System Setup
This section of the manual will help you get RADAR24 up and running in your studio as quickly as possible.
Installation
Once you have unpacked the RADAR24 please make sure to keep the box and all of the associated
packaging materials. In the unlikely event that your unit needs to be returned for service or repair, using the
original shipping box will ensure that it makes the return journey in good condition.
Make sure to consider the following before installation:
! Power supply fans and hard drives make a certain amount of noise, locating the main RADAR24
unit outside of the control room is ideal.
! AES/EBU digital lines and the Session Controller extension cable can be run for about 33 meters.
! ADAToptical and TDIF digital audio connections will limit the distance between RADARand the
mixing console to approximately 10 meters.
! If you plan on using a monitor you will need an SVGA monitor and an SVGA extension cable if you
are putting RADAR24 in a machine room.
! Make sure that you have a reliable, properly grounded A.C. power source for the RADAR24. An
Uninterruptible Power Supply (UPS) is a fabulous idea!
Making Connections
Now that you’ve decided on where to place RADAR24 in your studio, it’s time to get hooked up. The exact
connections you’ll need will vary depending on the configuration of your unit so we’ve listed them all! Wiring

A.C. Power
Connect RADAR24 to the A.C. mains using the supplied power cord. The power switch is located on the
left side of the front panel. See DIAGRAM 1.0.
IMPORTANT NOTE: Make sure the VOLTAGE SELECTOR switch on the rear panel is set
to the appropriate setting before applying power to the unit. Incorrect voltage settings are
an electrical and fire hazard and can cause irreparable damage to your unit.
SCSI
Insure that the Active Terminator is attached securely to the external SCSI connector on the rear of the unit.
If additional external SCSI devices are used, remove the terminator, connect the devices and place the
terminator on the last device in the chain.
IMPORTANT NOTE: Make sure that the last device in the SCSI chain is terminated
using the supplied active terminator. Incorrect termination can cause BAD things to
happen to your audio.
Sync Reference
Sync reference is one of the keys to reliable digital audio interfacing and accurate positional synchronization.
WORDCLOCK/ VIDEO
Word clock and video sync can both be used as external clock sources for the RADAR24. The WORDCLOCK/
VIDEO-IN connector accepts either a word clock or a video sync source. The current selection in MAIN / SYNC
MENU / SYNC REF determines which of these formats will beused as the external sync source.
Word clock is a clock signal running at the same frequency as the sampling frequency of the digital audio
being transferred or recorded. It enables multiple digital devices to be locked together so that audio can be
reproduced, transferred and recorded without any digital noise or interference.

Audio Cabling
Please always use the highest quality cables with your RADAR24. The cables described below are available
on our website and in most music and pro audio stores around the world. Additionally, wiring diagrams are
available for the do-it-yourselfer at www.recordingtheworld.com.
ANALOG
Analog cables for the RADAR24 share the same wiring scheme as analog cables for the TASCAM DA-88
and other popular modular digital multitrack recorders. The RADAR24 end of each analog cable is a 25-pin
D-sub connector that carries eight independent, balanced, line level audio signals. Altogether there are six
cables required, three for input and three for output, for 24 channels of ultra-high quality analog audio I/O.
The other end of each analog cable typically breaks out to individual XLR or TRS connectors for connection
to a console’s Tape Inputs and Buss Outputs. Another often-used approach is to wire directly into a patch
bay for the ultimate in routing flexibility.
DIGITAL
There are several digital I/O options available for RADAR24 and each one has different cabling
requirements.
AES/EBU 2-CHANNEL
The cable required for the AES/EBU 2-channel interface is an XLR terminated 110-ohm digital audio cable.
One cable is required for 2 channels of input and an additional cable is required for 2 channels of output.
S/PDIF 2-CHANNEL
The cablerequired for the S/PDIF 2-channel interface is an RCA terminated 110-ohm digital audio cable.
One cable is required for 2 channels of input and an additional cable is required for 2 channels of output.
AES MULTI-CHANNEL
The RADAR24 AES/EBU multi-channel I/O uses the same wiring scheme as the TASCAM DA-88 and
other popular modular digital multitrack recorders. Both ends of each AES/EBU multi-channel cable are
terminated with 25-pin D-sub connectors. Each cable carries eight channels of input and eight channels of
output. Altogether there are three cables required for 24 channels of digital I/O. Another available cabling
option breaks out to 4 male (8 outputs) and 4 female (8 inputs) XLR connectors. This type of cable is
necessary for connecting to some types of mixers and certain digital audio workstations.

17
1717
17
TDIF
Audio: The RADAR24 TDIF I/O uses the same wiring scheme as the TASCAM DA-88 and other popular
modular digital multitrack recorders. Both ends of each TDIF cable are terminated with a 25-pin D-sub
connector. Each cable carries eight channels of input and eight channels of output. Altogether there are three
cables required for 24 channels of digital I/O.
Sync: In addition to the TDIF audio cabling requirements there is a TDIF word sync connection that may be
necessary for interfacing under certain circumstances. This connection can be made using a 75-ohm, BNC
terminated cable.
ADAT
Lightpipe connections can be made with any optical fiber that is approved for use with the Alesis ADAT
system. Each fiber carries eight channels of digital audio. Three input and three output Lightpipe fibers
provide 24 channels of ADATI/O.
Time Code
You can use either SMPTE or MTC (MIDI Time Code) formats for positional synchronization reference
with RADAR24. All industry standard frame counts and frame rates are supported.
SMPTE
SMPTE, also known as LTC or Longitudinal Time Code, is connected using the XLR LTC: SMPTE/EBU IN and
OUT connectors on the rear panel. The LTC inputs and outputs can be either balanced or unbalanced. The
LTC input has a sensitivity ranging between 100mV and 20V. The output is 1V peak to peak. This will
produce a –7 VU meter reading on a +4 device like a professional analog tape machine.
Note: When using unbalanced lines, pin 3 should be connected to the shield.
MTC
MIDI time code is input and output using the MIDI IN and MIDI OUT connectors on the rear panel of the
RADAR24.
To switch between SMPTE and MTC time code formats:
1. Press
SHIFT+CHASE(TC PREF) on the Session Controller or the KC-24 or use the MENU/PREV,
arrow keys and ENTER key to go to the MAIN / SYNC MENU / TC SETTINGS menu and press the ENTER key.

Any standard SVGA monitor (800x600 resolution) can be attached directly to the RADAR24. The monitor
connection is a 15-pin D-sub connector located on the far left of the card cage section on the back panel.
RADARLINK
RADARLINK allows multiple RADARunits to be synchronized so that they can be operated together as a
single machine. The 9-pin D-sub RLINK IN and RLINK OUT connectors used for RADARLINK are located on
the far right hand side of the card cage section on the rear of the unit. Connection between two units can be
made using the cable supplied with a multiple unit purchase or by using any 9-pin D-sub cable that is wired
pin-to-pin. These can be purchased from iZ Technology or from an electronics or computer retailer in your
area.
Note: Make sure that the cable is wired pin-to-pin! Some 9-pin cables have modified pin-outs and will not work for this
application.
Ethernet
RADAR24 ships with a 10/100 Base T Ethernet card that can be used for backing up, transferring and
exporting files. You can connect to an NT server or connect to a PC or a Mac in a peer-to-peer configuration.
The Ethernet card is located in the card cage just to the left of the Adrenalinecard, which has the active
SCSI terminator on it.
Machine Control
RADAR24 supports two formats of machine control, Sony 9-pin (RS-422) and MMC or MIDI Machine
Control. These control protocols allow RADAR24 to be controlled from other equipment like video decks

Configuration
Now that you have your RADAR24 hooked up and ready to go, we can help you make sure that the system
settings are configured correctly for your situation.
Operating Level
You can match the input and output levels of RADAR24 with the input and output levels of other pieces of
equipment in your studio. Although the inputs and outputs can be adjusted independently, all inputs share the
same operating level. The same holds true for all of the outputs.
Because a zero meter reading on a digital recorder represents the absolute maximum level that can be
recorded, a much lower nominal signal level should be specified. With analog VU meters, 0 VU represented
this nominal signal level and above that there was “headroom”, which allowed for dynamic surges and
transients. With today’s digital recorders a 0 VU signal level usually corresponds to a digital meter reading
somewhere between –14 and –20. This is where the operating level of the RADAR24 comes in. There are
four different settings for input level and four different settings for output level. They are:
+24 dBu – results in a digital meter reading of –20 when a 0 VU tone is applied

Sync Reference
The sync reference setting will vary widely depending on the application and the configuration of your system.
It will also depend on whether or not RADAR24 is the master or slave in your particular setup. You can gain
instant access to the sync settings using the SYNC key on the Session Controller and the KC-24.
To make RADAR 

24 the digital audio sync master using the word clock output:
1. Ensure that a word clock cable is connected to the WORDCLOCK/ VIDEO – OUT/THRU connector.

For digital audio transfers to a digital mixer or other digital audio device a reliable clock source is mandatory.
Without proper data synchronization digital audio will exhibit pops, clicks and other unpleasant artifacts. In a
film or video post environment video sync is usually distributed to all the video, audio and clock devices in the
studio to ensure that every thing is synchronous with the video signal right down to the sample level. For
synchronizing with analog tape decks that exhibit fluctuations in transport speed, RADAR24 can even
reference to the incoming SMPTE signal. In this configuration RADAR24 will fluctuate right along with the
analog master ensuring perfect synchronization at all times!
To slave RADAR 

24 to external word clock:
1. Ensure that a word clock source is connected to the WORDCLOCK/ VIDEO – IN connector. Make sure that
your projects sample rate in the MAIN / PROJ MENU / SAMPLE RATE dialog matches the incoming word
clock frequency.
2. Press the
SYNC key on the Session Controller or KC-24 or use the MENU/PREV key, arrow keys and
ENTER key to go to the MAIN / SYNC MENU / SYNC REFERENCE menu and press the ENTER key.
