Above each bay of six channel strips, the TFT meter display provides a large range of useful information on a per-
channel basis, including audio and dynamics metering, processing order, bus routing, automation bargraphs (optional)
and Total Recall™ (optional).
At your first introduction to the Duality SE console, you will immediately see that the channel strip controls are
presented in reassuringly familiar manner. The following pages describe each control in detail, with brief coverage of
the routing possibilities. See the start of this section for more on signal routing.
In the following descriptions, the connectors referred to are on the rear of each channel module, unless
stated otherwise.

This provides two external inputs, the first is a line level DAW return (D-connector), the other
(XLR connector), is intended as a mic input but may be used for both mic or line inputs.
Normally the Mic Input feeds the variable gain INPUT amplifier, and the DAW return feeds
a unity gain line amp. However a centrally controlled INPUT FLIP function reverses the
input routing so that the DAW return can be processed by the variable gain amplifier stage
without the necessity for external patching.
The variable gain amplifier features two completely independent preamp stages. Both have
electronically balanced inputs with very different but complementary sonic qualities. The default
preamp uses SSL's acclaimed Super Analogue circuitry to provide an extremely low noise, extended bandwidth front
end with the minimum of signal colouration. Pressing the DRV IN button routes the input signal to a completely
different preamp featuring the SSL-developed VHD™ (Variable Harmonic Drive) circuitry. VHD emulates the
characteristics of a classic valve front end but with the option to tailor the harmonic mix when the preamp is
overdriven by adjusting the DRIVE pot. In conjunction with the 24dB PAD and Hi-Z input impedance option,
VHD can provide subtle valve style warmth to a mic signal or aggressive tonal shaping to existing DAW tracks.
However, be aware that, due to differences in the mic amp topology, exact matching of gains is not possible.
Note that many of the signal routing functions on a channel strip are also available on the central routing
panel, and some are only available on the Central routing panel
The post input stage CH (channel) control provides final ±20dB gain trim (for reducing the level when the input
section is being abused for creative reasons) and polarity inversion (Ø), for the centrally selected channel source.
Available input options are the output of the mic input preamp (MIC), the balanced line level DAW return (LINE),
or the channel’s associated track bus for patch free subgroups (BUS). In the latter case, the channel input is replaced
by the output of one of the 24 Track Mix busses where Bus N feeds the input of Channel N, N+24, N+48 etc.
FILT to INP locks the high and low pass filters to the channel source. +48V phantom power for mic inputs is
selected on the Central Routing Panel.
Note that selecting INPUT FLIP will automatically switch off phantom power in order to prevent
damage to the output stage of connected equipment.
