8-channels of
Radial's super-popular DIs!
The ProD8 is a high-density
rackmountable 8-channel direct box that is specifically designed to interface
keyboards and pre-recorded backing tracks to the PA system with redundant inputs
for live performance back-up. The ProD8's input panel is equipped with two A-B
1/4" inputs per DI channel for main and back-up sources, throughput for personal
monitoring and an effects loop that allows both A-B sources to share the same
effects for each channel. The output panel features a XLR connector, -15dB input
pad selector and ground lift witch. A 180 degree polarity reverse switch is
internally mounted and factory set with pin 2 hot.
Completely passive,
the ProD8 employs eight custom wound Radial transformers that are linear from
20Hz to 18kHz and able to withstand highly dynamic levels from sources such as
digital samplers and drum machines without flinching. To reduce interference
from outside magnetic fields, the transformers are equipped with a
mu-metal-nickel outer shield thus reducing phase distortion to an absolute
minimum. For greater system setup flexibility, the Radial ProD8 features a
reversible set of rack ears that allows the1/4" input panel or the XLR output
panels to be position at the front or back, depending on the system engineers
preference.
Passive vs. Active
DI
The Radial ProD8 ais a full range passive direct box. Active direct
boxes employ electronic circuits to change the impedance from hi-Z to lo-Z and
balance the signal. Passive DI's employ a simple passive transformer to do the
work. Active DI's require batteries, 48V phantom-power or external power
supplies to power their circuits. Passive transformer-equipped direct boxes do
not require any power to perform their task. The advantage of a transformer over
typical active circuits can be summarized as "a great device to reduce system
noise" in a sound system. to accomplish the task of noise elimination, the
Radial ProD8 features custom transformers.
Custom Isolation
Transformer
The Radial ProD8 is equipped with custom made audio
transformers, which provide exceptional signal handling without saturation. More
importanly, the ProD8's custom transforers with extremely low phase distortion
in the critical bass and mid regions. The ProD8's transformer provides 100%
isolation to eliminate hum and noise causing ground loops while maintaining
signal integrity. Inside the ProD8 you'll also find isolated XLR connectors to
eliminate chassis ground potential and a military spec PC board with full
surface ground plane to reduce susceptibility to RF noise. The result is
exceptional clarity and definition at an attractive price point.
Really Easy to Use
The best feature of the ProD8 is 'plug
& play' ease of use. All you do is connect the instrument to the 1/4"
inputs, the 1/4" through jacks to the stage amplifier(s) or mixer and the XLR
outputs to the mixing console and you are done. Any distortion? Hit the -15dB
pad. Any noise? Just depress the ground lift switch. You will find that with
acoustic guitars and basses, the natural tone of the instrument will shine
through with a smooth and musical rendering. For electrically powered devices
such as keyboards, the ProD8 will immediately eliminate troublesome ground loops
while delivering solid dynamics with a full rich sound.
