4.2 Damping Factor in cable Turbosound recommends that for large scale PA use the total system damping factor should be 15 or greater. Longer cables will reduce the overall damping factor of the system. In order to keep the damping factor over 15 it will be necessary to increase the impedance of the load to keep the damping factor.
user manual Flashline 5. System Configurations 5.1 Suggested amplifier loading for the TFS-900H Each amplifier powers three enclosures. Whilst in theory the amplifier can power four enclosures this presents the bass and low-mid with a 2 ohm load, which does not offer optimum performance. BASS loading 2.6 ohms LOW loading 2.6 ohms MID loading 4 ohms...
user manual Flashline 5.2 Suggested amplifier loading for subwoofers Each amplifier powers up to six TFS-900B or TFS-900L enclosures. Each NL4 connector can power three subwoofers. Each subwoofer has a drive unit wired to each pair of pins on the NL4 connectors. Do not use the NL4 and NL8 connections simultaneously on one amplifier.
user manual Flashline 5.3 Suggested amplifier loading for subwoofers in cardioid mode Each amplifier powers four TFS-900L or TFS-900B enclosures. The first NL4 on each amplifier powers the rear facing cardioid unit, while the second NL4 powers the three forward facing units. Do not use the NL4 and NL8 connections simultaneously on one amplifier.
user manual Flashline 5.4 Suggested amplifier loading for a 4-way Flex Array system Each amplifier powers three Flex Array TFA-600H cabinets and two TSW-218 subwoofers.

user manual Flashline In-rush current is controlled and limited during the soft-start sequence. This enables multiple amplifiers on the same AC mains circuit to be turned on simultaneously. 9.6 Grounding Analog inputs feature Iso-Float™ ground isolation, a technology which combines the benefits of transformer- coupled isolation with the advantages of clean, direct-coupled inputs. The audio converters are galvanically isolated, and not connected to the main ground. High-speed transformers and opto-isolators create a barrier between the device and the outside electrical environment.

user manual Flashline 11. Signal Flow and Lake Processing 11.1 Signal Flow Figure 5-1 and Figure 5-2 depict the audio signal flow inside a 20000DP. It is worth noting that this sophisticated device provides seven points in the signal chain where the signal level can be adjusted, muted or disconnected. Important information regarding correct setting of the gain structure can be found in the 20000DP Operation Manual.
user manual Flashline If the required audio signal is not passing correctly, verify the connection, mute and volume settings at all seven stages. 11.3 Power Output Section: Limiting and Sensitivity The Current Peak Limiter (CPL) dynamically limits the drive to the power stage based on three parameters: sensed output current level, feedback from the output stage, and sensed voltage clip from the ISVPL. This ensures that power output is maintained within the design limits of the amplifier.
user manual Flashline Electrical characteristic data is used to enable load verification (LoadSmart) and monitoring facilities (SpeakerSafe) to be performed on the 20000DP. This data set is termed a Fingerprint. When a 20000DP-specific loudspeaker type is loaded, its Fingerprint load characteristics are included. These load characteristics are stored in a file with a “.mdl” suffix and are loaded simultaneously with the module file.
Page 45
user manual Flashline • A Module file is the smallest set of data that can be stored and recalled; it contains crossover, gain, delay, and limiter information for an individual loudspeaker. A Module file may be recalled into other Lake devices. It is not possible to store a Module File directly on the hardware device.
