The POWER indicator lights up green when the power is ON. If the amplifier is connected to an amp control device such as the ACD1 or ACU16-C and the amplifier has been commanded to enter STANDBY mode, this indicator will light orange. 2 TEMP indicator Lights up red if the heat sink temperature exceeds 85°C (185°F). 3 PROTECTION indicator When the protection system is active, the indicator lights in red. No sound will be output from the speakers, since the speakers are automatically disconnected from the amplifier’s outputs. The protection system actives in the following situations: • When the amplifier is turned on The protection system actives for approximately 10 seconds when the amplifier is turned on. After 10 seconds, the protection system deactivates automatically and the amplifier is ready for normal operation. • If the amplifier overheats The protection system activates if the heat sink temperature exceeds 85°C (185°F). The amplifier is muted if the heat sink temperature exceeds 90°C (194 °F). The amplifier operates normally after the amplifier cools down. 4 REMOTE indicator This indicator will light green if the amplifier is being controlled by an amp control device such as the ACD1 or ACU16-C. 5 CLIP indicator Lights up red when the output signal distortion on the corresponding channel rises above 1% — indicating that “clipping” has occurred because the signal level is too high. 7 8 9 0 7 MUTE indicator This indicator will light red if the amplifier is muted by an amp control device such as the ACD1 or ACU16-C. This indicator will also light red while the PROTECTION indicator is ON. 8 Volume control knobs Each control knob adjusts the volume of the corresponding channel, in 31 steps from -∞ dB to 0 dB. Note: Screw holes for security cover These four screw holes are for attaching a security cover to protect the volume setting. Since a security cover and screws are not included in the amplifier, please prepare a security cover the same size as indicated below and four M3 screws. 30 mm 0 108 mm 9 Air intakes The amplifier uses forced-air cooling. The variable speed cooling fan draws air in from the front and exhausts it through the rear. The cooling fan speed varies depending on the heat sink temperature: It operates at low speed when it is below 40 °C (104 °F), increases in speed according to increases in temperature, and operates at high speed when temperature exceeds 60 °C (140 °F). Please be sure that you do not block the air intakes or exhaust vents. Also, clean the filter elements regularly. If the air intakes are clogged with dust or debris, the amplifier will overheat, which may result in the amplifier to shutting down. Front Rear 6 SIGNAL indicator Lights up green when the corresponding channel’s output level exceeds 1 Vrms (equivalent to 0.2 W into an 8 ohms load, 0.4 W into a 4 ohms load or 0.8 W into a 2 ohms load). Air intake Air exhaust 0 Screw holes for handles These four screw holes are for the included handles. Fix the handles to the amplifier, using the included flat-head screws. 6 T5n/T4n/T3n Owner’s Manual  Controls and Functions ■ Rear Panel 2 4 3 51 1 Input connectors 6 8 7 4 DATA PORT jacks • 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 Cold • 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). 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. • BRIDGE mode In BRIDGE mode, channels A and B operates simultaneously, functioning as a single mono amplifier. 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]. 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. 6 SPEAKERS jacks • 5-way binding post output jacks • Speakon type output jacks Speakon type cable plugs (Neutrik NL4) can be connected here. 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. 8 AC IN connector Amplifiers purchased in the United States of America and Canada. 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. The amplifier requires very high-power so that it can demand high current from the AC service.
