TDX 1

Digital System Controller

The Tannoy TDX1 is a ‘2 in 4 out’, powerful, digital system controller, which features
Crossover, EQ, Delay and Limiting functions. The superior audio quality of this
feature packed unit offers installers and contractors a competitively priced, yet highly
versatile solution for flexible system configuration and optimizing the performance
of Tannoy loudspeaker systems.

XLR INPUT / OUTPUT

Ideally suited to fixed installations and live applications, the TDX1 combines the
functions of multiple conventional products in a compact 1U of rack space. For ease
of use, presets for the most common configurations of the Tannoy product ranges
are preloaded in to the TDX1. A further 100 user presets are provided allowing other
custom configurations to be programmed.

Each input has gain control and 4 bands of parametric EQ with band 1 and 4 offering
settings for LF and HF shelving response. The unique routing engine will allow any
input to be sent to any output. Butterworth, Bessel and Linkwitz Riley type filters are
available on all outputs, which can be configured as 2, 3 or 4-way crossovers. All
output channels feature an independent speaker alignment delay (200 ms per
channel) and a 4 band parametric EQ for speaker management. Four high performance
limiters offer a wide range of control over Attack, Release and Threshold parameters.
The two Input and four output connections are via balanced XLR sockets. A SPDIF
digital input (44.1 or 48kHz) is also provided, allowing the signal to be kept in the
digital domain.

Set up of the unit is exceptionally simple thanks to the intuitive signal flow based
interface. Programme settings are clearly displayed on the 2 x 16 character backlit
LCD. The function buttons and input level meters are also backlit, therefore allowing
ease of use even in subdued lighting conditions.
