This is a next-generation model that inherits the functions of the well-established XLS series. Improvements including the appearance have been made, and the processing power and operability of the DSP have been improved. All models have a lightweight design of 5kg or less to reduce the burden of transportation and installation.
■ DriveCore realizes weight reduction without compromising sound quality
Equipped with "DriveCore", a custom IC that integrates functions such as high-precision clock, modulation, error amplification, and feedback on a single chip, which is the heart of the amplifier circuit. Parts are reduced to the maximum without compromising power and sound quality.
The power supply adopts a lightweight and highly efficient switching power supply.
All models are light at 5kg or less and have excellent portability.
■ Output power beyond class
Class-D operation efficiently drives high-load subwoofers.
The Peakx limiter is installed to maximize the output performance while protecting the speakers.
■ Filter setting is possible by powerful DSP
PureBand crossover system with 24dB / oct Linkwitz-Riley filter. Any crossover point can be set every 1/12 oct within the range of 30Hz to 3kHz.
The type of filter can be selected from no filter, low pass, high pass and band pass.
■ Flexible input / output
Equipped with three types of input terminals: XLR, standard phone, and RCA. Input sensitivity can be selected from 1.4V and 0.775V.
The output terminal has a speaker and a binding post.
■ Equipped with necessary functions in good balance
Equipped with a liquid crystal display with backlight on the front panel. ON / OFF is possible by setting including LED of indicator. A lock function that prohibits operation of the front panel is also available.
A status signal is output from the rear panel to confirm normal operation from a remote location.
You can set the sleep mode to reduce power consumption with external contacts.
Equipped with an air cooling fan to efficiently cool the inside of the main unit.
■ Liquid crystal display with increased size
The size is larger than the conventional model. The menu structure has also been reviewed and operability has been greatly improved.
■ AUX terminal
The left pin can be used for sleep mode to reduce power consumption with external contacts.
The right pin outputs a status signal from a remote location to confirm normal operation.

タイトな低域と抜けの良い高域が魅力の2chパワーアンプ。出力は400W×2(8Ω)、重さはわずか5㎏で持ち運びやすく、小中規模のイベントにちょうど良いサイズです。出力端子はスピコンとバインディング・ポスト、入力端子はXLR/フォンだけでなくRCAも備えています。フロントの液晶ディスプレイを見ながらの簡単な操作で、ステレオ、ブリッジなどのアンプモードやクロスオーバーの設定が可能。高音質、軽量化を実現したオススメのパワーアンプです。

AMCRON XLSシリーズは、5kg未満と超軽量、そして高いコストパフォーマンスながらDSPを搭載した人気のデジタル・パワーアンプです。内蔵されているクロスオーバーは、フィルターなし、ローパス、ハイパス、バンドパスの4種類から選択することができるので、フルレンジ、サブウーハーなどスピーカーの特性に合った設定をすることができ、2ウェイ・システムを組む際にとても便利です。また業務用パワーアンプだと、入力はXLRとフォン、出力はスピコンだけという仕様が多いですが、XLSシリーズは、RCA入力、バインディングポスト出力も用意されているので、接続する際にコネクターを気にせず使うことができるというのも嬉しいポイントです。低域から高域まで全体的なバランスが良く、クリアでクセのないサウンドキャラクターは、トークイベント、運動会、学園祭、ライブといろいろな場所で活躍すること間違いなしの一台です。
