OVERVIEW

There are two types of boxes:

S

2

Power supply and diagnosis unit. Digital audio interface with two high-quality headphones outputs.

D

8

Distribution unit with 8 analog high-quality headphones outputs.

➡

A single S2 box can pilot from one to eight D8 boxes : this means 64 headphones, on a network up to 100 meters cable length.

➡

A single shielded cable with locking connectors delivers sound, power and control.

➡

Each headphone output is controlled by an individual amplifier.

➡

In the "diagnosis mode", S2 allows defaults detection when : headphones are not wellplugged, if their cable is damaged or broken or when the transducer is defective.

➡

This distribution system accepts PCM signals sampled at rates from 44,1 to 96 kHz and encoded from 16 to 24 bits using AES3 or SPDIF (electrical or optical) protocols.

➡

The system is designed to deliver the same quality and sound level to everyone in the audience. Each D8 box has an independent attenuator allowing fine level control to use a different batch of headphones on each box.

➡

Reflections of digital audio signal are prevented by using a resistance of 110 Ω at the end of the network. This impedance is activated by a switch on the last network’s box.

[PROFESSIONNAL BINAURAL SYSTEMS]

➡

Connect the S2 box with a shielded Cat-5 cable to

the first D8 box

➡

Each EtherCon® plug can be used as input or

output

➡

Connect with another shielded Cat-5 cable, the

next D8 box

➡

Connect uo to eight D8 boxes

2. Address

➡

Each D8 box must have an unique address [ID]

➡

ID 1 is set by default, except if you have bought a

complete system

➡

With a flat screwdriver, set the box ID

➡

The order in the network does not matter, but each

box must have an unique address

3. Powering

➡

4. Network termination

➡

On the last D8 box on the network, engage the button [END OF LINE]

➡

The yellow led switches on, network is ready

5. Connect the audio source

➡

Plug a digital audio source to one of the S2 digital audio inputs (44.1 to 96 kHz, 16 to 24 bits)

➡

Formats AES3 and SPDIF (RCA or TOSLINK) are supported

6. Choose the audio source

➡

Unlock the S2 unit by plugging stereo jack in one of the outputs [Phones]

➡

Push the button [volume] once. The active source name is displayed

➡

Turn the button [volume] to select the desired audio source

➡

After three seconds, push the button [volume] again, to confirm the selection

7. Adjust the level sound

➡

Unlock the S2 unit by plugging stereo jack in one of the outputs [Phones]

➡

Turn the button [volume]; the corresponding value is displayed on the screen

➡

The sound level is displayed in dBFs

➡

Level can be adjust by steps of 0.5 dBFs. Lighted point on the right side of the screen represents decimal point values

ADDITIONAL FEATURES

Setting memory

➡

To save volume control and audio source adjustments, the stereo jack must be unplugged for an instant from the [Phones] socket : The LED [S] changes to pink for one second to confirm the saving

➡

When starting, the stored settings are automatically loaded

Display intensity

➡

The button [☼ ☾] controls light intensity (digital display and LEDs) according three modes: day / night / off

➡

Pressing the button changes the intensity from strong (day) to weak (night), then only the LED [S] switches on (off mode)

➡

In off mode, any actions on button [Volume] bring back the lighting to night mode

Setting protected

➡

Outputs [Phones] of S2 boxes acts as a key. All commands (level and source selection) are locked by default

➡

Plug the stereo jack supplied or a standard headphone’s jack into the [Phones] sockets to activate controls and change audio source or sound level

AES3 input

➡

The AES3 (S2) output returns the activated audio source, No matter if the input signal comes from the AES3 or the SPDIF inputs. Link the AES3 output to the AES3 input of another S2 box to expand the network beyond 64 headphones

➡

AES3 output keeps the "Consumer" format when it copies out the SPDIF input : there is no re-encoding of AES3, only an electric adaptation of signals is done

Protection rack handles

➡

D8 box is extremely light, it can be hanged or fastened by its handles

➡

S2 box ’s handles help to protect the button [Volume]; this box is more heavy than D8 box, so we do not recommend hang or fasten the device by its handles

LEDs [1-8] and digital display inform about network’s problems

➡

[End] and blinking red: the network is not terminated or the termination is activated twice

➡

[Id] and blinking red: forbidden address are activated (0 or 9) or the same ID is used by two boxes

LEDs [1-8] indicate the status of the corresponding D8 boxes connected to the network

➡

steady blue: D8 box is activated

➡

blinking blue: audio signal is not valid

➡

steady red: D8 box indicates a power supply problem. If it appears, check the wires or the battery level. If the problem remains, contact us

LEDs [1-8] and digital display indicate the boxes using an attenuation [PAD]

➡

ADVANCED FEATURES / DIAGNOSIS

Diagnosis mode

In "diagnosis mode", the S2 and D8 boxes color LEDs display the headphones conditions. This function is available for headphones with impedances from 16 to 300 ohms. For higher

or smaller impedance, the measurement is no guaranteed.

The diagnosis mode stop the exploitation mode : the diagnosis mode mute the sound signals and the test signal is delivered to the system. This mode is designed to check and setup the installation. The diagnosis mode can be held as long as needed.

To switch to diagnosis mode, press and hold the button [Volume] for 3 seconds

➡

the word [SYS] displays

➡

to confirm press the button again

➡

sound is muted and all LEDs blink

LEDs [1-8] indicate the headphones status on D8 boxes connected to the network

➡

steady blue: 8 working headphones are connected

➡

blinking blue: at least one output headphone is still available

➡

steady red: a problem is detected on at least one headphone

LEDs [1-8] indicate status of output headphones
