API 2500+ Stereo Bus Compressor<\/h2>\n

The API 2500+<\/strong> is a high-end stereo\/dual mono compressor<\/strong> that delivers legendary punch, tone shaping, and dynamic control, making it an essential tool for both mixing and mastering engineers. Housed in a 19-inch rack-mountable unit, the 2500+ offers dual-channel operation<\/strong> that can be configured for linked stereo processing or independent dual mono use, all while maintaining API's signature analogue sound quality.<\/p>\n

A key feature of the 2500+ is the patented THRUST\u00ae circuit<\/strong> - a unique high-pass filter placed before the RMS detector that preserves low-end punch while compressing, giving your mixes the \u201cchest-hitting\u201d energy that API is known for. Combined with adjustable threshold (-20 to +10 dBu), variable ratio, attack, and release<\/strong> times, and switchable \u201cOld\u201d (feedback) and \u201cNew\u201d (feed-forward) compression styles, the 2500+ gives engineers precise control over tone and transient response.<\/p>\n

Also included is the new Mix\/Blend circuit<\/strong>, allowing parallel compression or crossfading between dry and processed signal. With three operation modes - OFF, Cross (X), and Parallel (||) - this feature adds serious versatility for modern mixing workflows. The auto-makeup gain function<\/strong> ensures consistent output levels as you tweak compression settings.<\/p>\n

API's legendary 2520 on amps<\/strong> are at the core of the 2500+, ensuring rich harmonic content and unmistakable character. The unit also includes balanced sidechain inputs<\/strong>, soft\/medium\/hard knee options<\/strong>, and a fully discrete analogue signal path with a hard relay bypass for true signal transparency when bypassed.<\/p>\n
