Zapco Studio-D amps put big power in a small chassis. But these little beasts aren’t just small, and they aren’t just powerful. They sound  great! They had to earn the Zapco name before we put them into production. These amps are loaded with all the advanced features you would expect…and more! They have crossovers, bass boost, both RCA and Speaker level inputs, and preamp outputs to send signal to another amp. The ST-D amps also have a dash remote control. Finally, the ST-D amps have Bluetooth Streaming, so your Smart Phone, iPad, or other Bluetooth device can be a portable music source for your sound system.

When the Studio D BT amps are installed they work just like any other amps with your head unit. But if you fire up the music on your phone, tablet, or other Bluetooth smart device, these amps will automatically switch over to Bluetooth to grab that signal.

 

Our three higher power studio D.BT amps all share the same Compact Studio chassis. It’s less than an inch longer than the Class A/B ST-4X at 165mm x 300mm. And this chassis can house a 5-Channel amp, a 4-Channel amp and a high power stereo unit. The upgraded TI technology means these amps are also 90% efficient, just like the Micro-amps. So again...the power to size is huge. First is the Studio ST-105D.BT. The ST-105D.BT is a 5 channel amplifier with 120 Watts RMS/channel @ 4Ω and 200 Wats RMS/channel @ 2Ω with less than 0.5% THD+noise for the mids and highs and an whopping 380 Wats RMS at 2Ω for the bass. That’s not 1Ω power... it‘s 2Ω power. Enough for some very serious bass. Next up is the Studio ST-204D.BT. This is a 4-channel amp with 180 Watts RMS/Channel x 4 @ 4Ω and 560 Watts RMS/Channel x 2 on a 4Ω bridge at less than 0.5% THD + noise. That’s 1120 Watts RMS of full range power from a compact 4 channel amplifer.  Finally we have the Zapco Studio ST-402D.BT 2 Channel, full range Class D amplifier.  This amp has 380 Watts RMS/Channel @ 4Ω and 550 Watts RMS/Channel at 2 Ω and 1100 Watts on a 4Ω Bridge.

These amplifiers are less than 1/2 the size of any similarly powered amplifiers we have ever made, and just like the Micro-amps, the compact Studio D.BT amps have all the expected features plus Bluetooth streaming.
