Description
AP4KAmplifiers 2x 1800w per channel Amplifier An impedance mode switch on the back panel of the amplifier allows the user to select full output power into either a two or four ohm load for maximum application flexibility. This means this compact two rack space amplifier can deliver up to 3600 watts of clean, pure power into either 4 or 8 ohm loads (bridged), making it a perfect solution for virtually any touring live sound, club system or installation.
Amplifiers 2x 1800w per channel Amplifier
An impedance mode switch on the back panel of the amplifier allows the user to select full output power into either a two or four ohm load for maximum application flexibility. This means this compact two rack space amplifier can deliver up to 3600 watts of clean, pure power into either 4 or 8 ohm loads (bridged), making it a perfect solution for virtually any touring live sound, club system or installation.
The internal signal path has been optimized and a toroidal transformer is used in the AP4K design - both serving to reduce hum and noise in practical real-world applications. It's three-tier Class-H design approaches efficiency normally associated with Class-D technology; yet provides the superior transient response and low distortion of the best analog designs.
Features
- Delivers 1800 watts per channel into either 2 or 4 ohm load
(3600 watts bridged into 4 or 8 ohms) - Proven Ultra Reliable Class-H Design
- Easily Handles Reactive Phase Shifted Loads
- Advanced Protection Schemes Including DC Current, Load, Thermal & Breaker Protection
- Transparent User-Defeatable Peak Limiter Circuits
- Soft Turn-On Circuit Protects Speakers and Prevents Nuisance Breaker Tripping During Power Up
- Concise Front Panel Metering and Status LED's
- Speakon™ and Binding Post Outputs
- Balanced XLR and ¼-inch TRS Inputs
- All-Steel Chassis Construction
- Made in Canada

Tips broke in the binding post
Size: 12 Pairs / 24 pcs, Size: 12 Pairs / 24 pcs
UPDATE:
Two tips broke off when unplugging them from the binding post and are now lodged in. Inexcusable and an utterly poor product.
Solid connection in the binding post with no wobble or wiggle. They require some force to insert into the binding post, but once they're in they remain snug. I also tried removing and reinserting a few times and the connection remained solid. I've used other plugs in the past that have a softer tip and easily deform after one or two insertions. These do not have that issue.

Does the job, easy use, a bit bulky not exactly as described
Size: 12 Pairs / 24 pcs
Bare wire can be intolerable to work with. Banana plugs make a positive secure connection. These plugs are a touch bulky. Nice to not have to deal with small screws. Use as large of gauge wire as possible. The description says no unintentional disconnections. I beg to differ the bite of teeth aren’t as good as described. Used a 16 gauge pure copper speaker wire and a teenager taught me how secure the wire really is by tugging on the wire not the banana plug pulling the wire free. It does the job, it’s not the latest and greatest. If you need easy get these. If you want slim secure banana plugs buy the small screw type.

GET THEM!!
Size: 12 Pairs / 24 pcs, Size: 12 Pairs / 24 pcs
Fully gold plated inside and out! I initially got the amazon basic connectors for the same price, but was disappointed in the tiny burgundy positive label they had. It was also very dirty inside the connector and it wasn’t gold plated through out the connector. These are excellent in quality and have a bright red ban on the connector! You wont be disappointed and beats out Sewell connectors for the price!

Decent, but be careful of frequent use.
Size: 12 Pairs / 24 pcs, Size: 12 Pairs / 24 pcs
The looks are very nice, functional if left alone once assembled. After that I would leave them alone otherwise you risk the main male portion just coming loose of the housing, sound quality is decent, nothing to write home about, but again, not very durable. If they could fix that 1 thing, these would be very good buy and value, the rest of each plug is hefty and well made.
