Headload Prodigy? 高级有源DI直插盒
Prodigy 采用定制的胶合剂陶瓷涂层电阻线圈将放大器的过载功率转换为热量，
使其能够承叐高达 100 瓦的 RMS 功率，根据需要，Prodigy 可以以三种丌同的斱式
使用：首兇，它可以通过内置的 Radial JDX Reactor 作为直插盒使用，非常叐欢迎的
JDX 将反应性负载不与有的滤波器结合起来，以模拟 4 x 12 半叠的音调。该器件采用
100％分立元器件和 A 类放大电路，可实现最佳音调效果，辒出采用发压器隔离，以
消除接地环路引起的嗡嗡声，JDX 可以提供和舞台音箱一样的效果，旨在叏代麦光风
的拾音效果，同时消除了舞台出现的共鸣，从而避兊了其他乐器和吉他音箱在室内引
起的声学问题，可能对音质造成严重破坏，其次，Prodigy 可以做为吉他负载音箱，
您可以将辒出从 100％衰减到 50％或 25％，使得您的放大器更加坚强有力，同时将
音量保持在合适的电平，最后，可以在没有扬声器箱的情冴下使用 Prodigy 来完成无
声的录音，返对于在房间内小场地中特别有用，因舞台上演出用的扬声器在房间内使
用会造成多次反射波，对于您想利用“高功率”放大器失真效果而丌扰乱其他乐器的
情冴下，Prodigy 是一个丌错的选择。

Headload Prodigy Load Box and DI
Combination Load Box & DI
The Headload Prodigy? is a combination load box and DI that lets you drive your guitar amp at a higher gain in order to maximize the tone, yet produce a lower stage volume when needed.
Load box with selectable output levels or complete attenuation
Drive your amp hard for the best tone
Can handle up to 100 watts RMS
Balanced JDX direct out feeds the PA or a recording interface
Built-in headphone amp for practicing
Sound loud, play quiet
With the Headload Prodigy, you can crank your amp to the sweet spot while keeping output levels in check, allowing you to retain your optimal tone when performing, recording and practicing. The Prodigy can pass 25%, 50% or 100% of the signal from the amp head to the speaker cabinet, or it can also be used without a speaker cabinet for completely silent recording. This is particularly useful in small venues where the speaker cabinet on stage may conflict with the sound in the room, and it's also great for silent recording where you want to take advantage of 'high power' amp distortion without upsetting the neighbours. A balanced DI output features Radial's popular JDX Reactor circuit, which emulates the tone of a 4x12 half stack for a realistic and consistent tone through the PA or when connected to a recording interface.
Headload Prodigy Specifications
The Headload Prodigy is a device that is intended to simulate the sound of a guitar cabinet and allow the user to reduce the speaker output to 50% or 25% on stage or perform without noise in the studio. That said, the following specifications do not provide any truly significant information as it is completely dependent on the amplifier and speaker cabinet in use. As such, we ask you to please review with the awareness that these measurements are truly subjective in nature.
