Page 3: Safety Operation
1. SAFETY OPERATION Firstly, thank you very much for using LINEARCOM3000 conference system. To make sure safety of equipment and user, please read this safety instruction carefully before installing and using and operate seriously according to this manual. Also please keep this safety instruction for future reference. -
Page 4: System Introduction
2. SYSTEM INTRODUCTION Brief introduction LINEARCOM3000 is a series product of digital infrared language distribution system. It uses both digital infrared audio transmitting and control technique and an IR digital infrared chip. They own LINEARCOM3000’s intellectual property. IRRC08 can be used in simultaneous interpretation systems for multi-language conferences. -
Page 5: System Composition
System composition The system consists of a number (N) of audio sources, either analogue or digital, which are connected to a transmitter. The transmitter processes the audio signals into an electrical output to feed the infrared radiator. The infrared signal is received by the infrared receiver that processes the signal and outputs an audio signal and/or associated data. - Page 6 Carriers System is transmitting within the 2 ~ 8 MHz frequency band. It can transmit up to 8 different carrier signals (depending on the transmitter type) Carriers 0 to 5 are according to IEC 61603-7. Aspects of infrared distribution A good digital infrared language distribution system ensures that all delegates in a conference venue receive the distributed signals without disturbance.
- Page 7 The direction and sensitivity of receiver unit The sensitivity of a receiver is at its best when it is aimed directly towards a radiator. To minimize the disadvantage of this aspect, IRRC08 receiver adopts an ingenious structural design with peculiar 270° ultra wide angle to get perfect IR capture and sound quality at any disposition.
- Page 8 If the path of the infrared signals is blocked, e.g. under balconies, at least one additional radiator is needed to cover the ‘shaded’ area. Overlapped footprints and multi-path effect If footprints of two radiators overlap, the total coverage area maybe larger than the sum of the two separate footprints.
- Page 9 Increased coverage area caused by added Reduced coverage area caused radiation power differences in cable signal delay The lower the carrier frequency, the less susceptible the receiver is for differences in signal delays. The signal delays can be compensated by adjusting the delay compensation switches on the radiators.

- Page 12 To digital conference system Interpretation system controller can be connected via audio input on infrared controller. Interpretation controller has auto-editing number, connection checking, online list display functions. To external audio sources System controller has up to 32 channels audio input (depends on controller type) for connecting to external unbalanced audio sources (such as other brand conference systems) or for music distribution.
- Page 13 To free mode audio input Infrared controller has 1 free mode audio input which is used for music audio signal input. Configuration and operation Infrared main unit can be set up via menu on LCD display and 5 dimensional keys. Below are detailed operations.
- Page 14 Working modes There are 3 working modes in main unit : Meeting mode, urgent mode and free mode. You can set up on standby interface directly. Press left key to enter urgent mode; press right key to enter meeting mode; press down key to enter free mode. FREE MODE URGENT MODE MEET MODE...
- Page 15 Channel shielding : Setup the number of output channel. For example, 16-channel controller can be set to 4, 8, 12 or 16 channels. Shown as below, 16 channels controller will display as 4 channels output on the “conference model” of start menu when the channel shielding is set to 4-channel open.
