DY2200+
DY2200+数字音频延时器提供标准的模拟平衡输入/输出接口，运用高速SHARC浮点 DSP作为运算核心，内部实现数字处理。内含时间轴实时拉伸和压缩算法，实现延时量的积累和释放，而在拉伸和压缩的过程中，声音保持不变调。The DY2200+digital audio delay provides standard analog balanced input/output interfaces, using high-speed SHARC floating-point DSP as the computing core and implementing digital processing internally. It contains real-time stretching and compression algorithms for the timeline, which enables the accumulation and release of delay, while keeping the sound tone unchanged during the stretching and compression process.
DY2300+
DY2300+is a simplified version of DY3000+, which compresses some functions and has a high cost-effectiveness. It also uses dual redundant power supply, providing a delay of 85 seconds, supporting remote control, and can achieve dual machine linkage through GPI/O interface.
DY3000U
DY3000U is a high-precision digital delay device designed specifically for synchronous broadcasting systems. Its goal is to counteract the impact of time differences caused by different transmission methods on synchronous broadcasting. It automatically enters a delay state when turned on and has digital/analog inputs and outputs, with an adjustable step size of one sampling period.
