The classic 6176 tube mic preamp and FET compressor served as the secret sauce for some of music history's most well-known artists and recording engineers. From artists such as Norah Jones to John Mayer, and producers like Tony Visconti and Jack Puig, the 6176 has contributed to the recordings of numerous chart-topping hits and critically acclaimed albums, further solidifying its reputation in the industry.
Behringer wants to keep that classic alive with the Behringer 676, a classic mic/line tube preamp and compressor with custom-built Midas transformers, premium 12AX7/ECC83S and 12AT7/6072 tubes for a warm and rich sound. In just a single rack unit, the 676 provides a versatile range of tonal possibilities that can bring that same timeless quality to any recording.
Freedom to Fine-Tune
676 is made for simplicity and ease of use. The preamp section features controls for input gain, impedance, polarity, high or low frequency shelf, as well as high or low boost/cut. It can even be operated independently of the compressor with the flip of the Join/Split switch.
This circuit has been praised by so many producers and engineers for its ability to give you complete freedom to fine-tune and bring the best out of any vocal or instrument before it hits the compressor.
Effortless Dynamic Control
Featuring a powerful FET compressor with an ultra-fast attack time of 20 to 800 microseconds, 676 ensures precise control over transients. Its adjustable release time, from 50 to 1100 milliseconds, allows for tailored control over dynamics. A vintage-style meter displays both gain reduction and output levels, providing essential visual feedback. This blend of speed, versatility, and classic aesthetics makes 676 an invaluable asset for any audio setup. It can go from slow and smooth leveling for vocals up to a fast and aggressive snap for drums and bass.
Ready for Your Studio!
The 2U rackmount chassis of 676 is extremely sturdy and is designed to take up only a small portion of your valuable rack space. It happily sits in a rack case if you sometimes record on location or want to use it for live sound applications where portability and mobility are key. Either way, 676 is sure to be a perfect fit in your studio. You can even wire up the preamp and compressor completely independent of each other.

Protect your investment with the Long & McQuade Performance Warranty
A warranty can be a very important factor when making a buying decision. Because repairs can be very expensive in terms of parts and labour costs, manufacturers usually only provide one year limited warranties that generally only cover items that malfunction due to a manufacturer’s defect. With an important purchase such as a musical
instrument or piece of studio gear, however, many people want to have the peace of mind in knowing that their investment will be protected should the product no longer be performing at 100%.
Because of this, Long & McQuade provides our customers with a FREE one-year Performance Warranty on most of our products. The Long & McQuade Performance Warranty supplements the manufacturer’s warranty to ensure that our customers receive complete “no hassle” warranty coverage within their first year.
How does the Long & McQuade Performance Warranty differ from most manufacturers' warranties?
- Performance Guarantee: Normal wear and tear is covered, so your product will be performing as well as the day you purchased it for the entire duration of the coverage. Band and Orchestral Performance Warranty does not include replacing pads or cleaning for woodwind instruments, unless deemed necessary by our repair staff. Ultrasonic cleaning for brass instruments will be provided if deemed necessary by our repair staff, but is not routinely offered under the Performance Warranty.
- Product Replacement: If your product cannot be fixed or costs too much to fix, we will replace it with the equivalent model for no additional charge. If this is not possible, a full refund will be provided.
- No Lemon Policy: Your product will be replaced should the same problem occur multiple times.
- Convenient: Easy drop off and pick up of the product at any Long & McQuade location.
- Guitar Setup: Guitars purchased at Long & McQuade come with 1 free setup, to be redeemed within 1 year for new guitars and 90 days for used guitars.
- Loaners Available: A loaner product may be given while the product is being repaired.
- Power Surge Protection: Your product is covered even if damaged from a power surge.
- Accessory Coverage: Any peripheral devices or accessories that come with your product (i.e. foot pedal, case) are also covered.
- Commercial Use Coverage: Music and recording professionals who purchase gear for “heavy-use” commercial purposes will still be covered.
Long & McQuade reserves the right to restrict the purchase of additional years of Performance Warranty. Used products come with a 3-month Long & McQuade Performance Warranty. Some products (i.e. computers, software, cymbals and other items) are covered only by the manufacturer‘s warranty. Consumables (i.e. strings, reeds, drum sticks, batteries, tubes, cross faders) are excluded as they are designed to be replaced. Cosmetic Damage, Accidental Damage, or problems caused by Humidity or Temperature Issues are not covered. Speakers damaged by overpowering are generally not covered. Our coverage does not provide compensation for loss of use. As of June 2018 the Performance Warranty is no longer transferable. The warranty is only valid in Canada.
Purchasing additional years of coverage
Some manufacturers provide warranties for longer than 1 year; however, these are usually limited warranties that do not provide the same coverage as the Long & McQuade Performance Warranty. Customers interested in more complete and convenient (but not necessarily longer) coverage are still able to purchase additional years of the Performance Warranty.
If you are interested in receiving this coverage for longer than one year, you have the option of purchasing additional years of the Performance Warranty. The pricing is as follows:
- NEW products: Starting at 4% of the current new selling price to double the warranty from 1 year to 2 years. Starting at 4% for each additional year.
- USED products: Starting at 4% of the current new selling price to increase the warranty from 3 months to 1 year. Starting at 4% for each additional year.
- GUITARS: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year. $45 maximum. An additional free setup is not included with additional purchased years of Performance Warranty.
- BAND and ORCHESTRAL instruments: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year.
