ABOUT THE “A” Range

Trident Recording Studio’s started operations back in the 1960's as a recording studio. Many things came out of the
Recording Studio that led to what Trident Audio Developments is today.
Trident Recording Studios recorded legendary bands like David Bowie, The Beatles, James Taylor, Queen, Supertramp,
Mott The Hoople, Bad Company, Free, Rush, Elton John, Manfed Mann, T-Rex and so many more, we simply do not have
the space to list them all here. These recordings were done by incredible recording engineers like Roy Thomas Baker,
Ken Scott, Tony Platt, Tony Visconti, Adam Moseley, Dave Hentschel, and many others. Trident Studios was the place
known by the very famous bands as the place to record in London.
Trident studios was the first studio to acquire the first ever 8 Track from Ampex. No one in London had an 8 Track…not
even EMI. When Trident got its first 16 track recorder, they decided to buy a new recording console but simply could not
find any commercially available console to do 16 track recording with the feature set they needed. It was decided by the
powers to be at Trident that between the recording engineers, and the technical staff under the direction of Barry Porter,
Trident would attempt to build their own custom console.
The first console was designed purely for Trident Studios and was designated the 'A' Series. It was hand built to the need
of the facilities and designed to be ergonomic. In those days, the integrated circuit (i.c.) had not been invented, so all of
the circuits used individual transistors (known as discrete design). This and the use of inductors in the lower and upper
mid equaliser sections are said to account for much of the unique sound of the 'A' Series. From this first successful
design was borne Trident Audio Developments Ltd, which went on to become a leading manufacturer of music recording
consoles. One of the company's earliest advertising slogans was 'designed by recording engineers for recording engi-
neers'. This became a key component of what made the 'Trident Sound' unique. As a recording engineer rather than an
electronics engineer, Trident Audio Developments was designed by the engineers ears, rather than a text book of
electronic design, and it is this, coupled with over thirty years experience that has enabled Trident Audio Developments
to develop its own 'philosophy of sound' that is Trident's trademark.
The “A” Series eventually led to the development of the “A“ Range Console, which became the console everyone wanted
to work and record on. The “A“ Range was quickly labeled as the best sounding console ever. Today, PMI Audio has
created a two channel version of the A Range Mic Preamplifer and the “A“ Range 4 band EQ of the console and housed it
in a 2U 19” Rack unit. This new dual channel unit is an exact replica of the original all discrete transistor circuitry, and it
faithfully follows the original electronic circuit design to the absolute degree. So much so that it has taken three years of
circuit analysis and testing by PMI Audio’s designers and many of its former engineers who undertook the mammoth
task of recreating the original’s designs. Needless to say, Trident Audio Developments and PMI Audio are extremely
pleased and proud to offer this unique piece of recording history.
There were only thirteen A Range consoles ever built back in the 1970’s, and almost all of them have been rebuilt and
are still in use today, despite being nearly forty years old. This says a lot about the heritage of these iconic items of
recording equipment and the artists that have used them.
We hope you will enjoy the A Range as much as we have enjoyed designing it.

Trident A-RANGE Product Description
The A-Range® is a 2-channel rack-mountable version of the legendary Trident ‘A’ Range console. Comprising two
independent channels, each with a microphone/line amplifier and four band equaliser, it is designed to process
incoming signals from a microphone or line level instrument and output to a recording device, such as a digital au-
dio workstation or analog multi-track tape recorder. Mains powered, with 48 volt phantom power independently
switchable for the two channels, the A-Range® operates as a complete stand-alone unit.
In keeping with its mixing console heritage, each ‘channel strip’ of this rack unit features insert points (switchable
pre/post EQ and with bypass), phase reverse (which operates on both microphone and line inputs) and an output
level control with peak signal indication. All inputs and outputs are balanced so that maximum signal integrity and
high output levels are assured with minimum distortion.
A useful additional facility when using it as a stand-alone unit is the inclusion of LED peak level indicators at key
points in the signal chain. These are located: directly after the input amplifiers (microphone and line), after the
equaliser section and after the main output amplifier. This ensures that the signal is accurately monitored and
matched at all stages in the signal chain.
The A-Range® rack will add its own signature to any programme material, whether using just the discrete transis-
tor microphone and line input preamplifiers or the unique and versatile equaliser sections.
Connecting The Unit
The rear panel of the unit provides both XLR and 1/4”” jack inputs for the line input and output of each channel
while a separate XLR is provided for the microphone input. The insert sends and returns are 1/4” jacks. The XLR
connectors use the standard industry convention of pin 1 ground, pin 2 positive and pin 3 negative. The jacks are
tip-positive, ring-negative and sleeve ground. For unbalanced use, connect the ring to the sleeve.
When connecting a microphone, set the ‘Input Level’ control for each channel to minimum, with the phantom
power +48V switch o (LED extinguished). The microphone input is designed to accept the signal from low im-
pedance, balanced microphones of either dynamic, ribbon or condenser types. The line input is designed to ac-
cept balanced or unbalanced, line level audio signals. Mic or Line input is selected via the front panel ‘Line’ switch
(LED lights for ‘Line’). The outputs from each channel are low impedance and designed to operate with long cable
runs without signal degradation. A standard IEC mains inlet is provided for AC mains power. Operating voltage of
either 120 or 240 volts is selectable by rotating the fuse holder incorporated into the mains inlet socket.

Trident A-RANGE Owners Manual4
Trident A-RANGE Description
Input Section
The input section of the A-Range® rack consists of a very high quality transformer-coupled discrete microphone
amplifier and transformer-coupled discrete line amplifier designed specifically for professional audio applications.
The microphone and line transformers are custom designed to the exact original Trident A-Range specifications.
The microphone amplifier is designed to handle signal levels from -60dBu to as high as +10dBu without needing a
separate pad switch. The 15-position combined mic/line gain switch is calibrated in accurate 5dB steps to provide
precise matching of either microphone or line level signals. In conjunction with the ‘Output’ level control, very
fine adjustment of signal level is achievable. The preamplifier exhibits very low noise while maintaining extremely
fast transient response and a frequency response that extends beyond 40kHz. Naturally, best results are achieved
when using a high quality condenser microphone. The microphone amplifier will also bring out the best in dynamic
and ribbon microphones.
When connecting a microphone to the input of the unit, set the ‘Input Level’ rotary switch to its minimum (‘0’)
position and the ‘Output’ level control to its ‘0’ position. The ‘Line’ switch should not be depressed. If required,
engage the ‘+48V’ phantom power switch while the ‘Input Level’ control is at minimum. The associated LED will
show that phantom power is present. Allow up to 30 seconds for the microphone to reach normal operating level
and advance the ‘Input Level’ control until a suitable level is achieved at the output of the unit. The ‘O/P peak’ LED
signal indicator at the output stage of the circuit is designed to light when a signal level of +15dBu occurs at the
output stage. This provides plenty of overload margin as the A-Range® is capable of very high output levels (up to
+26dBu) into a balanced load. However, by setting the level as described above, adequate headroom is maintained
and there should be no danger of overloading following equipment.
The phase (polarity) reverse switch is employed when phase interference occurs between multiple microphones.
Such interference results when microphones, at various placements, pick up the same sound source at slightly
dierent times. When the output of the microphones combine, cancellation occurs at certain frequencies. This
eect is known as comb filtering. Switching the polarity on one microphone may serve to minimise this eect.
When using a line level signal, the ‘Line’ switch should be depressed (LED illuminates) and the ‘Input Level’ control
switched to ‘0’. +48V phantom power should never be selected in the ‘Line’ mode as this can cause a loud noise
when the phase reverse switch is operated. In this position with the ‘Output’ level control also set to ‘0’, the unit is
designed to give unity or 0dB gain. The line input gain can be adjusted in accurate 5dB steps in the same way as
the microphone amplifier. However, the line input adjustment only operates between the +10 and -10 positions of
the switch. In all other positions, the line input reverts to zero or ‘unity’ gain.

Trident A-RANGE Owners Manual5
Trident A-RANGE Description
Operating the Equalizer
Set the ‘Input Level’ in accordance with the procedures detailed in the ‘Input Section’ section of this manual. Begin
with all boost/cut faders set to their mid way (‘0’) positions. Adjust the low and high mid frequency controls to
their minimum positions (fully clockwise). The high and low pass filter switches should be in their out positions.
Set the frequency select switches controlling the high and low shelving sections, to 150Hz and 12kHz respectively.
Lastly, set the ‘EQ’ switch to the ‘IN’ position (the associated LED will illuminate).
Moving any one or more of the four faders next to their associated frequency select switches to the right of cen-
tre, will result in the chosen frequency being increased in level. Moving the faders to the left of centre will result
in the chosen frequency being attenuated. Operating the frequency select switch in the high section (8kHz to
15kHz shelving) will introduce a subtle change of emphasis of the high frequencies being aected. Operating the
frequency select switch in the upper mid section (3kHz to 9kHz peaking) will introduce a distinct dierence ac-
cording to the frequency selected, since it is now peaking rather than shelving and also due to the characteristics
of the inductor-based topology. Operating the frequency select switch in the ‘lower mid’ section, 250Hz - 2kHz
peaking, will also introduce a distinct dierence according to the frequency selected, again because of its peaking
nature and the use of inductors in this part of the circuit. Operating the frequency select switch in the low section,
80Hz - 150Hz shelving, will introduce an eective change of emphasis to the low frequencies, according to the
switch setting.
Finally, the three shelving ‘low-pass’ and ‘high-pass’ filter sections are employed to introduce a roll-o of either
high frequencies or low frequencies respectively, according to which of the three push buttons are selected in
each section. The high-pass filters are useful for the minimization of extraneous low frequency ‘rumble’ caused,
for example, by someone’s feet moving about near a microphone stand, nearby trac noise, AC systems, etc. Ad-
ditionally, a high-pass filter can be used eectively during recording to reduce the accumulation of low frequency
sounds that can adversely aect a mix. The three high-pass corner frequencies are 25Hz, 50Hz and 100Hz. The
low-pass filters are used to minimize high frequency noise that may cause ‘harshness’ in a vocal, or to tame the
output of a violin or guitar amplifier, etc. Low-pass filtering is often employed on kick and snare drums and bass
guitars, as well as a means of reducing ‘hiss’. The three low-pass filter frequencies on the A-Range® are 9k, 12k and
15k. Filters can also be used in combination for greater eect.
The amount of boost (accentuation) or cut (attenuation) that is applied to the audio signal is entirely depen-
dent on the programme content and it is not our intention to advise on this. Application of equalisation is a very
subjective matter and is best learned by trial and error. The equaliser bypass switch ‘EQ IN’ is a useful facility for
comparing the signal before and after equalisation.
Insert In and Insert Pre
These two switches are very useful when the unit is used as two independent ‘channel strips’. The ‘pre/post’ facil-
ity allows the user to choose at which point an external signal processing device (such as a compressor/limiter) is
inserted into the signal chain and the ‘bypass’ facility makes it possible to compare the unprocessed signal with
the processed signal by the touch of a single button.
The ‘Insert In’ button enables the unbalanced Insert Send and Return points, which are accessible via ¼” jacks on
the rear of the unit. When ‘Pre EQ’ is selected, the ‘Insert’ point is located between the output of the Mic/Line am-
plifier and the input of the equaliser. In ‘post’ mode, the ‘Insert’ point is instead placed after the equaliser section
and before the final output amplifier.
The ability to bypass the Insert makes it easy to compare the signal with and without the external processing
device, with no need to unplug it from the Send and Return jacks on the rear of the unit. Without this function it
would either be necessary to disconnect the external processor, or operate its controls separately. Because it is
still connected (even when bypassed), it is possible adjust the external device (eg: to set the correct level) before
it is switched into the A-Range® signal path.

directive 2002/96/EC (WEEE). This directive seeks to
ensure that waste electric and electronic equipment is
disposed of in an environmentally responsible manner, at
the end of its life cycle. PMI Audio Group takes seriously
its obligations under this directive to take back WEEE-
affected products and, from 13th August 2005, will mark
all such products with the crossed-out wheeled bin
symbol.

cost-neutrally take back WEEE-affected electric and
electronic equipment in this category, from 1st January

to a disposal and recycling companies in the countries
concerned.

electronic equipment will be disposed of by local
authorities' collection systems.

Statement of RoHS Compliance
PMI Audio Group manufactures complete electronic
products which are covered by the European Union’s
“Removal of Hazardous Substances” directive
2002/95/EC (RoHS). This directive seeks to eliminate
toxic substances from the manufacturing process, such
that when equipment is disposed of at the end of its life
cycle, the materials it contains do not contaminate the
environment and pose health risks. Banned substances
are lead, mercury, cadmium, hexavalent chromium,
polybrominated biphenyls (PBB) and poly-brominated
diphenyl ethers (PBDE). Lead is used together with tin in
solder connections to reduce the melting point of solder.
Lead-free solder requires higher soldering temperatures
which in turn places greater thermal stress on
components.
PMI Audio Group takes seriously its obligations under the
RoHS directive and insists that its factories use only
components that are certified RoHS compliant, as well as
lead-free solder. In a very few cases the necessary
components may not yet be available to the world market
but we work continuously to eliminate any such
exceptions at the earliest opportunity. Our printed Circuit
Boards (PCB’s) and all soldered joints have been lead-
free since 2005.
