Features
• Rated power output of 100 W (at 4 Ω) and 165 W
(at 2 Ω).
• Class D Technology* 1
• For car audio units without a line output, direct
connection (High Level Input Connection) to the
speaker output of your car audio unit can be made
using a speaker-wire-to-RCA adaptor (not
supplied).
• High-level sensing turn-on feature allows this unit
to be activated without the need for a REMOTE
connection.
• Built-in HP (high-pass), LP (low-pass), and BP
(band-pass) filter for CH 1/2, CH 3/4, CH 5/6, and
CH 7/8.
• Protection circuit and indicator provided.
• Pulse power supply* 2 for stable and regulated
output power.
*1 Class D Technology
The Class D Technology is a method to convert and
amplify music signals with MOSFETs to high-speed pulse
signals. Furthermore, it features high efficiency and low
heat generation.
*2 Pulse power supply
This unit has a built-in power regulator which converts
the power supplied by the 12 V DC car battery into high-
speed pulses using a semiconductor switch. These
pulses are stepped up by the built-in pulse transformer
and separated into both positive and negative power
supplies before being converted into direct current
again. This is to regulate fluctuating voltage from the car
battery. This lightweight power supply system provides a
highly efficient power supply with a low impedance
output.
