TCS Channelstrip

The API TheChannelStrip TCS

Features: API 512c Mic Preamplifier API 550A Equalizer API 527 Compressor API 325 Line Driver Complete patching facilities on rear panel Two ten segment LED VU displays Output clips at +30dBm The Channel Strip is a complete input module with mic pre, dynamics processing, precision EQ and output level control. With extensive signal metering, multiple balanced insert points and an output mute switch, The Channel Strip contains the best features of a large console input channel in a single rack space. It's the perfect choice for anyone looking for that high-performance API console sound. The result of thoughtful engineering, The Channel Strip includes everything needed to record an audio signal. It all starts with the famed 512c Mic Preamplifier, which includes the benefit of additional Mic, Line or Instrument input switching. Next is the 527 multi-mode Compressor with fully adjustable Threshold, Attack, Release, and Ratio controls on detented pots. The patented THRUST® circuit in the 527 gives your track the "in-your-face" punch that has made this circuit an award winner. Also included in The Channel Strip is probably the most recognized and revered API EQ of all time, the 550A three-band Equalizer with its switchable frequencies and 12dB of boost or cut. The 550A's High and Low frequency bands can be individually switched to be shelving EQs, and the "B.P. Filter" switch inserts a 50Hz to 15KHz bandpass filter. At the output of the unit is the 325 Line Driver, taken directly from API console designs with an output level pot and 10 segment meter. The meter can also be switched to show the output level of the preamp. Each of The Channel Strip's processing pieces can be switched in or bypassed individually, while a flip switch internally routes the compressor after the EQ if desired. Additional features include a sidechain input and the famous API 2520/transformer combination.



3124V Mic Pre

Features:

Like the API 3124+, the 3124V is a high quality, compact, 4-channel mic preamp. It is equipped with the RE-115 K mic input transformer and the proprietary output transformer found in all API mic pres and throughout the API product line. Additionally, the 3124V offers Variable Output Level Control and switchable 3:1 output transformer selection. The unit has an internal 48-volt phantom power supply, which is switchable for each channel, as well as -20dB pad switches that affect both the mic and Hi-Z instrument inputs, both located on the front panel.

The 3124V also features up to 65dB of gain. Additionally, the Hi-Z front panel inputs feed directly to the op amps, which allow a low level input such as a guitar or bass to be amplified without a matching transformer or direct box. These Hi-Z inputs can take levels as high as +20dBu, making them perfect for keyboards and other high level devices. The mic preamp outputs are on rear panel male XLR connectors.

512V Mic Pre

Features:  

Mic Preamp with 65 dB of gain Variable Output Level Control 3:1 Output Transformer Tap Selection Front and Back Panel Mic Input Access Line/Instrument Preamp with 45 dB of gain Front Panel Combo-style XLR + 1/4 inch Line/Instrument Input LED VU meter for Gain Level indication 20 dB pad switch, applies to mic/line/instrument 48v Phantom switchable power Traditional API fully discrete circuit design with 2520 Op Amp Features API's unique Five Year Warranty The API 512v is a mic / line / instrument preamp, world famous for its ability to provide a low noise (-129 EIN) and unusually good sounding front end for all types of audio applications. Sonically, it delivers the instantly recognizable API sound at an affordable price, and in the scalable API 500 Series format. Offering an impressive 65 dB of gain, the 512v includes front panel Variable Output control, switchable 3:1 output transformer selection, phantom power, switchable polarity, -20 dB pad, and Mic or Instrument/Line selector.

The front panel Combo-style XLR and 1/4 inch connector combined with rear panel mic access allows for additional flexibility when installed into an API lunchbox®, API's 10 position 500V vertical rack, or into an API console.

The API 512v remains faithful to the circuit designs of API's founder Saul Walker.

Artfully combining those circuits with API's proprietary transformers and the incomparable 2520 op-amp, the 512v is a highly musical and rich-sounding analog mic pre, equally at home in commercial recording spaces as it is in smaller home studios.

Fully featured and still hand assembled, the 512v exhibits the reliability, long life, and uniformity which are characteristic of all API products.



512c Mic Pre

Features:

Mic Preamp with 65 dB of gain Front and Back Panel Mic Input Access Line/Instrument Preamp with 45 dB of gain Front Panel Line/Instrument Input LED VU meter for monitoring output level 20 dB pad switch, applies to mic/line/instrument 48v Phantom switchable power Traditional API fully discrete circuit design Uses the famous API 2520 Op-Amp The API 512c is a mic / line / instrument preamp designed to provide a low noise, unusually good sounding front end for all types of audio systems. Sonically, it offers the distinct API sound at an extremely affordable price. Offering low noise (-129 EIN) and 65 dB of gain, the 512c includes phantom power, and switchable polarity, -20 dB pad and Mic or Instrument/Line selector. Front panel XLR and 1/4 inch connectors combined with rear panel mic access allows for additional flexibility when installed into an API lunchbox®, API's 10 position 500V vertical rack, or an API console. The API 512c remains faithful to the circuit designs of API's founder, Saul Walker. Fully featured and still hand assembled, the 512c carefully preserves the original sound character that made it so much a part of the early days of recording. Offering high headroom and a wide variety of inputs and input access points, it is equally at home in the commercial recording studio as it is in the home project studio. The 512c Mic/Line Preamp makes use of the 2520 op-amp and therefore exhibits the reliability, long life, and uniformity which are characteristic of all API products.
