Telecommunication Engineering Centre, New Delhi, under Department of Telecommunications (DoT), which, inter alia, is the Telegraph Authority for the purpose of Testing and Certification. The detailed procedure for Mandatory Testing and Certification of Telecommunication Equipment (MTCTE) under these rules are notified separately. The testing is to be carried out by Indian Accredited labs and based upon their test reports, certificate shall be issued by TEC. Pioneer’s new extra-efficient Class-D digital amplifiers mark a dramatic improvement in power output capability, yet are 50% smaller than the current GM-Series Class-AB amplifiers. That makes them more versatile in terms of installation as well as performance. Hopefully it doesn't burn my car down by the time I have a chance to take it out. Since that seems to be what happened to one guy. The GM-D9701 also features Pioneer's patented Protection Control System, which automatically adjusts the amplifier's settings to protect against short circuits, overloading, and thermal damage. This ensures that your amplifier and speakers remain safe and reliable over time. The Pioneer GM-D9701 is a powerful Class-D mono amplifier designed to deliver high-quality sound to your car's audio system. With a maximum power output of 2,400 watts, this amplifier is capable of driving even the most demanding subwoofers with ease.

EMC testing – Electromagnetic compatibility is the ability of the device to be able to withstand EMI radiation from other devices and work properly. Second original amplifier, I noticed a couple days ago no longer has the blue power light on. A month or so ago I noticed less sound like the old one. Thought nothing of it, well now the amp is dead. EMI testing- Electromagnetic Induction is the electromagnetic energy released by a device during its working which may interfere with the working of other electronic devices in its vicinity. For extra flexibility, a variable LPF makes audio frequency more adjustable according to subwoofer characteristics and personal listening preferences. The GM-D9701 LPF is adjustable from 40 Hz to 240 Hz. Edit. Replacement amplifier still going strong. 2 out of 2 original amplifiers failed. That makes 2 failed amps out of 3. Terrible. DO NOT BUY.Every new Pioneer Class-D amplifier has a wired bass boost remote control for optimal bass level adjustment according to listening preferences and music characteristics. Never mind my bad. Fuses went bad (have had two out of four shorted subsoofers all along killing amps.) Pioneer’s new extra-efficient Class-D digital amplifiers mark a dramatic improvement in power output capability, yet are 50% smaller than the current GM-Series Class-AB amplifiers.

Since it is now out of warranty, I'm planning on repairing it myself. I will post pictures of repairs made, with replacement parts linked. enjoy first class sound and powerful volume on a versatile system at half the size of other units Main Features An amplifier shouldn’t take up too much space, especially in your car. This Class-D amps might just be what you’re looking for. It combines a 1-Ohm stable circuit, installation flexibility and a superior high-power output. Speaker line input sensorWhat, you DON'T own a Pioneer head unit? Well, we won't hold it against you. In fact we'll even help you build onto your system. The GM-D9701's speaker level inputs allow you to connect your OEM unit (or any unit that doesn't have the typical RCA-type inputs) without having to buy add-on adapters. So, the install goes faster, you save money, and you've got a Pioneer amp in your vehicle.

One of the standout features of the GM-D9701 is its variable low-pass filter, which allows you to adjust the frequency range of the bass output to suit your preferences.
