(5)-4 4 T5n/T4n/T3n Owner's Manual Introduction Thank you for your purchase of the YAMAHA T5n, T4n, T3n Series Power Amplifier. This series of power amplifiers was developed from Yamaha's wealth of experience in building PA equipment and its tradition of careful attention to every detail of circuit design. These power amplifiers feature high power -- thanks to EEEngine (Energy Efficient Engine) technology -- and superb quality together with superior reliability and stability, guaranteeing the highest possible audio performance. Features: · Three modes are provided to support a broad range of applications: STEREO mode which can be driven by two independent sources, PARALLEL mode in which a monaural source drives both channels, and BRIDGE mode in which the two internal amps function as a single high-power mono amp. Fix the handles to the amplifier, using the included flat-head screws. 6 T5n/T4n/T3n Owner's Manual 30 mm Controls and Functions Rear Panel 2 3 6 4 1 Input connectors 51 8 4 DATA PORT jacks 7 · XLR3-31 type input connectors The pins are wired as shown below (IEC 60268). An amp control device, such as the ACD1 or ACU16-C, can be connected to the DATA PORT jack for monitoring or controlling the amplifier from the external device. 5 AMP ID switch Hot Ground When an amp control device, such as the ACD1 or ACU16C, is connected to the DATA PORT jack 4, the AMP ID can be used to set the amplifier's ID. Cold 6 SPEAKERS jacks · 5-way binding post output jacks · Speakon type output jacks Speakon type cable plugs (Neutrik NL4) can be connected here. · Euroblock input connectors These are balanced input connectors. The included Euroblock connectors can be used to make connections here. Note: In PARALLEL and BRIDGE mode, only the channel A connector is active. Make sure not to input an audio signal to an inactive input terminal (channel B). 7 Ground screw If you are having a problem with hum or noise, use this terminal to connect to ground or connect to the chassis of the mixer, preamp, or other device in your system. 2 Mode switch · STEREO mode In STEREO mode, channels A and B are completely independent. · PARALLEL mode In PARALLEL mode, the channel A input signal is sent both to the channel A power amp and the channel B amp. The Channel B input connector does not function. 8 AC IN connector Amplifiers purchased in the United States of America and Canada. · BRIDGE mode In BRIDGE mode, channels A and B operates simultaneously, functioning as a single mono amplifier. This amplifier uses a NEMA L5-30 outlet. Connect the 30 A twist-lock connectors by orienting the locking L-shaped prong with the corresponding connector entry, then fully insert the three prongs. Twist the plug about 1/8 of a turn clockwise to lock the connector and plug. 3 GAIN switch This switch is used when changing the Gain of the A and B channels simultaneously. 32 dB: Setting of 32 dB 26 dB: Setting of 26 dB When monitoring or controlling from an amplifier control device such as the ACD1 or ACU16-C, set the GAIN switch to [26 dB] to avoid clipping if you plan to input signals with a maximum input level of +24 dBu. When the power amplifier is connected to the ACD1 or ACU16-C, the electronic volume control inside the amplifier will become effective, and the maximum input level will become +18 dBu if the GAIN switch has been set to [32 dB]. The amplifier requires very high-power so that it can demand high current from the AC service. Connections must be properly rated for reliable operation. If this device is to be rack mounted and transported frequently, be sure to support the rear end of the unit with mounting hardware that matches the size of the rack used. T5n/T4n/T3n Owner's Manual 7 Speaker Connections Speakers can be connected to the amplifier as shown below. Note that actual speaker impedance varies according to the connection method and the number of speakers. [. . . ] 1/3 power represents program material with extremely heavy clipping. Test signal: Pink Noise, bandwidth limited from 22Hz to 22kHz 1W = 0. 860kcal/h, 1BTU = 0. 252kcal Note that Line Voltage [V] x Line Current [A] = [VA], not equals to [W]. Inrush current: 6A (100V), 7A (120V), 14A (240V) T5n/T4n/T3n Owner's Manual 73 For details of products, please contact your nearest Yamaha representative or the authorized distributor listed below.
