Chameleon Labs 7602 MKII Details
The Model 7602 MKII is the sequel to our smash hit 7602 Microphone Preamplifier/Equalizer. The 7602 MKII new features include: selectable mic impedance, LED input metering, upgraded knob styles, and two different power options--all of this for the same price as the original unit. The 7602 MKII ships with an inline power transformer (all regulation is done inside the unit). The rackmountable CPS-1 can also still be used, but is no longer required.
The Model 7602 MKII Microphone Preamplifier/Equalizer is based on a classic and revered design utilizing pure Class ‘A’ circuitry. This unit 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. The Model 7602 MKII represents a dramatic breakthrough in delivering vintage audio performance at an affordable price.
- Equalizer Section - (Selectable 3 band design with a flexible filter section)
- Filter - This is a high pass filter with 3db loss at 300Hz, 160Hz, 80Hz, and 50Hz with an 18db cut per octave slope.
- Low Equalization - This section has a shelving slope with four frequency selections: 220Hz, 110Hz, 60Hz, and 35Hz. This equalizer affects the selected frequency and all others below it. The gain control provides 20db of boost or cut.
- Mid Equalization - This section has a peaking characteristic with six frequency selections: 360Hz, 700Hz, 1.6k, 3.2k, 4.8k, and 7.2k. The gain control provides 20db of boost or cut.
- High Equalization - This section has a shelving characteristic with five frequency selections: 16k, 12k, 7k, 4.9k and 3.4k. This section adjusts the selected frequency and all others above it. The gain control provides 20db of boost or cut.

Chameleon Labs 7602 MKII Electronics
By employing classic circuit design, polystyrene capacitors, a gold contact ELMA gain selector and custom wound transformers, Chameleon Labs ensures that the Model 7602 MKII will exhibit classic audio sound.
The Model 7602 MKII has a transformer balanced input with a range between 20dB and 80 dB of gain. The separate line input is transformer balanced and accepts input levels from -20 to +10dB.
Chameleon Labs 7602 MKII Power Options
The Model 7602 MKII features two different power options:
- 24VAC Adapter: Each Model 7602 MKII ships with a mid-line power supply, type-dependent on country of operation. This is not a traditional "wall-wart" but simply an outboard AC transformer. DC filtering and regulation is accomplished inside the 7602 MKII itself.
-
CPS-1 Dual Power Supply: For users who prefer a rack-mounted power option, the Model 7602 MKII may instead be powered by the CPS-1 Dual Power Supply. The CPS-1 is offered as an optional accessory and can provide power to two 7602 MKII units. Users will need to acquire the DC Cable needed to connect the CPS-1 and 7602 MKII.
Chameleon Labs 7602 MKII Modification Options
-
Carnhill Transformer Option: Microphone input and line level output transformers are replaced by Carnhill premium transformers. Carnhill transformers take you a step closer to original designs (Carnhill is formerly St. Ives, a long time supplier of transformers to the high end market) and brings a richer depth and detail that edges out the original stock transformer.
-
Premium Modification Option: Microphone input and line level output transformers are replaced by Carnhill premium transformers. All capacitors are replaced by premium tantalum versions, and the output transistor is upgraded as well. This is the highest level of mod we offer, exclusively at Front End Audio. In addition to a richer depth and increased detail, a top end sheen and presence is introduced. |
