the automatic input selection, which makes life easy and a remote control redundant.

The COAX speakers detect when primary audio source (Bluetooth) is currently playing. When the primary audio signal is paused or stopped, the alternative audio source (Analog audio / RCA IN) takes over.

NOTE: Depending on the device and OS, you may need to close the audio application / software (e.g. streaming service app) for analog audio to take over.
