Congratulations on your purchase of the Radial ChainDrive, an innovative 500 series module

that lets you distribute four balanced line-level signals to effect processors, preamps and just

about any other audio input from your 500 series rack.

Although the ChainDrive is designed to be intuitive and easy to use, we recommend that you

take a minute to read this short manual to make sure you take full advantage of the many

features that are built in. Should you ﬁnd yourself asking a question that is not addressed,

we invite you to view the ChainDrive FAQ page on our website. This is where we post the

latest hints and of course questions from users. If you still do not ﬁnd what you are looking

for, feel free to send an email to [email protected] and we will do our very best to respond

to you in short order.

Now get ready to patch, process and listen to the ChainDrive because this is what audio

engineers love to do the most!

WARNING NOTICE TO USER!

Although preventative safety measures have been designed into Radial 500 series

products we strictly advise against hot swapping modules or plugging and

unplugging them when the Workhorse or other 500 series rack is powered on. Hot

swapping can cause connection sparks at the card-edge connector that could send

damaging transients to other equipment. This also greatly reduces the life span of the

contacts. Damage due to hot swapping is not covered under warranty. There are no

user serviceable parts inside.

OVERVIEW

The ChainDrive is an innovative 1x4 ‘distro’ module designed to ﬁt inside the popular 500

series rack format. It follows convention with a 15-pin card-edge connector so that it works in

all 500 series power racks. Once connected, it enables the engineer to send four balanced

or unbalanced audio signals to various processors, effects or remote audio systems

simultaneously as a means to create innovative signal paths.

FEATURE SET

1. LEVEL CONTROLS 1 THRU 4: Used to

set the output gain for each channel on

the ChainDrive.

2. LARGE ID NUMBERS: Make it easy

to read and quick to adjust. This is

particularly important given the compact

nature of 500 series modules.

3. POWER ON LED: Convenient front

panel LED indicator lets you know the

ChainDrive is properly connected and

power is present.

4. OUTPUTS 1 THRU 4: Balanced line

¼” TRS outputs for each of the four

channels. May also be used as an

unbalanced output or a TRS stereo

out depending on the source you have

connected.

5. OMNIPORT: Unbalanced input

with auto-balancing circuitry and

priority switching. Used to convert an

unbalanced signal to balanced.

GETTING STARTED

Although the ChainDrive is extremely easy to use, we suggest you follow these simple

instructions before getting started. As with all audio equipment, always ensure all levels are

turned down and equipment is turned off before making any connections or inserting the

ChainDrive into a 500 series power rack. This common practice ensures turn-on transients

will not damage more sensitive components such as tweeters. Secure the module in the 500

rack using the supplied machine screws to ensure it does not accidentally become dislodged.

To prevent damage to the rack frame do not over-tighten the mounting screws.

Most 500 series racks are equipped with balanced XLR connectors. This is augmented with

¼” TRS and D-sub connectors if using the ChainDrive in a Radial Workhorse series rack.

When you insert the ChainDrive into your 500 series rack, it will automatically route the rear

panel XLR connections to the module’s input and output. The ChainDrive follows the AES

standard with pin-2 hot (+), pin-3 cold (-). Most devices are wired this way but older vintage

equipment should be checked to conﬁrm compatibility with AES standards.

Connecting balanced sources

Connect a balanced line-level audio signal to the ChainDrive input using a standard XLR

patch cable. The signal is distributed to the balanced TRS ¼” outputs. The ChainDrive’s

output on the rear panel of your 500 rack is identical to output-1 on the front. The level for

both outputs is set using the level-1 volume control. All outputs are variable from inﬁnity to a

maximum of +24dBu.

AUDIO SOURCE

Connect the ChainDrive’s front panel outputs to your audio devices using ¼” TRS type

cables for balanced gear or standard instrument ¼” TS cables for unbalanced, hi-impedance

audio devices. You may need to use an adapter to connect to the input of your audio devices

depending on what type of input jacks it uses. Because each output is individually buffered, it

is possible to connect to balanced and unbalanced audio devices at the same time.

Connecting unbalanced sources

The ChainDrive can distribute unbalanced line-level signals from electronic instruments like

keyboards and samplers. To interface an unbalanced audio device to the ChainDrive’s input

an adapter cable is needed that terminates in a 3-pin male XLR connector where pin-1 is

ground, pin-2 is hot, and pin-3 is left open.

Once connected, the ChainDrive distributes unbalanced signals via the four front panel

¼” outputs. Connect the outputs using standard ¼” instrument cables. The output level is

variable from inﬁnity to +18dBu with an unbalanced input.

Connecting stereo sources

The ChainDrive can also be used to distribute an unbalanced stereo signal to the four stereo

outputs. To interface an unbalanced stereo device to the ChainDrive’s input an adapter cable

is needed that terminates in a 3-pin male XLR connector where pin-1 is ground, pin-2 is the

left channel, and pin-3 is right channel.

USING THE CHAINDRIVE

How you choose to use the ChainDrive will depend on the task at hand. The ChainDrive

can distribute high quality audio signals where needed and be a handy problem solver.As a

creative tool, the ChainDrive makes experimenting easy and fun. The following are just a few

useful conﬁgurations that you can try.

Parallel processing

Parallel processing involves splitting the signal and applying multiple processors at the same

time. The output of the processors is recorded to individual tracks or mixed together to one

track. Bellow is a processing chain where a vocal track is parallel-processed through the

Radial Q4 parametric equalizer and three effects devices. The signals are mixed using the

Radial Submix 500 series line mixer.

Multiband processing

Similar to parallel processing, multiband processing uses a frequency divider (electronic

cross-over) to divide the original signal into high and low bands for separate processing and

ﬁner control. Here, the ChainDrive distributes the signal to the Radial Tossover 500 series

crossover for multiband compression using two Radial Komit 500 series compressors. An

unprocessed safety track and two effect tracks are also recorded.

Re-amping with guitar pedals and amps

Reamping instrument parts with the ChainDrive has a lot of advantages. The front panel

jacks and level controls make it especially easy to connect high impedance guitar pedals

and amps. Simply feed a pre-recorded clean track from your DAW to the ChainDrive input.

The four level controls will allow you to set the level. Connect a ChainDrive output to a guitar

amp and use a mic to record the Reamp’ed sound. Or ditch the amp completely and record

the output of a digital guitar processor. The ChainDrive will interface with all kinds of high

impedance audio devices.

Omniport hi-z to low-z converter

Ifyou are usingthe ChainDrivein a Radial Workhorse power rack, the Omniport is designated

as an unbalanced, hi-z input for line-level signals. The input is converted to a low-z balanced

signal allowing the ChainDrive to distribute signal to balanced devices. When a plug is

inserted into the Omniport, the module’s main XLR input is disabled.
