    API TCS-II Channel Strip Mono Channel Strip with Mic Preamp, Compressor, EQ, and Line Driver with Rear-panel Patching and LED Peak Metering

    API TCS-II Channel Strip

    The API TCS-II Channel Strip is a testament to the legacy of API’s large-format consoles, offering a comprehensive front-end solution for your audio needs. The TCS-II brings an updated compressor, enhanced preamp controls, and peak metering, all encased in a rackmount unit. This Channel Strip is a rich blend of classic API modules, including the 512c Mic Preamplifier, 527A Compressor, 550A Equalizer, and 325 Line Driver. It’s equipped with extensive patching facilities, dual 10-segment LED peak metering displays, multiple balanced insert points, a sidechain input, and an output mute switch. Each processing section can be independently switched and bypassed, with an option to route the compressor pre- or post-EQ. True to API’s heritage, the TCS-II is outfitted with API transformers and 2510 and 2520 op-amps, ensuring authentic API sound quality.

    API 512c Mic Preamplifier

    • Rich in API’s signature sonic character, the 512c Preamplifier offers a line preamp at unity gain, an instrument preamp with 50dB of gain, and a mic preamp with 68dB of gain.
    • Features include a -6dB line pad, -20dB microphone pad, switchable +48V phantom power, a polarity inverter, and peak LED metering.
    • The 512c Preamplifier is powered by API’s 2510 and 2520 op-amps, ensuring genuine API sound.

    API 527A Compressor

    • The 527A Compressor section includes adjustable Threshold, Attack, Release, and Ratio controls, with options for feed-forward/feedback and hard-/soft-knee compression.
    • Features API’s unique Thrust for frequency-dependent sidechain control, a 10-segment gain-reduction meter, a sidechain input, and a Link switch for multiple-unit compression linking.
    • A Comp Bypass switch with hard-relay switching and an internal routing switch for post-EQ compression are also included.
    • The 527A Compressor uses 2510 and 2520 discrete op-amps.

    API 550A Equalizer

    • The 550A Equalizer is a revered classic, offering three bands of API equalization.
    • Each band has seven API-selected frequency centers, with up to 12dB of boost/cut per band.
    • Features reciprocal and repeatable filtering, shelf/peak switching for the Low and High EQ bands, and a bandpass filter.
    • Equipped with API’s Proportional Q for nuanced filter Q adjustments at extreme settings.
    • The 550A Equalizer utilizes a traditional, discrete API circuit design with 2520 op-amps.
