2.4 Central unit

The Interpreter System IS6 is a compact interpreter-central-unit according to the inter-

national standard ISO2603. The Interpreter System Central Unit IS6CU supplies up to 6

interpreter booths. Per interpreter booth a maximum of 3 interpreter units of one langu-

age can be connected. The internal audio-matrix administers the original signal, the 6

foreign languages and the talk-back-channel from the interpreter to the chairman. The

control elements are laid out comfortable and in step with actual practice, they cover all

necessary functions. The service personnel is clearly informed about the operating con-

dition of the interpreter unit by numerous indicators. The original signal can be adapted

to all usual line-levels via a pre-controller. The volume of the original signal can be ad-

justed via the main-controller according to the current requirements.

The control elements for the administration of the interpreter-conference-terminals (lan-

guages) are equipped with a volume control as well as a channel-allocation-display, an

active-indicator and a indicator about the usage of the talk-back-channel. Furthermore

there are 8 level-indicators to check the audio-signals.

The IS 6 Conference System from STEMIN in a 19“ – 1RU - housing provides excellent

audio quality and uses single-cable technology for easy installation.

The power is supllied via the external desktop-power-supply IS6PS1

2.4.1 Front

INPUT ORIGINAL

Rotary control to adjust the volume of the original signal according to the current requi-

rements. Treble and bass can be adjusted separately.

INTERPRETER-BOOTH 1...6

The control elements for the administration of the interpreter-conference-terminals (lan-

guages) are equipped with a volume control as well as a channel-allocation-display, an

active-indicator and a indicator about the usage of the talk-back-channel.

LEVEL- INDICATOR ORIGINAL

Level-indicator to check the level of the original signal.

LEVEL- INDICATOR CHANNEL 1...6

Level-indicator to check the level of the 6 speaking channels.

If the speaking channels are not activated the original signal is displayed.

The system's levels should be set so that the yellow "0dB" – LED lights up at level

peaks, the red „+3dB“ – LED should not light up.

LEVEL- INDICATOR SERVICE

Level indicator to check the level of the talk-back-channel.

POWER

With the rocker-switch the central unit is switched on („ | “) or off („ O ").

If the central unit is switched on the green LED „ON“ lights up. This happens with a time

delay of 2 seconds, while its internal voltage supply is stabilized.

This is not a main power switch! We therefore recommend connecting the power

supplie to a power circuit with an on/off switch. You can use this on/off switch as a

master switch for the entire system.

The LED " ERROR " lights up red if the fuse of the mainboard is defect, one of the in-

ternal fuses for the connection of the conference terminals is defect or if there’s a error

message from one of the connected conference terminals.

Hints for correction of possible defects can be found in chapter „6. Troubleshooting“.

2.4.2 Back

DC INPUT

Here either the provided desktop-power-supply DS1PS1 or any other power supply,

providing 24 - 36V, gets plugged in. Maximum current input can be up to 8A.

Make sure that the ports 0V and GND are bridged.

EXTERNAL CONTROL

Here, a information can be transferred to a interpreter unit to e.g. light up a LED.

PIN – assignment can be found in the appendix.

AUDIO OUT (Cinch)

Additional, unbalanced output for original signal, channel 1 – 6 and service and to con-

nect channel-selective recording devices (multi-channel), as e.g. Win RECX from STE-

MIN.

SERVICE

Here up to two optional service-conference-terminals IS6CP can be connected.

Therefore each IS6CP has two sockets at the back to simply loop-through the connecti-

on cable. With a service-conference-terminal switching status can be indicated or trigge-

red and „Service – Calls“ of the interpreters can be heard.

PIN – assignment can be found in the appendix.

AUDIO OUT (SubD)

Two SubD – ports to monitor the original signal and channels 1 – 6 (balanced). Both

ports are connected parallel internally. A direct connection of external monitor-amplifiers

is possible too. PIN – assignment can be found in the appendix.

INTERPRETER UNIT 1...6

Here up to 3 interpreter units per channel can be connected. Whereas only the first unit

of a booth is directly connected to the central unit, all further conference terminals are

connected in series to each other.

PIN – assignment can be found in the appendix.

ORIGINAL IN

The original signal can be adapted to all usual line-levels via a pre-controller.

With the „+20dB“ DIP-switch low level signals can be raised by +20dB. With the black

trim-potentiometer the pre-amplification can be raised by another +20dB, whereby in-

put-signals from –40dBu up to 0dBu can be processed.

If phantom power is needed for a condenser microphone, the two DIP switches

"Phant.Pwr" have to be turned over.

1 = shield

2 = audio a (+)

3 = audio b (-)

2.5 Conference terminals

The microprocessor-controlled interpreter panel IS6IU was developed for one simulta-

neous-interpreter each. Per interpreter-booth up to 3 conference terminals can be con-

nected, whereby the microphones inside one booth are gating each other, so that al-

ways only one microphone per booth is checked in. The conference terminal can be u-

sed with the integrated microphone-speaker-combination or a separately connectable

headset.

All control elements are functionally arranged, so that the conference terminal can be o-

perated intuitively. Additional the individual areas are good structured and severed opti-

cally through lines. Left-sided all elements are to be found, which are necessary for mo-

nitoring. Speaker, volume control, treble- and bass-control as well as a relay-push-

button with a selector-switch for activating the channels.

The channel-preselection-field is located on the right side. It contains the channel-

select-push-buttons with control- and busy-display for the A- and B-channel, a display to

show the activated channel as well as a change-over-push-button for the A – B – chan-

nel selection.

The microphone-push-button with LED, for optical feedback of the activated micropho-

ne, as well as the mute- (cough-) and service call-push-buttons are located centrally

since they are most frequently used.

The gooseneck of the microphone is the most sensitive part of the conference terminal,

it is not allowed to bend it beyond 90°, since this would lead to its destruction.

In order to prevent pop-noises - developed by explosive sounds such as p or t -, should

always be worked with the provided pop-filter (Acoustics-foam at the microphone).

2.5.1 Front panel

HEADSET ON

The conference terminal is able to recognize when a headset, respectively the mic-

rophone of a headset, is connected on the left side of the conference terminal and a y-

ellow LED lights up.

VOLUME HEADPHONES / HEADSET:

Rotary control to set the level of the headphones respectively the headset
