Golden Age Project COMP-3A 1 Channel Vintage Style CompressorThe COMP 3A is a one channel vintage style Compressor Leveler. The signal path uses only discrete components like resistors, capacitors and transistors. The input and output is transformer balanced, using two different transformers, each one optimized for its purpose. This is the way audio components were built before integrated circuits became available. The circuit used in the COMP 3A is based on a classic design that uses an electro luminescent
The COMP-3A is a one channel vintage style Compressor / Leveler. The signal path uses only discrete components like resistors, capacitors and transistors. The input and output is transformer balanced, using two different transformers, each one optimized for its purpose. This is the way audio components were built before integrated circuits became available.The circuit used in the COMP-3A is based on a classic design that uses an electro-luminescent panel and a photoelectric cell to control gain. This gives the COMP-3A a unique, program dependent compression characteristics. In addition, the vintage style signal path adds a wonderful and musical character to the sound. The ease of use with only two main controls makes it very simple to achieve the desired sound. These attributes haVE made the original units a favourite of engineers and musicians worldwide.
This classic sound is now available at a very affordable price point with the COMP-3A.
Features:
• Vintage style electronics. No integrated circuits in the signal path.
• Transformer balanced input and output. Can drive almost any load - balanced or unbalanced.
• Selectable output transformer loading resistors by an internal jumper, will affect the high end frequency response.
• Uses a classic T4-style electro-optical attenuator to control gain with program dependent attack and release times.
• Very simple to operate with only two main controls, Gain and Peak Reduction.
• HF control can make the side-chain circuit more sensitive to mid and high frequency content.
• A big meter selectable to show gain reduction or output level at two different reference levels.
• Hardwire bypass switch for easy comparisons.
• XLR and TRS input and output jacks for flexible connections.
Link jack and switch for connecting to another unit for stereo operation.
• All external controls located on the front panel.
• External power supply to avoid interaction with the audio circuits and transformers.
• Compact 2RU half rack format. Two units can be mounted with our 19-inch rack kit, the UNITE BIG.
• A solid build quality that will last many years of normal use.

Small in size
Color: Grey
Very small, picture makes it look much larger than it is. Seemed more appropriate for a cat, and 6 month puppy figured it out in under 1 min. Not very challenging.

Excellent for boredom and learning
Color: Blue
Wonderful! Daughters very intelligent Australian shepherd loves this. She takes it out when he's bored, or has t been able to give as much one on one. Well made

My dog loves the toy.
Color: Grey
My little dog loves the puzzle toys. She doesn't really like the treats I got. I'll get better ones.

Keep my dogs occupied
Color: Grey
Great for the dogs. Challenging and makes them work at it but not so hard they can’t eventually figure it out.

Too easy for my Lab
Color: Blue
My lab figured this out in 30 seconds. I was hoping it would be a bit more challenging for him. Thankfully, it is challenging enough for my bunny!
