2.2 Operation- Built-in CrossoversCROSSOVER FILTER SELECTIONThe TA series amplifiers have built-in low-pass andX-OVERhigh-pass crossover filters for bi-amplifying yoursystem. Select " LPF, FULL or HPF" by moving theLPF- FULL- HPFposition of the slide switch for each pair of channels."LPF" selects the low pass filter. "HPF" selects thehigh pass filter. Selecting "FULL" defeats the crossover functionsFREQUENCY ADJUSTMENTLPF40-240After selecting the crossover function, adjust the low pass or highpass frequency control with a small screwdriver through theopening marked “LP/FREQ.” or "HP/FREQ.". Turn CW toset to a higher frequency, CCW to set to a lower frequency.BASS-BOOSTONPOWEROFFTurning the “BASS BOOST” switch to “ON” increasesthe level of frequencies around 45Hz by 12dB.2.3 Operation- Protection Circuits andL.E.D. Indicators“POWER.” L.E.D. INDICATOR- Provides a visual indicationthat the amplifier is turned on.PROTECT“PROTECT” L.E.D. INDICATOR- Provides a visualindication that a problem exists and the protection circuitry hasprotected the amplifier by shutting it down. Turn the systemoff and correct the problem before turning the system on.THERMAL PROTECTION- The amplifier will shut down if itstemperature exceeds a safe operating level. The amplifier will remain offuntil it cools to a safe operating temperature. Exercise care, the exterior ofthe amplifier may get uncomfortably hot to the touch before shutting down.OVERLOAD AND SHORT CIRCUIT PROTECTION- The amplifierwill shut down if a short circuit condition exists, or if electrical currentdemands exceed safe levels.7
