GEARMODULAR PROCESSING SUPPLEMENT
Cartec Audio
Cartec Audio’s Compere 500-Series enclosure has 8 slots with an
internal power supply providing 3A per rail. It has an assignable
front panel input XLR in addition to the 8 input and output XLRs.
Users can introduce the front panel input signal to any one of the 8
modules via the front panel Aux to the input module rotary switch
and associated 48V phantom power switch. This is intended
to provide uninterrupted phantom power when switching to
dierent preamp modules. The Aux to output module rotary
switch selects which module carries the output and the audio
appears on the dedicated rear mounted routing section output
XLR. The regular module’s XLR I-O audio path is defeated while
the Aux Compere function is activated for that module. At the
rear of the rack each module slot has a link switch that routes
the output of a module into the input of the next module slot
on the right. Cartec manufacturers two 500-Series module. The
PRE-Q5 is a transformer-based preamp
that incorporates a passive inductor
equaliser and a balanced output
attenuator. The circuit is identical to
the larger PRE-Q1A two-channel high-
quality transformer-based microphone
preamplier, but without the High/Low
boost front panel controls. The FE-Q5
is an inductor-based equaliser that
incorporates a discrete amplier stage,
a 12dB/octave HP lter (independent
of equaliser with its own discrete
Op-Amp), and custom-wound input and output transformers,
plus two multitap inductors and two Op-Amps.

Chandler Limited
Chandler’s TG2-500 preamp builds upon the
TG2 preamp/DI, which delivers the sound of
the EMI TG12428 preamp used in EMI/Abbey
Road recording and mastering consoles in
the late 60s and early 70s. Using the identical
TG2 circuit, transistors, and transformers, the
TG2-500 delivers 10-60dB of gain and uses a
coarse gain control and a ne gain control as
found on EMI consoles. The unit provides 300
and 1200Ohm input impedance as on the TG2.
As such, the TG2-500 delivers
frequency response identical
to the TG2 and has the same
high frequency bump and mid
forward tone that users enjoy with the TG2.
The Germ 500 MKII is Chandler’s well-known
Class-A, discrete, transistor Germanium Preamp
adapted for 500-Series racks. It uses the same
transformers and amp blocks to
ensure that it sounds consistent
with the ‘full-size’ rack version
and oers -5dB to +65dB gain
and a transformer-balanced mic
input with 300Ohm impedance.
The 500-Series format Little
Devil Pre Amp’s Class-A gain stage sounds big,
open, and full of life. Just about any parameter
of the sound is changeable, including the
ability to change both the Feedback and Bias
of the amplier. The Feedback control increases
harmonics over the range of the control. Other
features include High and Low input impedance,
transformer-balanced line in for using the unit as a colour box on
mixes or tracks, low cut, and a bright switch.

Empirical Labs
DocDerr is a 500-Series channel strip with six dierent sections
of digitally controlled analogue processing. A low-noise preamp
capable of line or 16dB of instrument gain is followed by four
sections of EQ offering one selectable high pass and three
parametric bands. The dynamics section provides Empirical
Labs compression and a tape emulation circuit to soften high
frequencies and clips. A Mix knob allows the user to blend the
uncompressed EQ signal with the compressed and saturated
signal. Inputs and outputs are DC coupled, and the output can be
switched between single ended or dierential, yielding +/-6dB
of gain.
At the heart of Empirical Labs’ 1U EL500 rack is a super quiet
power supply to ensure optimal performance from any 500-Series
compatible device. Two can be accommodated side by side and
will ush mount. Additionally, a 1/4-inch instrument preamplier/
DI box is integrated into the front panel. To ensure the best
possible enclosure/power supply combo for its own 500-Series
modules, Empirical Labs can preload and bundle its DerrEsser
and DocDerr modules in any mono or stereo combination along
with its EL500 rack.
Empirical Labs
also caters to the
500-Series DIY
community with
its Proto500, a
prototyping system
for the API 500-Series powered rack system. It includes a PCB card,
a metal front panel with mounting positions, and ve switches,
as well as a user manual. With more than 2700 pads and pre-laid
out power supply traces, users can prototype relatively complex
circuits for the 500-Series with relative ease. Front panel graphics
can be pressed or silkscreened on for a professional look to match.
