12 TFM Series Quick Start Guide 13

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

The TFM122M and TFM152M models are switchable passive / bi-amp 2-way loudspeakers.

Passive operation (full range or with a subwoofer) requires 1 amplier channel and 1 controller channel. The input signal is divided between the low-frequency and

high-frequency drivers internally with a passive crossover. Bi-amp operation (full range or with a subwoofer) requires 2 amplier channels and 2 controller channels,

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

amplied signals are fed to the speaker input.

Correct controller settings for all models operation and subwoofers can be downloaded from turbosound.com, and are also available as presents for Lab Gruppen

ampliers, and for LAKE LM processors. To avoid wasting amplier power, you should use heavy-duty speaker cable with a minimum wire size of 1.5 mm (16 AWG),

and preferably 2.5 mm (14 AWG) for longer runs. For extreme cable lengths, be aware of cable impedance and resistive losses. Always observe the correct polarity.

Amplier Considerations

The TFM series loudspeakers are optimized for use with the Lab Gruppen PLM+ series ampliers or LAKE LM series controllers used in combination with Lab

Gruppen FP ampliers. A full range of DSP settings to suit any conguration are provided for download on the Turbosound website. The use of third party

amplication and processing is only advised using the matrix of manual settings as well as the limiter calculator provided on the Turbosound website. TFM

series loudspeaker enclosures should be driven by high quality power ampliers designed for true professional use. Power ampliers should be capable

of delivering long term broadband power equal to half the loudspeaker’s peak power rating at its stated nominal impedance. The use of underpowered

ampliers must be avoided as heavily clipped signals can cause permanent loudspeaker damage. Limiters, crossovers and equalisation points must be

set in accordance with the settings provided on the Turbosound website. This will ensure the optimum sound quality and long-term reliability as well as

protection from damage.

Neutrik speakON NL4 locking input connector(s) are provided, allowing options for input and link, passive, and bi-amp operation.
