TLX LIVERPOOL SERIES

Quick Start Guide

Welcome

Thank you for choosing a Turbosound loudspeaker product for your application. If you would like further information about this or any other product, please visit our

website at turbosound.com.

Unpacking the Loudspeaker

After unpacking the unit, please check carefully for damage. If damage is found, please notify your supplier at once. You, the consignee, must instigate any claim.

Please retain all packaging in case of future return shipment.

System Requirements

TLX43 and TLX84 are bi-amp 2-way loudspeakers. Operation (full range or with a subwoofer) requires 2 amplifier channels and 2 controller channels, one for low

frequencies and one for high frequencies. The input signal is divided between the low frequency and high frequency driver in the controller and the individual

amplified signals are fed to the speaker input. Typically 4 loudspeakers can be run from 2 amplifier channels by wiring speakers in parallel.
TLX212L and TLX215L subwoofers require 1 amplifier channel and 1 controller channel. The required filters and conditioning is applied to the signal in the controller

and the individual amplified signals are fed to the speaker input.
Correct controller settings for operation of all models and subwoofers can be downloaded from turbosound.com, and are also available as presets for the Lake LM

series controllers and Lab Gruppen DSP amplifiers.
To avoid wasting amplifier power, you should use heavy-duty speaker cable with a minimum wire size of 2.5 mm² (14 AWG), and preferably 4 mm² (12 AWG) for longer

runs or where total cabinet input impedance is less than 8 ohms. For extreme cable lengths, be aware of cable impedance and resistive losses.

Always observe the correct polarity.

Amplifier Considerations

LIVERPOOL series loudspeakers are optimized for use with Lake LM series controllers and Lab Gruppen amplifiers or Lab Gruppen DSP amplifiers with

Lake processing. A full range of DSP presets to suit a variety of configurations is provided for download on the Turbosound website where limiters, crossover points,

corrective component time alignment and equalisation are pre-programmed to ensure optimum sound quality and long-term reliability. Use Lab Gruppen ‘CAFE’

software - available for download from labgruppen.com - to determine the optimum amplifier configuration for your system. Parameters for the use of third party

amplification and processing can be provided upon request.
LIVERPOOL series loudspeaker enclosures should be driven by high quality power amplifiers designed for true professional use. The use of under powered

amplifiers must be avoided as heavily clipped signals can cause permanent loudspeaker damage. For subwoofers, passive loudspeakers and low frequency, mid

frequency sections of multi-way active loudspeakers, amplifiers should be capable of delivering power equal to twice the continuous power rating at the stated

nominal impedance. For the high frequency section of multi-way active loudspeakers, amplifiers should be capable of delivering power equal to ten times the

continuous power rating at the stated nominal impedance.

NOTE:

Power 1x TLX215L or 2x TLX212L subwoofers per amplifier channel (4 ohm load).

NOTE:

Since TLX subwoofers are wired 1+/- = LF1||LF2; 2+/- = LINK, in order to power multiple TLX212L or TLX215L enclosures, it is advised to construct SUB LINK

cables wired: 2+ -> 1+ and 2- -> 1- . A single NL4 cable from Lab Gruppen bi-wired NL4 outputs (Channel 1 = 1+/-; Channel 2 = 2+/- or Channel 3 = 1+/-;

Channel 4 = 2+/-) connects to the first TLX215L subwoofer then the SUB LINK cable jumps to the second TLX215L subwoofer, providing one TLX215L subwoofer per

amplifier channel. For TLX212L, standard NL4 link cables can be used in conjunction with SUB LINK cables to power two TLX212L subwoofers per amplifier channel.

Refer to wiring diagrams below for further details.
