Ashly TRA-4075 TRA Series 4 Ch x 75Watts and similar items

Ashly TRA-4075 TRA Series 4 Ch x 75Watts Multi Mode Amplifier Convection Cooled TRA Series Amplifiers utilize our advanced, efficient amplifiers perfect for Low Impedance, 25V, 70V or 100V installations with modest power requirements. They also feature a switch-mode power supply with Class-D circuitry, providing an extremely power-efficient solution. All TRA Series amplifiers are convection-cooled, so there?s little maintenance after the installation, and no annoying fan noise. 4-channel configurations with power ratings of 75W and 150W per channel at 4 Ohms, 70V and 100V. A 6-step LED meter for each channel lets you monitor all levels. TRA amplifiers can drive 4 or 8 Ohm loads and 25V or 70V and 100V Constant Voltage lines simultaneously. Output transformers are internally mounted. All TRA audio controls are on the rear panel. The 150W models are capable of driving 25V Constant Voltage lines using the direct coupled 4 Ohm output. Features: Convection cooling 2 RU configuration Extremely low ambient noise Internally-mounted constant voltage transformers Extensive protection circuitry including output overcurrent protection, DC output protection, main supply rail overvoltage protection, in-rush limiting and mains fuse 6-Step signal level and clip LEDs Rear panel level attenuators for each channel Rear panel Gain Switch: +36 dB or +26dB input sensitivity Euroblock inputs/outputs Selectable input sensitivity (voltage gain) Remote stand-by control Adjustable turn-on delay up to eight seconds Safety/Compliance: TUV, CE, FCC, RoHS 5-Year Warranty Specifications: Model Ch. 4? 8? 70V 100V TRA-4075 4 75W 40W 75W 75W Frequency Response (8 Ohms): 20Hz?20kHz, 1.0 dB, -3dBu @ 80Hz Due to internal HPF Distortion (SMPTE, typical): 0.5%?8 Ohm load, 10dB below rated power Distortion (THD-N, typical): 0.5%?8 Ohm load, 10dB below rated power, 20Hz?20kHz Damping Factor (8 Ohm load, 1 kHz): 200 into 8 Ohms Input Impedance: 20k Ohms, balanced Input Sensitivity: 1dBu (75W), 4dBu (150W) Voltage Gain: 26dB, 36dB Selectable Maximum Input Level: +21dBu HPF: 80Hz 2nd Order, Non-defeatable Cooling: Convection Output Circuitry: Class D Amplifier/Load Protection: Output Overcurent, DC Output, Main Supply Rail Overvoltage, Chassis Temperature, Inrush Limiting, Mains Fuse Environmental 40-120 F, (4-49 C) noncondensing Front Panel Controls: AC Power Switch Indicators (LED color) Power: (Blue), Standby (Yellow), Protect (Red), Clip (Red) Signal Level -24dB, -18dB, -12dB, -6dB (Green), -3dB (Yellow), Clip (Red) Rear Panel Controls: Input Attenuators, Gain / Sensitivity: +26dB, +36dB, Remote Stand-by, Delay Connectors (each channel): Input: 3-Pin Euroblock Output: Euroblock Cordset: 3-Prong IEC TRA Models 4075 Channels : 4 Max Output Power: Per Channel, 80Hz?20kHz, 1% THD, All Channels Driven 4 Ohms: 75W 8 Ohms: 40W Constant Voltage Options: 80Hz?20kHz, 1% THD, All Channels Driven 25V (per channel): 75W 70V (per channel): 75W 100V (per channel): 75W Line Current Draw: All Channels Driven @ 4 Ohms Standby Mode: 39mA No Signal (Idle): 565mA Typical (1/8 power pink noise): 1.25A Max (1/3 power sine wave): 2.25A Thermal Dissipation: BTU/hr, All Channels Driven @ 4 Ohms Standby Mode: 15 No Signal : 113 Typical (1/8 power pink noise) : 145 Max (1/3 power sine wave): 150 Signal to Noise 20Hz?20kHz, Unweighted: 100dB Weights, Dimensions Power: Dimensions: 19?
