Description:

Bring a more professional sound to your mix
Adding a dbx® 266xs Compressor/Gate to your live sound rig or studio gives you more dynamic control to help create a more polished, professional sound. Having compression in your audio chain gives you the ability to smooth out uneven levels, add sustain to guitars and fatten up your drums. It also makes it easy to bring vocals to the front of your mix - adding greater clarity and making them stand out from the surrounding instruments.

dbx knows compressors...after all we invented them! The 266xs is the latest in a long line of the world's most successful compressors from the inventors of the technology. Its patented Overeasy® compression technology provides smooth and musical performance while the AutoDynamic™ attack and release controls, found only on dbx compressors, puts great sound within easy reach. The 266xs can operate in stereo or dual-mono modes, has true RMS power summing and features quality XLR and 1/4" TRS inputs and outputs. It cuts no corners on visual feedback with gain reduction metering and easy-to-read backlit switches.

Features:

• Error proof operation to smooth uneven levels, add sustain to guitars, fatten drums or tighten up mixes
  
• New gate timing algorithms ensure the smoothest release characteristics
  
• Program-adaptive expander/gates
  
• Great sounding dynamics control for any type of program material

Description:

All Rockville pro audio cables are made with 100% copper which boosts the efficiency of the cable. There is nothing better than 100% copper. Most of the cheaper cables on the market do not use 100% copper, instead they make their cables with CCA (Copper Clad Aluminum). CCA cables do not perform on the level that 100% copper cables perform at. CCA will not conduct signals efficiently. A 12 gauge CCA cable will not even perform as well as a 14 gauge 100% pure copper cable, which will in turn, affect the performance and longevity of your equipment. If you find cables on the market that do not mention the copper content, there is a good chance that they are selling you a cheaper cable that is CCA and not 100% copper. Rockville pays an inspection company to oversee the manufacturing of the product to ensure that we provide a 100% Oxygen Free Copper Cable (OFC). Our OFC cables are less prone to oxidation, and will provide maximum signal transfer.

The other important factor of a cable is the shielding. Most of the good brands on the market have about 85% shielding coverage, so we decided to take our shielding a step further. Rockville cables are shielded with a tight copper mesh, covering 90% of the cable! The high percentage of coverage increases the ability to absorb the Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI) that suppresses signal and degrades the performance of equipment. Rockville Cable’s copper shielding provides great flexibility, maintains a durable structural integrity, while decreasing signal interference ensuring enhanced signal clarity with every use.

Features:

• Rockville RCXFM20E-B 20 Foot Nickel Plated Female to Male XLR Microphone Cable
• XLR Connectors with Internal Strain Relief for Rugged Reliability
• 100% Copper Conductors for Enhanced Signal Clarity
• 90% OFC Spiral Shield for Effective EMI and RFI Rejection and Flexibility
• Length: 20 Ft
