The DX1 is a compact and powerful DSP based audio-processing unit
ideally suited for live applications and fixed installations. To achieve this
the DX1 has 2 inputs and 6 outputs, which can be configured in 5 basic
modes, 2 x 2 way, 2 x 3 way, 4 way, 5 way and 6 way crossover. Each
input has adjustable gain and delay, each output consists of a high and
lowpass filter, 5 bands of parametric equalisation, limiter, delay (adjustable
in 2.6ms steps), gain and polarity controls. RS232 interface and user
memories are provided as well as a multi-level security 'lock-out' function
for all controls. The DX1 is supplied pre loaded with the most common
configurations for all of our current product ranges that require or benefit
from the use of a system controller. Factory presets can easily be updated
by downloading the current file via a PC. The DX1 can also be used as a
fully configurable electronic crossover system incorporating all of the
features listed below.
Features
• Superb audio quality: Carefully optimised Double Precision processing
plus 40 bit internal data path for exceptional dynamic range and sonic
quality.
• A flexible 2 input, 6 output multi-mode format featuring a choice of 2 x 2
way, 2 x 3 way, 4 + 2 way, 5 + 1 way and 6 way crossover modes with
limiters.
• Each parametric section provides +15dB to -30dB of gain at centre
frequencies between 20Hz - 20kHz with a wide range of Qs from 0.4 to
128. All parameters feature fine resolution with 1/36th octave frequency
steps, 0.1dB gain increments and 100 Q settings. Any parametric
section can be set for LF & HF shelving response.
• Six high performance limiters are provided, featuring a wide range of
control over Attack, Release and Threshold parameters. The output
meters show headroom to the limit threshold. The meter time constants
track the limiter time constants to show precise power usage.
• Variable High and Low pass filters for each output can be set for 12, 18
and 24dB per octave slopes with a choice of Bessel, Butterworth or
Linkwitz-Riley responses. Independent control over High & Lowpass
functions allows asymmetric crossover functions to be realised.
• Three velocity-sensitive rotary encoders provide a familiar and easy to
use control format with all filter information displayed simultaneously on
a backlit LCD display.
• Delay of up to 650mS can be independently set for each output with a
minimum increment of 2.6µs.
• Comprehensive standard specification includes a maximum of 80 factory
presets, 19 user memories, RS232 interface for factory preset updates
via a PC and a multi-level security lockout function.
• The DX1 provides exceptional audio quality with a full >110dB dynamic
range, high sampling rate and minimal filtering.
