A wide frequency response of 10 Hz to 40 kHz (± 0.5 dB), with ultra-low noise and distortion, delivers the full fidelity of the source material. Each channel has an independent level control and status LEDs for signal activity, clipping and protection; the rear panel has balanced 1\/4 inch TRS and Euroblock inputs and binding post outputs for bare wire, banana plugs or spade connectors. Whether it drives two pairs of monitors, two bridged pairs for high-power stereo or a multi-zone system, the SLA4 offers fidelity, flexibility and durability.\u003c\/p\u003e\n\u003ctable style=\"border-collapse:collapse;margin:6px 0 18px;width:100%;max-width:100%;table-layout:fixed;\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:12px 8px;text-align:left;border:1px solid #DDE2E8;vertical-align:top;word-break:normal;overflow-wrap:break-word;width:55%;color:#5a6170;font-size:13px;text-transform:uppercase;letter-spacing:.05em;\"\u003eRMS at 8 Ω (140 W at 4 Ω)\u003c\/td\u003e\n\u003ctd style=\"padding:12px 8px;text-align:left;border:1px solid #DDE2E8;vertical-align:top;word-break:normal;overflow-wrap:break-word;font-weight:bold;color:#006d77;font-size:17px;\"\u003e4 x 100 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:12px 8px;text-align:left;border:1px solid #DDE2E8;vertical-align:top;word-break:normal;overflow-wrap:break-word;width:55%;color:#5a6170;font-size:13px;text-transform:uppercase;letter-spacing:.05em;\"\u003eBridged at 8 Ω\u003c\/td\u003e\n\u003ctd style=\"padding:12px 8px;text-align:left;border:1px solid #DDE2E8;vertical-align:top;word-break:normal;overflow-wrap:break-word;font-weight:bold;color:#006d77;font-size:17px;\"\u003e2 x 280 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:12px 8px;text-align:left;border:1px solid #DDE2E8;vertical-align:top;word-break:normal;overflow-wrap:break-word;width:55%;color:#5a6170;font-size:13px;text-transform:uppercase;letter-spacing:.05em;\"\u003eFrequency response ± 0.5 dB\u003c\/td\u003e\n\u003ctd style=\"padding:12px 8px;text-align:left;border:1px solid #DDE2E8;vertical-align:top;word-break:normal;overflow-wrap:break-word;font-weight:bold;color:#006d77;font-size:17px;\"\u003e10 Hz - 40 kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:12px 8px;text-align:left;border:1px solid #DDE2E8;vertical-align:top;word-break:normal;overflow-wrap:break-word;width:55%;color:#5a6170;font-size:13px;text-transform:uppercase;letter-spacing:.05em;\"\u003eHum and noise below clipping\u003c\/td\u003e\n\u003ctd style=\"padding:12px 8px;text-align:left;border:1px solid #DDE2E8;vertical-align:top;word-break:normal;overflow-wrap:break-word;font-weight:bold;color:#006d77;font-size:17px;\"\u003e\u0026gt; 100 dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch3 style=\"font-size:17px;font-weight:700;color:#0D1B3E;text-transform:uppercase;letter-spacing:.06em;margin:30px 0 12px;padding:0 0 7px;border-bottom:2px solid #006D77;\"\u003eKey features\u003c\/h3\u003e\n\u003cul style=\"margin:0 0 14px;padding-left:20px;\"\u003e\n\u003cli style=\"margin:0 0 6px;\"\u003e\u003cstrong\u003e4-channel linear power amplifier\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli style=\"margin:0 0 6px;\"\u003e\n\u003cstrong\u003e100 W per channel\u003c\/strong\u003e at 8 Ω, 140 W per channel at 4 Ω\u003c\/li\u003e\n\u003cli style=\"margin:0 0 6px;\"\u003e\n\u003cstrong\u003e280 W bridged\u003c\/strong\u003e per channel pair at 8 Ω\u003c\/li\u003e\n\u003cli style=\"margin:0 0 6px;\"\u003e\u003cstrong\u003e1\/4 inch TRS and Euroblock inputs\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli style=\"margin:0 0 6px;\"\u003e\u003cstrong\u003eMulti-way binding post outputs\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli style=\"margin:0 0 6px;\"\u003e\n\u003cstrong\u003e10 Hz - 40 kHz frequency response\u003c\/strong\u003e (± 0.5 dB)\u003c\/li\u003e\n\u003cli style=\"margin:0 0 6px;\"\u003e\u003cstrong\u003eSmartFan adaptive cooling system\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli style=\"margin:0 0 6px;\"\u003e\u003cstrong\u003eToroidal transformer\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli style=\"margin:0 0 6px;\"\u003e\u003cstrong\u003e1U rackmount\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 style=\"font-size:17px;font-weight:700;color:#0D1B3E;text-transform:uppercase;letter-spacing:.06em;margin:30px 0 12px;padding:0 0 7px;border-bottom:2px solid #006D77;\"\u003eFront panel controls and indicators\u003c\/h3\u003e\n\u003cp style=\"margin:0 0 12px;\"\u003eThe power switch sits in the centre, with two channel level controls on each side. The level controls are detented and calibrated in dB: fully clockwise (0) is maximum level and full attenuation is at - infinity. Each channel has a Signal LED, which glows when the output is within approximately 30 dB of full scale, and a Clip LED, which lights when the output is near or at clipping. Channels 1 and 2 share a Protect LED, as do channels 3 and 4; it shows protect mode with the output muted and also lights during power up and down.\u003c\/p\u003e\n\u003ch3 style=\"font-size:17px;font-weight:700;color:#0D1B3E;text-transform:uppercase;letter-spacing:.06em;margin:30px 0 12px;padding:0 0 7px;border-bottom:2px solid #006D77;\"\u003eInputs and outputs\u003c\/h3\u003e\n\u003cp style=\"margin:0 0 12px;\"\u003eThe 1\/4 inch TRS inputs (tip positive, ring negative, sleeve ground) and the two removable Euroblock barrier strips take balanced or unbalanced signals from a mixer, preamplifier, crossover or EQ. ART recommends balanced connections for cable runs longer than 20 feet, and a 1\/4 inch input and the Euroblock connection of the same channel can be used together to link the signal to another amplifier channel. The multi-way binding posts accept bare wire, banana plugs or spade connectors.\u003c\/p\u003e\n\u003ch3 style=\"font-size:17px;font-weight:700;color:#0D1B3E;text-transform:uppercase;letter-spacing:.06em;margin:30px 0 12px;padding:0 0 7px;border-bottom:2px solid #006D77;\"\u003e2, 3 or 4 channel operation\u003c\/h3\u003e\n\u003cp style=\"margin:0 0 12px;\"\u003eTwo Stereo \/ Bridge switches bridge channels 1 and 2, channels 3 and 4, or both pairs, so the SLA4 can be configured for 2, 3 or 4 channel applications. In bridged mode the input goes to channel 1 (or 3), the loudspeaker connects across the two red binding posts of the pair and the channel 1 (or 3) level control sets the output. ART specifies loudspeakers of 4 Ω or more per channel in stereo and 8 Ω or more in bridge mode.\u003c\/p\u003e\n\u003ch3 style=\"font-size:17px;font-weight:700;color:#0D1B3E;text-transform:uppercase;letter-spacing:.06em;margin:30px 0 12px;padding:0 0 7px;border-bottom:2px solid #006D77;\"\u003eCooling and protection\u003c\/h3\u003e\n\u003cp style=\"margin:0 0 12px;\"\u003eThe external heatsinks carry most of the heat away. At low to moderate signal levels the rear variable-speed fan idles at low speed and switches to a higher speed when the internal temperature rises; if the heatsinks reach 194 °F the amplifier mutes until it cools down enough for safe operation. The output circuitry is fully protected from shorts, opens, over-current and over-voltage, with a relay that disconnects the outputs and returns to normal operation once the fault is removed.\u003c\/p\u003e\n\u003ch3 style=\"font-size:17px;font-weight:700;color:#0D1B3E;text-transform:uppercase;letter-spacing:.06em;margin:30px 0 12px;padding:0 0 7px;border-bottom:2px solid #006D77;\"\u003eIn the box\u003c\/h3\u003e\n\u003cul style=\"margin:0 0 14px;padding-left:20px;\"\u003e\n\u003cli style=\"margin:0 0 6px;\"\u003eSLA4 power amplifier\u003c\/li\u003e\n\u003cli style=\"margin:0 0 6px;\"\u003eDetachable power cord (supplied with the equipment, per the owner's manual)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 style=\"font-size:17px;font-weight:700;color:#0D1B3E;text-transform:uppercase;letter-spacing:.06em;margin:30px 0 12px;padding:0 0 7px;border-bottom:2px solid #006D77;\"\u003eART SLA4: frequently asked questions\u003c\/h3\u003e\n\u003ch4 style=\"font-size:15px;font-weight:700;color:#0D1B3E;margin:18px 0 6px;\"\u003eHow much power does the SLA4 deliver?\u003c\/h4\u003e\n\u003cp style=\"margin:0 0 12px;\"\u003e4 x 100 W RMS at 8 Ω and 4 x 140 W RMS at 4 Ω; bridged, 2 x 280 W RMS at 8 Ω or 2 x 200 W RMS at 16 Ω.\u003c\/p\u003e\n\u003ch4 style=\"font-size:15px;font-weight:700;color:#0D1B3E;margin:18px 0 6px;\"\u003eCan I bridge only one pair of channels?\u003c\/h4\u003e\n\u003cp style=\"margin:0 0 12px;\"\u003eYes.
