Introduction
MODEL 1 is a 6 channel professional mixer designed for use in the club environment by professional DJs and producers
but is equally at home in a small studio or as a compact outside broadcast desk that does not require microphone inputs.
It is unique in oering six fully featured input channels plus two stereo returns in an industry standard “10” format and
has many features not currently available on any comparable device, such as Input pre-amplier drive control, hybrid
Filter/swept Bell EQ, Dual Cue system, Mixer and Cue linking system, and a fully balanced “Tascam format DB25”
connector system for easy interfacing to external soundcards.
MODEL 1 is a purely analogue mixer and features technology normally found on the nest classic studio desks, such as
a fully balanced mix buss, zero crossing detecon for seamless Filter roung and high voltage dierenal power rails.
MODEL 1 is also internally fully modular.

Front Panel Overview

Return Section
Descripon
The Return secon is located on the upper le-hand side of the front panel and
consists of two basic stereo channels for use as return inputs from external eects
processors. Connecon to the Return channels is via 4 x 1/4” TRS Jack sockets
mounted on the rear panel, however the Return channels can also be fed from the
DB25 connector DSUB IN 2 - see page 12 for details.
TRIM - Adjusts the level of the return signal. Each Return input pre-amplier is
equipped with a Hard-Limiter circuit and an excess of gain (+28dB) allowing the
return signal to be driven into distoron (as an eect). Turning the Trim control clock-
wise beyond the “0” and into the regain marked “DRIVE” will progressively distort the
signal unl it reaches maximum clipping. See page 9 for more informaon on Drive.
CUE - Routes the pre-level signal to both the Cue A and Cue B monitor systems.
Return Meters - Provides a visual indicaon of each Return signal level. The Peak (PK)
LED will illuminate at signal levels above +8dBu. This is set lower than on the main
channels due to the xed Drive circuit - note that signal levels above PK will acvate
the distoron circuits.
LEVEL - A rotary fader to adjust the amount of the Return signal fed into the main Mix.
RETURN 1-2 LOW CUT - Acvates a lter that aenuates the low frequency response
on both Return 1 and Return 2. The lter has a slope of 6dB per octave and is set at
320Hz (-3dB).
RETURN 1-2 TO MASTER FILTER - This routes both Return 1 and Return 2 to the
Master Filter secon. This switch is controlled by the zero-crossing detecon system
so can be used as a performance eect.

Master Filter
Descripon
The Master Filter secon consists of a High-Pass Filter (HPF), a Low-Pass Filter (LPF),
and a Resonance control (RES) to adjust the sharpness of the High-Pass lter. Unlike a
Voltage-Control Filter system, (VCF) the lter elements are passive in order to
minimise distoron and eliminate DC voltage breakthrough and because the lter is
passive there is also zero thermal frequency dri. The Master Filter can be used as a
swept frequency performance eect, or as pre-set frequency mix tool to instantly cut
the low or high frequencies of any channel routed to the Filter.
HPF RES - Adjusts the sharpness (Q) of the High-Pass Filter. Set to minimum the HPF
will have a smooth roll o with a low Q. Turning the control clockwise will
progressively increase the Q of the HPF and the gain at the cut-o point - see graph
below for illustraon. Because high Q levels at low frequency can damage the PA
system, high Q sengs are automacally reduced as the HPF control is turned counter
clockwise.
LPF - Progressively aenuates the high frequency content as it is rotated counter
clockwise. A virtually at frequency response up to about 20kHz is achieved with the
control fully clockwise. With the control set fully counter clockwise all frequencies
above 500Hz will be progressively aenuated. The Q of this lter is xed and is not
eected by the resonance control.
HPF - Progressively aenuates the low frequency content as it is rotated clockwise.
A at frequency response down to 30Hz is achieved with the control fully counter
clockwise. With the control set fully clockwise all frequencies below 1kHz will be
aenuated. The Q of this lter is adjusted by the Resonance control.
MASTER FILTER ON - Turns the Master Filter ON. This switch is controlled by the zero-
crossing detecon system so can be used as a performance eect. The zero crossing
system minimises audible clicks and switching arfacts when roung channels to the
Master Filter or switching the lter ON.

Main Channel strip
Descripon
MODEL1 has six idencal main channel strips, each equipped with 2 auxiliary sends,
Input drive control, a unique hybrid EQ lter system, Dual Cues, and a high quality
60mm twin rail fader. The input to each channel is via an RCA connector on the rear
panel, or via the fully balanced DB25 system (see page 12). Channels 3, 4, and 5, are
also equipped with an RIAA pre-amplier for use with turntables.
AUX Sends - The two AUX controls send the channel signal to the Auxiliary mix output
jack sockets (and the DB25 Out) for use with external eects processors or, in some
applicaons, local monitors. The PRE FADE switch selects whether AUX 1 sources its
signal Pre or Post the channel fader; default is post fader, (switch up posion). AUX 2
is always post fader, though there is an internal opon to allow AUX 2 to be switched
Pre or Post fader along with AUX 1.
LINE/PHONO/DSUB - This switch selects which input connector the channel signal is
sourced from. The default (switch up posion) sources the signal from its associated
RCA connector on the rear panel. Pressing the switch routes the signal from the DSUB
(DB25) connector system - see page 12. Channels 3, 4, and 5 can be congured for
use with turntables (Phono) by selecng the small red buon on the rear panel,
situated below its associated earth binding post. If this buon is pressed the LINE/
PHONO/DSUB switch cap will glow red, (only in the up posion), to indicate that this
channel has been congured as a turntable input.
DRIVE - This unique control varies the maximum signal level the channel input pre-
amplier can pass (headroom) before it is driven into clipping (distoron). With the
control fully counter clock-wise the channel headroom is unaected, and signal levels
of > +20dBu will remain clean. As the drive control is rotated clockwise input
headroom is progressively reduced, unl at maximum rotaon the pre-amplier will
start to clip at signal levels above –4dBu. The sha of the drive control is illuminated
and will light red to give a visual indicaon of the clip funcon. See page 9 for more
informaon on the drive control.
CONTOUR/SCULPT - Unique Hybrid EQ. See page 6 for details.
FILTER - This switch routes the channel signal through to the Master Filter secon, see
page 4 for more informaon on the Master Filter. This switch is controlled by the zero
-crossing detecon system so can be used as a performance eect.
CUE A, CUE B - MODEL 1 is equipped with two independent Cue systems, CUE A and
CUE B. CUE A sends the channel pre-fader, post-EQ, signal to the right headphone
monitor secon, and CUE B to the le headphone monitor. Both Cue systems have an
auto-cancel feature, where selecng one Cue will automacally cancel the previous
selecon.
VCA FADER - The 60mm fader controls the DC level for the channel VCA (voltage
control amplier). These twin rail faders have been carefully chosen to ensure long life
and smooth operaon, and feature a heavy feel for greater precision.
5
Contour and Sculpt
Descripon
MODEL 1 provides a unique alternave to the standard type of xed frequency EQ,
which we feel oers greater creavity and the ability to perform smoother mixes.
Whereas a standard EQ has three or four controls providing cut or boost at a xed
frequency, MODEL 1 ulises a combinaon of high and low pass lters plus a wide
frequency range, swept equaliser, with asymmetric cut and boost.
CONTOUR - As the name implies these two controls allow you to “contour” the
frequency range of the audio signal. They consist of low Q, High-Pass and Low-Pass
lters designed not to add colour to the sound as they are swept across their
frequency range. Due to the low Q , these lters only cut, they do not boost, and are
shown in the posion to a give a frequency response.
The two graphs below illustrate how the frequency response is gently rolled o as
these controls are operated, and show the high degree of out-of-band aenuaon
they oer, cung the high or low frequency content of the audio signal.
SCULPT - “SCULPT” is a semi-parametric swept bell lter, and consist of two controls,
FREQ which sets the centre frequency and CUT/BOOST which adjusts the gain or
aenuaon at this frequency. The level of cut/boost is asymmetric; maximum boost
is limited to +8dB, while the cut is extended to -20dB.
Sculpt has a wide Q and a frequency range that covers almost seven octaves.
The Boost/Cut control is detented in the centre 0 posion to indicate a at frequency
response. The FREQ control isn’t detented and can be swept smoothly across its
range.

Master Section
Descripon
The Master secon includes the two Mix level controls, the Master EQ, main buss
metering, record output and the Booth monitor secon.
RECORD OUT - 3.5mm TRS Jack socket feeds the post Master EQ signal as a pre-
fader record output. Nominal level is –6dBu.
LEFT/RIGHT - Two, ten point peak reading LED meters provide visual indicaon of the
mix buss level. Although MODEL 1 has a considerable 28dB of headroom and is
unlikely to suer from clipping due to high signal levels, it is recommended to keep
the average signal level between 0 and +6. Occasional peaks to +9 is acceptable but
operaon with the PK LED ON is best avoided due to the possibility of damaging any
connected PA systems or clipping soundcards, record devices etc.
Play into the red and orange but avoid operang in the white!
MASTER 1, 2 - These controls set the output level for the two main mix outputs.
Master 1 controls the XLR outputs and Master 2 the TRS outputs.
MASTER EQ - Three-Band asymmetric EQ aects all mix outputs, including Booth and
Record. The EQ ON switch is controlled by zero-crossing detecon circuitry which
allows it to be used as a performance eect, as well as a frequency correcon tool.
The response of the Master EQ is shown below.
BOOTH - This secon controls the level and frequency response of the Booth
outputs. The Booth secon incorporates a 2-Band equaliser allowing the user to adjust
the frequency response of the Booth monitors to suit their own preference.
This graph shows the response of the Booth EQ.

Headphone Cue system
Descripon
MODEL 1 has two independent Cue systems, A and B. Cue A routes to the right hand
side headphone monitor and the Cue B routes to the le hand headphone monitor.
The dual Cue system makes it much easier for two DJs to perform on the mixer
together as each can select a separate channel to monitor without interfering with the
other performer’s monitoring. This dual system also allows for Cue interacon
between two mixers linked together. See page 13 for details of mixer linking.
Each headphone monitor is equipped with both 1/4” and 3.5mm TRS jack sockets.
CUE A has an auto-cancel funcon, meaning that selecng one channel Cue will
automacally turn o the previous selecon.
CUE B does not auto-cancel, meaning that each channel Cue operates independently
of the other Cue switches.
SPLIT CUE/SOURCE - Split Cue works in conjuncon with the Source control. When
the Split Cue switch is up the Source Control adjusts the level balance between the
Cue and Mix Busses. When the switch is pressed down the Source control pans
between the Cue signal in the le earphone and the Mix signal in the right earphone.
Level - Sets the headphone volume level.
Warning - The headphone ampliers are capable of driving sensive headphones to
very high sound pressure levels (SPL) which could result in permanent hearing
damage!
