[. . . ] Refer servicing to qualified service personnel. WARNING: To prevent electrical shock or fire hazard, do not expose this appliance to rain or moisture. Before using this appliance, read the operating guide for further warnings. Este símbolo tiene el propósito, de alertar al usuario de la presencia de "(voltaje) peligroso" sin aislamiento dentro de la caja del producto y que puede tener una magnitud suficiente como para constituir riesgo de descarga eléctrica. Este símbolo tiene el propósito de alertar al usario de la presencia de instruccones importantes sobre la operación y mantenimiento en la información que viene con el producto. [. . . ] The adjacent red LED (11) indicates activation of the built-in DDTTM compression should the system approach maximum power output. See number (11) below for more details on DDT compression. KOSMOS (7) The KOSMOS feature is a low-frequency reinforcement and stereo imaging enhancement system that augments the input signal by generating bass notes one octave below (QuakeTM function) the original, and allowing the stereo image to be widened (Xpanse® function). This patented enhancement is also available as a separate processor unit. The Quake Sub Level knob (7a) sets the powered subwoofer output and simultaneously sets the amount of KOSMOS Quake function. The Xpanse knob (7b) controls the amount of high frequency expansion applied to the high-pass outputs (8) and the speaker level outputs (9). The bypass switch (7c) bypasses the KOSMOS entirely. When in bypass mode, the Quake Sub Level knob sets the powered subwoofer level without any KOSMOS effect. The adjacent, blue LED (7d) illuminates when the Quake function is active. High-Pass Output (8) These left and right, line-level, high-pass frequency outputs track with the level of the Master System Level control (6). These pole stands should not be extended beyond 65" in height or carry more than 20 lbs. each in weight. Sending Audio Signal to the TriFlex There are a variety of ways to provide audio signals to the TriFlex. The balanced line-level input(s) allow the use of an XLR plug or a 1/4" phone plug: either a standard, single-ended TS (tip/sleeve) plug or a balanced TRS (tip/ring/sleeve) type 1/4" phone plug. It is not advisable to connect cables to the jacks while the unit is ON and the volume is turned up. The output level tracks the Master System level control on the TriFlex. The nominal polarity of these outputs is positive (pin 2) and can be run directly into most full-range, powered speaker systems, or to a conventional power amp and a separate speaker system. If you experience hum or related ground loop problems, it might help to lift the shield ground on the balanced XLR cable at the TriFlex end. This can be accomplished via the convenient ground lift switch (10b) located underneath the High-pass output jack group. Always turn the volume control down before plugging and unplugging cables or switching ground lift switches. Left & Right Outputs These outputs will supply a full-range, 8 Ohm minimum speaker system with a high-pass frequency amplifier signal when using the TriFlex with speakers other than the TriFlex satellite speakers. The Xpanse control (7b) will expand the stereo sound stage and add high frequency processing to these outputs. TriFlex as a Subwoofer Only (Add-On Use) When using the TriFlex as a powered subwoofer only, connect a full-range stereo signal to the inputs (5) or plug a mono signal into the left input (5a) and engage the Mono switch (5d). The subwoofer will reproduce frequencies from approximately 45 Hz to120 Hz. TriFlex: Subwoofer with Built-in Crossover To fully utilize the built-in crossover, a line-level, high-pass signal is available at the high-pass output jacks (8). Use the left output to send the high-pass output to a powered, full-range speaker or to a power amp and full-range speaker. The full-range speakers will reproduce frequencies from 120 Hz and up. This can be repeated if multiple TriFlex units are used in a larger interconnected system. Connecting Multiple Triflex Systems The TriFlex is designed with multiple parallel inputs that allow daisy-chaining from one TriFlex system to another. Connect the first cable from the mixer output to the first TriFlex. [. . . ] The unit, in use, is subject to a great deal of vibration that may cause the screws to loosen over time. 10 GROUND GND LIFT KOSMOS HI PASS LEFT RIGHT OFF +10 OFF MAX OFF MAX ON BYPASS POWER LEFT INPUT STEREO MONO LEFT THRU INPUTS INPUT LEVEL EXPANSE QUAKE STEREO MONO GROUND GND LIFT RIGHT INPUT RIGHT THRU LEFT OUT RIGHT OUT TO LEFT SATELLITE TO RIGHT SATELLITE BYPASS BYPASS TriFlexTM Block Diagram of Signal Flow 11 POWER AMPS INTERNAL WOOFER POWER ON OFF FUSE FREQUENCY RESPONSE CURVE 120 Amplitude Response (1W 1m On-Axis) 110 dB SPL (re 20 Pa) 100 90 80 70 20 50 100 200 Frequency (Hz) 500 1k 2k 5k 10k 20k 12 TriFlex TM Powered Subwoofer and Stereo Satellite System SPECIFICATIONS Enclosure TriFlex (domestic) Frequency Response 45 Hz to 120 Hz Usable Power Amplifier (at 120 VAC line) Subwoofer section alone 1500 Watts peak dynamic power, bridged mode 1000 Watts coninuous at less than 0. 3% distortion L & R Output section alone 750 Watts peak dynamic power either channel All channels loaded full Subwoofer section 750 Watts peak dynamic power 500 Watts continuous L & R output section 375 Watts peak dynamic power either channel 250 Watts continuous Nominal Sensitivity (1W at 1M, swept sine input in anechoic environment) 95 dB Maximum Sound Pressure Level 128 dB peak Transducer Complement 1508-8 HPS 15" Low RiderTM Bass woofer Box Tuning Frequency (FBox) 40 Hz Electronic Crossover Frequency 120 Hz Crossover Type Internal electronic two-way crossover with bass boost and 24 dB/octave subsonic filtering with active soft-knee limiter on levelcontrolled low pass.
