The D-sub pin confi guration is printed on the back panel so you can
ensure the cable that is being used is properly wired. The good news
is that today, most music shops carry these types of cables and they
are usually wired correctly.

Mixer Section
The mixer section in the Workhorse features an eight channel
summing mixer with stereo outputs. It derives its signal via pin-
11 from the slot card-edge connector or from the D-sub summing
mixer input connector. Each channel features an ON-OFF switch
that enables you to select or mute the signal from the designated
card slot. Individual channel gain controls are used to adjust the mix
level while the pan control lets you position the signal across the
stereo spectrum. To assign a channel to a left or right output, one
simply hard-pans the module using the pan control. A channel-on
LED lets you know when a channel is activated plus an overload
peak indicator lets you monitor signal levels to ensure you are not
overloading the summing mixer’s input.

Mixer Master Section and Outputs
The mixer’s master section features three stereo outputs: main,
monitor and headphones, each with individual level control. The
main stereo output is equipped with TRS insert jacks for connecting
effects or equalizers and Jensen transformers that isolate the
output to reduce the hum and buzz caused by ground loops. This
is particularly useful in live recording environments where control
over the electrical system is often compromised. These also play an
important role by introducing the warm ‘Jensen sound’ at the mixers
main output. Jensen transformers are legendary in their ability to
withstand huge transients without distortion while delivering a
smooth articulated sound.

The monitor output provides a second stereo pair that can be used
in the studio for monitoring, as a direct output for recording or to
feed a PA system in a live environment. Both the main and monitor
outputs are equipped with individual on-off switches and outfi tted
with balanced XLR-male and 1/4” TRS connectors. Although both
the main and monitor outputs are balanced +4dB line level, you can
use an unbalanced ¼” cable if need be. This will of course unbalance
the signal and reduce the output by about -6dB.

Headphone Amplifi er
The Workhorse is equipped with a high-output stereo headphone
amplifi er with two standard ¼” TRS headphone connections. This
enables the engineer to share the mix and discuss the situation with
the producer while both are listening. To use, simply plug in and
adjust the level to suit.

The headphone buss is equipped with a switch that sums the stereo
image to mono. This switch only affects the headphone out and
is intended to provide the engineer with a quick reference to hear
how the mix correlates when sent as a mono broadcast. This handy
feature also helps identify stereo pairs that may be out of phase.
When set to mono, instead of summing together and getting louder,
they will get quieter and sound thin.

It is important to note that the Workhorse is intended for professional
use in high Sound Pressure Level (SPL) environments and the
headphone amplifi er is capable of producing very high audio volume
levels with most headphones. In fact, the maximum sound level
is much louder than what battery operated portable music players
can produce. Care and attention must be paid to ensure you do
not damage your hearing by setting the signal too loud. Always test
signals at a low volume before increasing the listening level.

Headphone Safety Warning
Caution: Very Loud Amplifi er
As with all products capable of producing high Sound Pressure
Levels (SPL) users must be very careful to avoid the hearing
damage that may occur from prolonged exposure. This is
particularly important as it applies to headphones. Prolonged
listening at high SPLs will eventually cause tinnitus and can lead
to partial or complete loss of hearing. Please be aware of the
recommended exposure limits within your legal jurisdiction and
follow them very closely. The user agrees that Radial Engineering
Ltd. remains harmless from any health effects resulting from the
use of this product and the user clearly understands that he or
she is entirely responsible for the safe and proper use of this
product. Please consult the Radial Limited Warranty for further
details.
