TLX LIVERPOOL SERIES
Amplifi er Considerations
LIVERPOOL series loudspeakers are optimized for use with LAKE LM series controllers and LAB GRUPPEN amplifi ers or LAB GRUPPEN DSP amplifi ers with
LAKE processing. A full range of DSP presets to suit a variety of confi gurations 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 amplifi er confi guration for your system. Parameters for the use of third party
amplifi cation and processing can be provided upon request.
LIVERPOOL series loudspeaker enclosures should be driven by high quality power amplifi ers designed for true professional use. The use of under powered
amplifi ers 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, amplifi ers 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, amplifi ers 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 amplifi er 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 fi rst TLX215L subwoofer then the SUB LINK cable jumps to the second TLX215L subwoofer, providing one TLX215L subwoofer per
amplifi er channel. For TLX212L, standard NL4 link cables can be used in conjunction with SUB LINK cables to power two TLX212L subwoofers per amplifi er channel.
Refer to wiring diagrams below for further details.
