User manual EVENT TR

[. . . ] The TR8 and 8XL feature the same woofer, tweeter, enclosure, and active 4th-order crossover as their critically-acclaimed forebear, the 20/20basTM. The TR6 and TR5 use the same woofers, tweeters, enclosures, and active crossovers as the award-winning Project StudioTM 6 and 5, respectively. All models are biamplified, coming equipped with newly-designed highefficiency amplifiers that provide high SPL (Sound Pressure Level) output, lower distortion, smoother amplitude and phase response, and extended bandwidth. The Tuned Reference amplifiers also boast significant improvements in signal-to-noise ratio, input common mode rejection ratio, and overall reliability. [. . . ] When oriented this way, the listener is in the "sweet spot, " which yields the 4 TUNED REFERENCE USER GUIDE most accurate stereo reproduction. If you need a wider sweet spot to allow for greater listener movement or for group monitoring, face the speakers in a slightly more open position, but never more than necessary. Finally, if you must mount the speakers substantially above or below ear level, you will also need to tilt the cabinets downward or upward to keep the driver components directly facing you. As you become more familiar with your speakers, you may find it helpful to move around in the soundfield to locate the optimum listening position for your particular monitoring environment. But if you follow the equaldistance, ear-level, face-on rules outlined above, you've already optimized their position for a single user in most situations. Connections and Operation Please refer to Figure 2 on page 5. Balanced XLR Line Input This jack accepts a male XLR connector, wired for either balanced or unbalanced operation. For balanced operation, please consult the pin wiring diagram on Page 5 or on the monitor's back panel. The Line 1 input is hardwired in parallel with the Line 2 input, so either may be used as an input or as a pass-through connection. Balanced 1/4" Line Input This jack accepts a male two-conductor 1/4" TS or three-conductor 1/4" TRS connector, wired for either balanced or unbalanced operation. For unbalanced operation with a TS connector, the minus signal is automatically grounded; with a TRS connector you have the option of leaving the minus input open or grounded. For balanced operation, which requires using a TRS connector, please consult the pin wiring diagram on Page 5 or on the monitor's back panel. TUNED REFERENCE USER GUIDE The Line 2 input connector is hardwired in parallel with the Line 1 input connector, so either may be used as an input or as a pass-through connection. Input specifications apply equally to both inputs. 5 INPUT SENSITIVITY -5dB INPUT CONNECTIONS BAL BAL UNBAL SIGNAL XLR 1/4" 1/4"­ RCA + PIN 2 TIP TIP ­ PIN 3 RING SHIELD PIN 1 SLEEVE SLEEVE -20dB MAX BALANCED INPUTS UNBAL INPUT POWER REQUIREMENTS 120V~ 60HZ 0. 8A 100W 220/240V~ 50/60HZ 0. 5A 100W 100V~ 50/60HZ 1. 0A 100W Figure 2. Tuned Reference rear panel connections and controls. Unbalanced RCA Line Input This jack accepts a male RCA connector, wired for unbalanced operation. However, due to it being an unbalanced input, we do not recommended using it in combination with either of the balanced inputs, as this will unbalance those inputs, possibly causing degradation of the audio signal. 6 TUNED REFERENCE USER GUIDE Input Sensitivity This control is used to compensate for different signal levels that appear at the input. The control has a 20dB range; when set at maximum (MAX), 0. 5V RMS input at the balanced ins or 0. 25V RMS at the unbalanced in will produce full amplifier output. Note that when the signal appearing at the input is too hot, the amplifiers may overload, causing distortion. If this occurs, attenuate (decrease) the Input Sensitivity by turning the control counter-clockwise. Power Switch Push to turn the amplifiers ON; push again to turn them OFF. [. . . ] We can accept for ser vicing only those units that are accompanied by an RA#. Units shipped without an RA# number will be refused. Tuned Reference Specifications Low Frequency Driver TR5: 5. 25"; TR6: 6. 5"; TR8/8XL: 8" magnetically shielded mineral-filled polypropylene cone with high temperature voice coil and damped rubber surround. High Frequency Driver TR5: 25mm magnetically shielded natural soft dome neodymium with ferrofluid-cooled voice coil.
