Boss Ce-2 Analysis [top] Link

The CE-2 uses a sophisticated filtering system to maintain signal integrity despite the inherent noise of early BBD technology:

Before the signal hits the MN3007 BBD, it must pass through a sharp Low Pass Filter (LPF). Without this, high frequencies would create "clock noise"—a high-pitched whine or digital-like aliasing. The CE-2’s filter is aggressive. It rolls off high frequencies significantly (around 4kHz to 5kHz). boss ce-2 analysis
