Audio controller TBL-75

The TBL-75 is a free-standing, 126-watt tabletop volume control with a headphone jack. It connects to the speaker outputs of an amplifier or receiver and can connect to a pair of speakers or just provide volume control for a pair of headphones. Connecting headphones disconnects the speakers in the room for private listening. An impedance switch on the TBL-75 allows installers to easily match the load of multiple speaker pairs to the amplifier impedance without the need for a speaker selector or other impedance-matching equipment. All Russound volume controls are made with precision autoformers for high-fidelity sound, excellent frequency response, no heat buildup, and maximum power transfer from the amplifier to the speakers. Freestanding design can be located on a desk, counter, or tabletop Controls a pair of speakers, headphones, or both Selects 11 steps of volume plus off Allows impedance matching for up to 16 speaker pairs per system Precision autoformers assure long life and superior performance Shipping Dimensions: 9.9" (W) x 2.5" (H) x 8.8" (D), (25.2 x 6.4 x 22.2 cm) Shipping Weight: 2.4 lbs (1.1 kg) Audio Output(s): Headphones: 1/4" (6.35 mm) TRS jack Connector(s): Spring terminals Frequency Response: 20 Hz - 20 kHz, +1.0/-0.5 dB at rated power Impedance Matching Type: Autoformer Max Wire Size: 14 AWG (1.9 mm) Power Handling: 126 watts peak, 42 watts RMS continuous per channel Speaker Impedance: Min: 4 ohms Volume Control: 12 steps including Off; total attenuation 43 dB
