Spectrum PA is a portable PA system with built-in dual LED lighting arrays that fulfills your requirements of delivering great performance sound, exciting lighting effects and wireless Bluetooth convenience for both musical acts and Karaoke performances. Spectrum PA is a 2-way 200-watt bi-amplified system housed in a very trim enclosure measuring just 8.4 x 29.2 x 10.1” (212 x 740 x 257mm) HWD. The drive units are three 6 1/2 ” (165mm) woofers and a 1” (25mm) high-frequency compression driver, which span the full musical frequency range from 65-20kHz. Its internal amplifier is divided 130 watts to the woofers and 70 watts to the tweeter. The system has thermal and dynamic overload protection, so the sound is always clean and clear no matter how hard it’s pushed. However, it’s the built-in 5-mode LED lighting array that really sets Spectrum PA apart from everything else. There are countless small- to medium-sized events where top-quality Karaoke/PA sound and lighting effects are needed: weddings, karaoke contests, coffee house performances, recitals and more. In every one of these situations, expensive, complicated stacks of equipment and lighting are both inappropriate and unnecessary. Alto Professional’s Spectrum PA fulfills all these requirements with one easily-transportable, easy-to-set up unit.FeaturesThree channel mixer: line/mic 1, line/mic 2, and AuxXLR, RCA, 1/4 ” and 1/8” connectors2-Band (LF/HF) built-in EQ for each channelFull Bluetooth® capability for streaming input signals wirelessly (plus wireless linking of another Spectrum PA for stereo applications)Built-in dual LED arrays provide brilliant light showFive customizable lighting modes: Mood, Meter, Mix, Pulse, PartyBrightness control lets you adjust or disable LEDsCustom Color Control—easily adjust the desired mix of Red, Green, and Blue lightingAdds powerful sound and visual flair to any Karaoke event or other performanceUltra-portable form factor for clean, uncluttered setupsPerfect for any occasion where additional lighting equipment would add clutterStand-mountable with 35mm threaded pole socketRugged: Scuff-resistant black vinyl wrap and protective steel cornersEasily transportable: Lightweight (just 23 lbs.) and built-in handleSpecs System Type: 2-way bi-amplified powered loudspeaker with sound-reactive LED lightsPower Amplifier: Bi-amplified; 200 W peak: 130 W LF + 70 W HFHigh Frequency: (1) 1” (25.4 mm) neodymium compression driverLow Frequency: (3) 6.5” (165 mm) with 1” (25.4 mm) voice coilFrequency Response: 65 Hz – 20 kHzCrossover Frequency: 1.8 KHz, electronicMaximum SPL: 94 dB SPLLight Type: 38 tri-color (red-green-blue) high-intensity LEDs; 12 W totalLight Modes: 5 modes: Mood, Meter, Mix, Pulse, PartyLight Controls: Mode selection knob; color selection knob with RGB preview LED; brightness knobConnections: (2) XLR-1/4” (6.35 mm) TRS combination inputs (Channels 1 & 2) (1) 1/8” (3.5 mm) TRS/stereo input (Channel 3) (1) RCA (line-level) stereo input pair (Channel 3) (1) XLR link output (1) IEC AC power connectionEqualization: 2-band (LF, HF) for Channels 1 & 2Bluetooth: A2DP streaming audio with full stereo link when using 2 Spectrum PA unitsProtections: Thermal, overloadEnclosure: Trapezoidal wood cabinet MDF enclosure with vinyl wrap; black metal protective corners; molded, ergonomically designed plastic handle; 4 rubber feet; 36 mm pole socket for stand mountingAC input: 100 V AC, 50/60 Hz (+10%) 110-120 V AC, 50/60 Hz (+10%) 220-240 V AC, 50/60 Hz (+10%)Fuse: 100-120 V T1.6AL AC250V 220-240 V T800mAL AC250VDimensions (H x W x D): 29.16” x 8.36” x 10.12” / 741 mm x 212 mm x 257 mmWeight: 22.4 lbs./ 10.2 kg.
