1 Overview
The CCRM 4000 product is designed for use in AV conference rooms, board rooms, court rooms, and
huddle room applications or meeting room spaces. Typically mounted in the ceiling space, it allows
the microphone to be released smoothly from the unit and drop down to a predefined height and
when not in use to smoothly retract back into the ceiling.
Designed by Clockaudio, the CCRM 4000 fulfils its goal of a reliable motorised retractable
microphone that frees up the desk space.
Major Features of CCRM 4000 includes:
 Cardioid microphones that provide an excellent front to back rejection.
 Automatic safety detection for cable hang-ups.
 Logic Hi / Lo for DSP mute detection port.
 Ceiling bezel fitted with a detection switch that allows the microphone to establish the
home position.
 Single element cardioid microphone allows a 350 degree rotation of the element with 40
degree knuckle joint angle.
 Tri element cardioid microphone allows pickup of 360 degrees.
 Automatic microphone deployment via an external positive (+2.5V to +12V) signal applied to
the Main’s DSP port or via the IR sensor. Triggering the Main unit will also deploy any other
attached Secondary units.
 Microphone output provided via a XLR socket or an RJ45 connector. If microphone was a
single element version, then output will be via an XLR connector. If it was tri element then
output would be an RJ45.
 Easy and fast connection of the audio from CCRM 4000 to mixer or DSP. A 9-48 Volt
phantom power is required.
 Expansion capability to link/daisy chain other CCRM 4000 units. Up to 99 Secondary units
can be daisy chained to a single Main unit.
 Main and Secondary units are identical in construction. Two rotary 0-9 digital decimal
encoders define and set unit’s address ID as well what it becomes – “00” for Main unit and
“01-99” for Secondary units.
 IR remote control is supplied with the Main unit. Remote control can be used to activate the
unit(s) in the absence of a DSP.
 IR receiver sensor with integral green programme mode LED and red range LED (supplied
with Main unit).
 Universal mains switched mode power supply available as separate item. Operates up to 4
units.
 Audio cable length 2.5 Metres (8.2 feet).

The CCRM 4000 is available with either a single element (C3) or a tri element (C303) microphone.
Both microphones, available in either black or white finish, provide an excellent pickup and proven
audio quality.
Definition of whether the product appears as a Main or Secondary device is defined by the settings
on the two rotary decimal encoders. If the address ID is set to 00, the unit is Main else Secondary.
It is important to note that the only difference between the Main unit and Secondary unit is that
with the Main unit, the IR receiver sensor, IR remote control and the PSU are supplied. With
Secondary units, these three items are not supplied.
The single element cardioid microphone is mounted on a knuckle joint that allows 350 degree rotation
with up to 40 degrees bend.
The tri element capsule cardioid microphone has capsules positioned at 120 degrees apart providing
a full 360 degree pickup.
For North American market, the CCRM 4000 is available with a Plenum enclosure for both the single
element and tri element microphones.

3 Installation
This section describes the installation steps required for Single and Tri Element variants.
See Section 5.4 on connecting the audio cable to the DSP.
3.1 Single Element version of CCRM 4000
To prevent unnecessary damage to the system it’s vitally important to follow the instructions
below:
1.
The CCRM 4000 is supplied partially
disassembled and requires simple push to fit
reassembly. The adjacent image shows a fully
assembled unit.
2.
Remove the CCRM 4000 system from its
transportation box and remove the 2 foam end
caps. The transportation box and packing
should be stored as this is the best packaging
to use in the unlikely event of having to return
the system to your dealer.
3.
Cut the tape securing the large cardboard box
to the large black ceiling frame.
4.
Carefully move the box out of the ceiling frame
and set to one side being careful not to snag or
cause the microphone cable to kink. Do not
remove the microphone and top bezel
assembly at this stage.
5.
Remove the small cardboard box located under
the CCRM 4000. This contains the PSU (Main
unit only).

V2.1 2021-01 Page 5 of 25
6.
Now open the large cardboard box and remove
from the packaging the microphone and large
ceiling bezel with bezel clamp.
7.
To install this system, cut a 65 mm (2.56") hole
into the ceiling tile to allow the large ceiling
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.
8.
Take the entire CCRM 4000 kit up to the final
location site. Carefully align the CCRM 4000
complete with ceiling tile bracket so that the
large slot is directly over the hole that has
previously been cut in the ceiling for the bezel.
Ensure that the front and back of the bracket
fits snugly over the ceiling tile “T-Bar rails”.
Secure the ceiling bracket to the T Bar rails
using the supplied four eye bolts finger tight.
9.
Insert the ceiling bezel up through the ceiling
tile through the hole and slot in the tile
bracket. Secure the bezel in place with the
bezel clamp using a 5mm Allen key.
10.
Now carefully remove from the foam packing
the IR sensor, remote control and safety cable
fixing kits and set aside.
Next remove the top bezel containing the
magnet assembly and Mini XLR microphone
connector.

the bezel to the lower bezel making sure the
magnet is inside the top part of the bezel.
12.
Remove any kinks or bends in the cable by
gripping the cable with your hands and pass it
through a clean dry cloth a few times. This will
straighten the cable. Connect the RJ12 plug
from the top bezel into Socket 2 (BEZEL) on the
Main unit.
13.
For safety reasons the frame to ceiling tile
fixing eye bolt (2 at each end of the bracket)
are used to secure the frame and also used to
suspend the CCRM 4000 and bracket. Unravel
the Y cable harnesses and attach the hooks to
the eye bolts at each end of the ceiling tile
bracket.

Push the free end of the cable harness through
one of the holes located on the Gripper. Now
loop the free end of the cable over a secure
fixing such as a ceiling truss, eye bolt, or any
structure capable of taking 7Kgs of weight.
Now pass the cable through the remaining hole
in the Gripper and then pull on the cable to
adjust / take up the slack. Do the same with
the other Y cable at the other end of the ceiling
tile bracket.
Cable can be slackened or removed by
inserting the supplied release key into the hole
as shown.
15.
Knuckle Joint 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.
Important: The microphone angle is limited to
40 degrees from vertical as shown.
NOTE: If the cable hits an obstruction such as a
desk / floor or is held preventing the upward
motion (0.5lbs pull) of the cable motor will
immediately stop. Remove the obstruction and
then press the up button on the remote, or up
command if using a DSP. The unit can now be
operated normally. Should this fail to restore
normal operation disconnect and reconnect
the supply Voltage to the CCRM 4000.

3.3 IR Sensor Installation
Mount the IR sensor in a position (ceiling or wall) where it will be convenient to
see all the CCRM 4000 movements whilst maintaining good line of site with the
IR sensor. Do not place any obstruction in front of the sensor as this will prevent
operation.
Drill a 16mm (5/8") diameter hole. Pass the sensor through the hole and secure it using the C clip.
Connect the cable to the IR sensor input Socket 1 (IR) on the CCRM 4000 unit.
IR sensor has 2 coloured LED’s: Green illumination while in programme mode and Red during normal
operation. The LEDs will illuminate each time a button is pressed on the remote.
3.4 Secondary unit wiring connections
When adding a second CCRM 4000 unit as a Secondary device
1.
Connect a DC supply cable between the
Main and Secondary DC input sockets.
Make sure that the correct polarity is
applied to the Phoenix plug supplied.
Use a minimum AWG 18 wire gauge to
connect DC power between CCRM 4000
units. Try and keep the cable as short as
possible.
2.
Make sure that the “Units” rotary decimal
encoder is set to other than “0” e.g. “1”
(01).
3.
Connect Socket 4 (LINK) on the Main unit to
Socket 3 (DSP IN) on the Secondary unit
using an RJ45 straight through cable.
4.
Connect the Bezel cable to Socket 2 (BEZEL)
5.
Connect the appropriate cable to the DSP –
XLR for the single element and CAT5 cable
for the tri element.
Positive (+)
Negative (–)

Page 12 of 25 V2.1 2021-01
Important: When using a DSP to control the system ensure that the DSP control signal is already
outputting +V to Socket 3 (DSP IN) on the CCRM 4000 Main unit (+2.5 to 12 Volts) before powering
the system up. Otherwise the DSP command will not be recognised by the system and unit will fail
to operate.
3.5 Further Secondary wiring connection
For addition of further Secondary units, connect a CAT5 between Socket 4 (LINK) and Socket 3 (DSP
IN) of the next Secondary. Repeat for additional units to form a daisy chain. Ensure that each
additional CCRM 4000 unit is set with a unique address using the rotary decimal encoder e.g. “2” for
second, “3” for third, etc…
Up to 99 Secondary units can be linked together in the same / identical way.

3.6 Horizontal / Vertical mounting
Apart from mounting the CCRM 4000 units in the ceiling space, these units can also be mounted on a
wall or a bracket attached to the ceiling. In either case a secure bezel attachment, where the
microphone emanates from, will need to be addressed by the installer.
Caution: When mounting horizontally on a wall or vertically on a ceiling or a support, ensure that
the correct type of fasteners are used to support the CCRM 4000. As each type of install is
different, fasteners are not supplied.
Horizontal mounting:
Using a pair of metal brackets (fixed
using 6 x M4 x 12 countersunk screws),
attach the CCRM 4000 to the wall.
Mount the bezel appropriately where
required.
Remember that the further away the
unit is mounted from the microphone
and bezel, less cable will be available for
the cable drop (cable length is 2.5
Metres max (8ft 2in.)).
Wall fixing metal brackets are available
as optional extra.
Vertical mounting:
Using a pair of metal brackets (fixed
using 6 x M4 x 12 countersunk screws),
attach the CCRM 4000 to the ceiling.
Mount the bezel appropriately where
required.
Remember that the further away the
unit is mounted from the microphone
and bezel, less cable will be available for
the cable drop (cable length is 2.5
Metres max (8ft 2in.)).
Wall fixing brackets are available as an
optional extra.

4 Controls and Connectors
On both sides of the CCRM 4000 there are controls and connectors.
Description
Connector
Power
Two +18VDC power connectors are provided. One can
be used for power In, while the other can be used to
distribute power to the next daisy chained unit.
Using Clockaudio recommended PSU, up to 4 CCRM
4000s can be daisy-chained.
Impedance matching “Z”
On each of the units is a slide switch “Z”. In a
multi-unit system of 2 or more units, it is only the final
Secondary unit that needs to have this switch ON and
all other units’ switches must be OFF.
