The Chameleon Labs 7622 microphone dual preamplifier has a transformer-balanced input with a range between 20 dB and 80 dB of gain. The separate line input is transformer balanced and accepts input levels from -20 to +10 dB.
The 7622 pre has been carefully constructed and individually tested for quality. It utilizes pure class 'A' circuitry, and is made with 100% discrete components, hand wound transformers and was fabricated to precisely match vintage counterparts manufactured in the early to mid 70's.
It is based on high audio performance design techniques. By employing classic circuit design, polystyrene capacitors, a gold contact gain selector and custom wound transformers; Chameleon Labs ensures that the Model 7622 will exhibit classic audio sound. It represents a dramatic breakthrough in delivering vintage audio performance at an affordable price.
Front Panel Controls: (Left to Right, per channel)
¢DI Button: This button routes the Direct Input jack into the unit.
¢48V Button: This button supplies 48 V.D.C. (Phantom Power) to the Microphone Input XLR jack.
¢˜ Button: This button reverses the phase of the unit 180.
¢Microphone / Line sensitivity: This pot controls input level for the microphone and line inputs. The microphone and line inputs have their own input connectors on the rear panel and a separate input transformer. Each rear input has its own section of the control on the input gain selector switch. The microphone section provides 20 to 80db of boost in 5db steps, and the line section provides +10 to -20db of adjustment.
¢Output: Acting as a console fader, this control is placed after the gain stage and before the output stage. This allows for trimming of the input signal between the 5 db steps of the input switch, as well as allowing the input to be 4 intentionally overdriven. The normal position for this control is wide open.
Connecting the Preamplifier
¢Audio Connection: Microphone input connections are made with the female XLR connector on the rear of the unit. This connector is wired with pin 2 HOT, pin 3 common and pin 1 is ground. The 48 Volt D.C. power is supplied on pins 2 and 3.
The Instrument (DI) connection is made using the balanced 1„4" TRS jack on the front panel. The connector is wired with the TIP being positive, The RING being negative and the SLEEVE being ground.
Line input connections are made with the male XLR connector on the rear of the unit. This connector is wired with pin 2 HOT, pin 3 common and pin 1 is ground.
Output connection is made using the male XLR connector on the rear of the unit. This connector is wired with pin 2 HOT, pin 3 common and pin 1 is ground.
What Makes Chameleon Labs Different?
Chameleon Labs is a new type of company, focused on delivering performance and value at a price previously thought impossible. How do they do it? By reinventing how global manufacturing is approached. Chameleon Labs engineers are not inexperienced kids in a garage, buying products that are designed and built in China. Chameleon Labs is comprised of audio professionals with many decades of experience in high-end pro audio gear. From its inception seven years ago, they pioneered the idea of "blended technology", using top-notch parts from the US, UK, and Europe combined with low-cost metalwork and assembly from China. This combination enables a superior performance level at a low price point.
Every Chameleon Labs product is first created and engineered here in the U.S. The goal is to achieve a specific sound through tedious testing in major U.S. recording studios and listening to numerous tracks and/or mixes with a very specific sonic target in mind. A new design must impress the best and brightest of our evaluation group before it ever reaches the factory floor.
Our product catalog varies by country due to manufacturer restrictions. If you change the Ship-To country, some or all of the items in your cart may not ship to the new destination.
