Features Control ports allow DSP connection and Link / daisy chain expansion to other CCRM 4000 Retracta units. A positive (+2.5V to +12V) signal applied to the MASTER DSP control port will simultaneously operate all slave units connected to the master. ... -

Page 5: Connections
CONNECTIONS BLOCK DIAGRAM Important: When using a DSP to control the system make sure that the DSP control signal is already outputting to SK3 on the CCRM 4000 master (+2.5 to 12 Volts) before powering the system up otherwise the DSP command will not be recognised by the system and will fail to operate. -
Page 6: Installation
Installation The CCRM 4000 is supplied partially disassembled and simply requires reassembly / push to fit. Below is picture of the fully assembled unit. To prevent unnecessary damage to the system it’s vitally important to follow the instructions below: 1. Remove the CCRM 4000 system from its transportation box and remove the 2 foam end caps. - Page 7 To install this system a (65 mm) (2.5") hole must be cut into the ceiling tile to allow the large lower bezel just removed from the packaging to be fixed to the tile. The hole should ideally be cut in the centre of the tile and must not be closer than (76mm) (3") from the edge of the tile or it will not be possible to align the CCRM 4000 support bracket over the hole.
- Page 8 Now carefully remove from the foam packing the IR sensor, pair of metal fixing brackets with screws, remote control and 4 cable fixing kits and set aside. Next remove the top bezel containing the pulley along with the microphone and magnet assembly. 1.
- Page 9 IMPORTANT: For safety reasons the frame to ceiling tile fixing eye bolt (2 at each end of the bracket) are used to secure the frame in place and also used to suspend the CCRM 4000 and bracket. It is suggested that the cable hook is attached to the eye bolts leaving the bare wire end to a secure fixing such as a ceiling truss or any structure capable of taking 7Kgs of weight.

Page 11: Dsp Connections
DSP Connections The table below lists the pin functions for DSP control signals to the master unit. Slave units require just a daisy cable link ( standard straight RJ45 male to male cable required) between master and slave units. Check that the DSP control signal is present logic +2.5 to 12 Volts is required. -
Page 12: Mute Control
DSP Mute Control As detailed on the previous page, each unit is provided with an optically isolated open-collector output for the mute signal which is accessed through the DSP socket on the master. Muting of the microphones has to be performed by a DSP. If using IR remote then it will not be possible to mute. -

Page 15: Ir Remote Control
IR Remote control operation The remote is primarily intended to allow the initial programming of the desired height for each individual winch in the system. The preferred operation is then by logic input from a DSP logic high of 2.5V to 12V is required to release microphone to programmed height and a logic 0 low will raise the microphone. -
Page 16: Remote Control Information
IR REMOTE CONTROL ADDITIONAL INFORMATION When programming an incorrect address code for example 32 when there are only 3 units connected it will just be ignored / nothing will happen if either the up-arrow & down-arrow keys are then pressed. Wait 5 seconds and re enter the correct address code. -
Page 17: Programming Master Cable Height
Programming cable height on master unit The remote control is used to set up the cable height and also to deploy and retract the microphone. For a single unit installation (Master) this has already been factory defaulted to Master (Master unit decimal code setting is 00) ... -
Page 18: Programming Slave Cable Height
Point the remote at the IR Sensor press 01 followed by the ENTER button (green programme led on the IR sensor will light). Press the Up / Down buttons on the remote set the correct height of the microphone, press the ENTER button to store the desired height in the memory (green led will extinguish). -
Page 19: Microphone Angle Adjustment
Microphone adjustment After installation has been completed it is important to operate the unit a few times to allow the cable to settle and find its natural final rest position. The microphone can then be aligned correctly and the knuckle joint angle positioned for best audio reception. -
Page 20: Horizontal / Vertical Mounting
Horizontal / Vertical mounting Fig a shows a unit mounted horizontal using the supplied pair of metal brackets (fixed using 6 x M4 x 12 countersunk screws) and is offset to the bezel using a pulley. The Pulley is supplied and must be used if the unit is placed offset to the bezel. -
Page 21: Slave Communication Link
Slave wiring communication link connections When adding slave units to the master, connect RJ45 (straight in line connections) from socket 4 on the master to socket 3 on the 1 slave then connect socket 4 on the slave to socket 3 on the next slave in line etc etc..Audio Out Socket An XLR audio output socket is provided for connection to a mixer or DSP. -
