Introduction
Overview
Introduction
PURE DRIVE QUAD takes the highly regarded PureDrive™ mic preamps from the SSL ORIGIN console and delivers them in a 4
channel 2U rackmount device, supercharged with cutting-edge conversion and flexible digital connectivity.
3 Flavours, 1 Mic Pre
Each of the 4 preamps offers a choice of three modes: Clean, Classic Drive and Asymmetric Drive. Clean is a linear, ultra-low noise
preamp capable of impeccably recreating the sound source with clarity and detail. Classic Drive introduces pleasing harmonic
distortion to enrich the input signal, using predominantly odd harmonics; the same sound signature found on the ORIGIN console.
Asymmetric Drive offers up a new colouration option, making the even harmonic content dominant and providing more pronounced
thickness, colouration and softening of transients.
Analogue Obsession
PURE DRIVE QUAD continues SSL’s obsession for progressive analogue circuit design with high performance mic preamps,
evolved from SSL's acclaimed VHD™ (Variable Harmonic Drive)* technology. In addition, PURE DRIVE QUAD features balanced
analogue outputs/insert sends for external processing, as well as high headroom insert returns/ADC inputs with +24 dBu A/D
line-up level. No electro-mechanical components such as potentiometers, mechanical switches or relays are used in the critical
audio signal path which increases product longevity and results in impeccable level matching across all channels. The use of
digitally controlled analogue circuits, along with by stepped pots and electronic switches further simplifies recall and precision of
settings.
Extensive Connectivity
PURE DRIVE QUAD features extensive connectivity, opening up a world of possibilities; whether you're tracking a band in a world-
class recording studio, looking to expand your home studio setup or even going out on tour, PURE DRIVE has you covered with an
array of options to best suit your needs. It can also be used to add analogue warmth to stems by running DAW stems through it,
using the line-level inputs. Furthermore, an integrated USB audio interface allows you to record directly into your DAW, via cutting-
edge 32-bit/192 kHz conversion. Or, use the AES and ADAT outputs to connect to your existing audio interface. The AES and ADAT
outputs can also be individually re-purposed to be fed from the on-board USB audio interface (as outputs from your DAW). To round
out the digital side of things, there is an auto-ranging word clock input and output for robust digital clocking.
VHD™ (Variable Harmonic Drive) was introduced in the SuperAnalogue™ Duality large-format console in 2006,
featuring an innovative FET-based circuit that provides a range of colouration options from 'valve warmth' to
'transistor grit'.

Tutorial
INSERT LED
Lights green to indicate the insert return is active. To enable/disable the insert return, push the GAIN control. Inserts are a great way
of incorporating external processing (such as an EQ or compressor) into the signal path ahead of the analogue to digital converter
(ADC). Alternatively, you can use the insert return as a way of bypassing the preamp stage, which can be useful when using signal
from external preamps or whenever straight-forward, pristine analogue-to-digital conversion is needed.
Useful Info: Insert returns are channels 1-4 of the rear panel D-Sub connector.
POLARITY (Ø LED)
Lights green to indicate the polarity is flipped. To enable/disable polarity flip, push the TRIM control. When dealing with multi-mic'd
instruments such as drums, phase cancellations can occur due to the microphones receiving the sound waves at different times.
Flipping the polarity (or phase as is often referred to) on certain channels can help resolve these cancellations.
Top Tip - It is common practice to flip either the top or bottom snare microphone to ensure a 'fatter' sound.
+48V
Lights red when enabled. Provides +48V phantom power, required for certain condenser and active ribbon microphones. Dynamic
or Passive Ribbon microphones do not require phantom power to operate and in some cases can cause damage to the microphone.
If in doubt, make sure +48V is disabled before plugging in any microphone. When engaging/disengaging +48V, the button will blink
for 4 seconds to signify the audio is being temporarily muted in order to avoid any unwanted clicks/pops.
LINE
Lights bright white when active. Activating the LINE button switches the input to line mode, which sources the signal from either
the rear panel TRS jack or the dedicated D-Sub connector. The connectors are hardwired in parallel so it is recommended to only
use one at a time. In LINE mode, +48V and ZΩ buttons are disabled and the impedance is fixed at 22kΩ.
ZΩ
Changing the impedance allows you to correctly load match some vintage microphones, or even change the tonality of the input
signal, giving further creative control when recording. Press the ZΩ button to cycle through input impedance options. Press and
hold ZΩ to go backwards through the selections.
Green = 12kΩ Dim White = 1.2kΩ Amber = 600Ω Red = 400Ω
Generally speaking, for condenser and active microphone altering the microphone impedance will not make a difference to
the sound, in which case leaving the preamps set to factory default Green (12kΩ) is recommended. For ribbon and dynamic
microphones, impedance affects the inherent tone of the individual microphone and therefore can be used as powerful tone
shaping tool, almost like an EQ. This works on the principle of the microphone's output impedance as a function of frequency not
being constant.
• Selecting a high input impedance will give less deviation from the natural response of the microphone, resulting in a more
balanced and natural-sounding frequency response. A general rule of thumb is that the preamp should have an input
impedance of at least ten times the output impedance of the microphone.
• A lower input impedance will give a more accentuated response from the microphone, enhancing the timbre and signature
of each individual mic. Frequencies at which the microphone’s output impedance is higher than average will be attenuated,
while frequencies where the microphone’s output impedance is lower will be boosted.
• Changing from a high input impedance setting to a low input impedance setting will result in a slight drop in level. This is
normal and is a result of the greater ratio between the microphone’s output impedance and the preamp’s input impedance.

Tutorial
DRIVE [TYPE]
Toggles between the 3 different microphone preamp modes: Clean, Classic Drive and Asymmetric Drive.
Clean (backlit) - linear, ultra-low noise and distortion preamp capable of impeccably amplifying the sound source with clarity and
detail.
Classic Drive (amber) - introduces harmonic distortion to enrich the input signal, using predominantly odd harmonics; the same
drive sound found on the ORIGIN console. The harmonic distortion is level/gain dependent.
Asymmetric Drive (green) - an alternative to Classic Drive mode, where the even harmonic content becomes dominant than the odd
harmonics. Results in a more pronounced thickness and softening of transients. The harmonic distortion is level/gain dependent.
To engage Asymmetric drive mode press and hold the DRIVE button for a second or so.
Top Tip - The DRIVE button flashes red to indicate you are clipping the main preamp or the trim
stage. Lower the GAIN (or TRIM) to correct.
Classic Drive vs Asymmetric Drive
The graph below shows the difference between the harmonics generated by Classic Drive vs Asymmetric Drive at a nominal 29
dB of gain.
• The blue harmonics are from the Classic Drive setting, whereas the Red harmonics are from the Asymmetric Drive mode.
• Note that the 2nd harmonic is much more prominent in Asymmetric Drive.

Hi-Z/DI - Instrument Inputs
Each of the input channels feature a 1MΩ Hi-Z/DI unbalanced Instrument input for connecting sources such
as guitars and keyboards.
These inputs have automatic detection meaning that plugging a jack into the socket will automatically cause the
Hi-Z/DI Input to be the selected source (instead of Mic or Line). The +48V, LINE and ZΩ buttons are disabled
but you can of course still use the DRIVE modes to colour the signal (or not) as you please.

Please note that when the unit is connected via USB, the front panel RAT E and CLK buttons become inactive.
Use your host computer to make adjustments to the Sample Rate and Clock Source. For more information on the built-in USB audio
interface, refer to the USB audio interface section of this user guide.
Important information - Clocking to Wordclock or ADAT whilst using USB on Mac
If PURE DRIVE is connected to your host computer via USB and you want to clock to an external source (wordclock or ADAT), you
must first set the Internal Clock rate of PURE DRIVE to match the external clock rate, and then change the clock selection from
internal to Wordclock In or ADAT.
Remember, when you are connected via USB, clock source switching must be done from AudioMIDI setup on your Mac, as the
RAT E and CLK front panel buttons are disabled on PURE DRIVE.
If the internal clock rate of PURE DRIVE does not match the external clock rate when the clock source is changed to external,
then it will show up with No Valid Formats in Audio MIDI Setup on your Mac. To recover from this state, you must switch back to
Internal clock.
It is also important to note that if you want to change the sample rate of the external clock, you must first set PURE DRIVE back to
Internal clock, change the external clock rate as desired, then change PURE DRIVE to match the new rate of the external clock,
before finally switching PURE DRIVE back to Wordclock In or ADAT.

Rear Panel Connections
Mic/Line Analogue Inputs
The rear panel Combo-XLRs provide access to the analogue microphone-level inputs (via the XLR or line-level inputs via TRS jack).
Use the LINE buttons on the front panel to switch between the two options. Alternatively, use the dedicated Line Inputs available
on the D-Sub (DB25) connector.
Analogue Outputs / Insert Sends
The rear panel female XLRs provide access to the balanced analogue outputs, which can also serve the purpose of acting as insert
sends for connection to external processing devices.
Insert Returns & Line Inputs
The rear panel D-Sub connector provides access to the insert returns and dedicated line-level inputs. You may find it more
convenient to connect line inputs via this connector, to remove the need for unplugging/replugging the Combo-XLRs. D-Sub to
Female XLR breakout looms should be used to access these connections.
TRS and DB25 are hardwired in parallel. It is advisable to only use either/or and avoid using both simultaneously.

Re-purposing the Digital Outputs as DAW Outputs
Normally, the digital AES and ADAT outputs are fed from the Analogue to Digital converter. i.e. Analogue inputs are converted to
ADAT and AES. However, it is possible to re-purpose the AES and ADAT outputs (independently) and feed them from the DAW (as
outputs) via USB instead. Please refer to the Settings section of this user guide for the instructions on how to do this.
Normal mode - AES and ADAT Outputs fed from A-D converter DAW feeds digital outputs mode - AES and ADAT
fed from USB. Example given at 44.1/48 kHz
USB audio interface/DAW Outputs
The number of outputs available to the DAW depends on the sample rate you are working at. Also note that even if you configure
the AES/EBU outputs to be fed from the ADC (default setting), if you have enabled the ADAT to be fed from USB the AES/EBU
outputs will still show when connected to the computer, even though no signal is passed to them from USB. This is to keep the
ordering of the output list consistent.

Soak and Potentiometer Test Mode
Soak mode is used to check the correct operation of all lights and indicators on front panel. It cycles through the phases listed
below. To enter Soak mode, hold down Channel 1 +48V and LINE buttons during the power-up sequence.
1. All switches lights bright white, if available (otherwise off) + meters pattern
2. All switches lights red, if available (otherwise dim white) + meters pattern
3. All switches lights green, if available (otherwise dim white) + meters pattern
4. All indicators lit up (green or red, depending on function) + meters pattern
5. Same as 1 but meters full lit
6. Same as 2 but meters full lit
7. Same as 3 but meters full lit
8. Same as 4 but meters full lit
In this mode it’s also possible to test the correct operation of the potentiometers. A position change on any of the pots will trigger
the relay to click as a confirmation feedback.
Channel 1 GAIN controls the speed at which the patterns are cycled.
Full CCW position pauses the animation at the current step. Rotating the knob towards clockwise direction will increase pattern
speed.
Exit Soak and Potentionmeter Test Mode mode by holding the STANDBY button until the unit power cycles back into normal
operation.
