Turbosound TCS-081C Manuel utilisateur

The TCS-081C is a compact trapezoidal passive two-

way loudspeaker enclosure designed for use in a

wide range of fixed installations.

It consists of an 8” reflex-loaded low

frequency driver and a 1” high frequency

compression driver on a 100°H x 60°V

Converging Elliptical Waveguide™ in an

optimally tuned trapezoidal enclosure. These

high grade components are matched with an

internal passive crossover to ensure a

seamless transition between the HF and LF

drivers.

The crossover incorporates a two-stage

thermal overload protection system which

prevents damage to the high frequency

driver, reacting instantly to large transient

peaks while still allowing wide dynamic

range to be maintained. Although the

protection system is transparent at normal

operating levels, as the level increases the

signal is gradually and imperceptibly

compressed once the critical threshold has

been reached.

The cabinet is constructed from 12mm (1/2”)

birch plywood, screwed and glued together

for maximum rigidity. A powder-coated

perforated steel mesh grille, backed with

reticulated foam, protects the drive units

from damage.

Rigging points are provided on the top,

bottom, sides and rear of the cabinet to

enable the TCS-081C to be suspended and

angled in permanent installations using M10

shoulder eyebolts. The enclosure is also

fitted with internal rigging points for use

with Turbosound and Omnimount™ wall

and ceiling brackets.

A Neutrik Speakon NL4MP speaker

connector and a four-way barrier strip are

located on the rear panel, providing input

and parallel connections to additional TCS

Compact series cabinets.

The TCS-081C is finished as standard in

durable black or white semi-matt textured

paint; raw wood and custom colour options

are also available for decor matching. A

weather-resistant version is optionally

available with an IP rating of 54, enabling

use outdoors and in humid conditions. Line

transformers are optionally available for use

with 70v or 100v line distributed systems.

Impedance A constant current circuit was used to measure the impedance. 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.
