Note:
●You have tow choices for your order:
①DIY KITS include all the L20.5 dual
channels components and PCB boards which need to solder by yourself;
①Finished board L20.5 dual channels AMP which have been rigorously tested by Audio Precision;
Features:
▲ Ultra low distortion circuit, HIEND design standard.
▲Adopt special CFP output and COSCODE input stage.
▲ Four pairs of original imported ONSEMI NJW 0302 0281 power tubes per channel.
▲All components are brand new genuine, non-bulk goods, to ensure quality.
▲Equipped with screws, insulation sheets, copper pillars, etc., only need to install the power tube and copper pillars by yourself.
Parameters:
◆Output power:
200W 8R, 400W 4R + -63V power supply.
125W 8R, 250W 4R + -50V power supply.
250W 4R, 500W 2R + -50V power supply
◆Maximum output current 15A, output maximum voltage sine wave + -63V. (+ -65V power supply)(NoteThe maximum voltage of L20.5 is+/-65V, and this mains voltage can fluctuate, sometimes high and sometimes low, so it is not recommended to exceed+/-55V
◆Quiescent current 20MA per channel
◆Static power consumption = power supply voltage * 0.02 (2W + -50V)
◆Power Supply Voltage: +-24V to + -65V
Recommended power supply voltage and radiator standard:
+ -35 to + -50V, radiator 0.5KG per channel
+ -40 to + -60V, radiator 1KG per channel
Gain GAIN = 31 times
Frequency response = 20-25K HZ -0.15DB. 10HZ = -0.7DB 20K HZ = -0.05DB
