TQ-445DP

QLIGHT™ SERIES ENGINEERING INFORMATION
The TQ-445DP is a three-way self-powered full
range enclosure incorporating integral amplifiers
and control electronics. The use of DSP amplifier
technology ensures an exact match between
amplifier and speaker for optimum acoustic output,
and offers exceptional ease of use by having the
entire electro-acoustic system in one convenient,
easily transportable physical package.
The TQ-445DP features a new generation of
innovative digital power amplifier modules,
utilising revolutionary 96kHz DSP technology
to give operating efficiency in excess of 90%.
The rear panel carries a fully integrated Class
D amplifier and control electronics module,
which is field removable for servicing.
Providing two independent amplifier channels
each capable of delivering 800 watts rms into
8Ω, this module also incorporates electronic
crossovers, delays and high performance
limiters set to give optimal performance from
the drive units. A Neutrik Powercon connector
provides mains input to the unit – the switch
mode power supply is auto-sensing over a
range from 100 volts to 240 volts – and 3-pin
XLR’s are used for input and parallel link
signal connections.
The TQ-445DP incorporates a customdesigned
co-axial 12”/1” driver in an
optimally tuned vented trapezoidal
enclosure. The critical mid-range frequencies
are handled by a proprietary 6.5” cone
transducer on a 60° by 40° horn, loaded with
a TurboMid™ device. The remaining high
frequencies are effortlessly handled - and
divided from mid-high frequencies by an
integral passive network - by a 1"
compression driver, which is subjected to
minimal mechanical stress. When compared
to conventional designs, the TQ-445DP is
able to offer higher SPL, significantly lower
distortion, and unsurpassed vocal projection
capabilities in an equivalent sized physical
package.
The birch plywood enclosure is fitted with
integral rigging points, kelping brackets and
a standard 35mm pole mount socket,
enabling its use with many different types of
flying hardware. It is finished in black semimatt
textured paint, and includes a steel
mesh / reticulated foam protective grille.
Flush side handles are provided for lifting
and carrying.

Frequency response The frequency response shown was obtained by feeding a swept sine wave through the
system in a half space environment. The position of the microphone was vertically on-axis at a distance of 2
metres, then scaled to represent 1 metre. 2nd & 3rd Harmonic Distortion Distortion measurements were obtained
using an Audio Precision harmonic distortion analysis system and comply with AES recommendations for
enclosure measurement (AES paper ANSI S4-26-1984). Data Conversion All graphs were digitally generated using
the APEX custom software system, designed to translate data derived from Audio Precision ‘System One’ test
equipment into AutoCAD™. This program enables graphical information to be plotted to a high degree of
accuracy.

QLIGHT™ SERIES ENGINEERING INFORMATION
The diagrams below illustrate several different methods of rigging TQ-445DP enclosures. In
most cases the lower kelping bracket is used to set the desired downward inclination of the
cabinet. When using the T-bar, the enclosure may be rigged either using two points or only a
single pick up point. The downward angle will be determined by which attachment hole is
chosen on the crossbow.

(165mm) mid frequency loudspeaker loaded with a TurboMid™ device and a 1” (25mm) high
frequency compression driver mounted co-axially to the low frequency loudspeaker. The integral
power amplifier module shall provide two channels of Class D amplification, crossover, delays,
output limiting and equalisation incorporating frequency responses optimised for speech and
music. Performance specifications of a typical production unit shall be: Frequency response,
measured with swept sine wave input, shall be flat within ±4dB from 55Hz to 20kHz. Nominal
dispersion, at -6dB points, shall average 60°H x 40°V. Maximum SPL (peak) measured with music
program at stated amplifier power shall be 137dB. Dimensions: 588mm x 409mm x 363mm (23.1”
x 16.1” x 14.3”). Weight: 32.5kgs (71.5lbs). The loudspeaker shall be the Turbosound TQ-445DP. No
other loudspeaker shall be acceptable unless submitted data from an independent test laboratory
