****** Page 2 ****** WARNING! Before you start your new HAMMER-EQ please read the following: ANY real tube product is sensitive to a high SPL environment. This may cause microphonics in a recording situation. Make sure you are able to shock mount and or place the unit in isolation if need be. Direct light will also affect tubes as well. PLEASE be sure to have at least one rack space between any tube products from the product above and below the unit. This will ensure your tube unit will not over heat. Over heating will cause damage to the tubes and shorten their life span. If possible, place the HAMMER unit in the top rack space to allow air flow. If you have received your unit via UPS/Fed-Ex/DHL, or any other courier, your HAMMER should have been double boxed for protection. If it was not double boxed, please contact your dealer and return the unit to them for a replacement. We demand ALL our units to be double boxed to help prevent damages during shipping.

****** Page 3 ****** Introduction Welcome to the Analog Sound of the HAMMER-EQ. This is an all tube product, so there are some basics you need to understand before using this product for the first time. Tubes are a component that have specialized and unique features. If you are a “pre” or baby boomer, born before 1957, you may recall using tubes in various products, such as radios, amplifiers, and televisions. So, this is just to refresh your memory. If you are a “post” baby boomer, this could be your first experience with tubes, so please pay close attention! (You will be tested at the end of this manual). Tubes are most efficient and effective when “warmed up.” This means, upon starting the HAMMER-EQ, you should allow the tubes to become fully heated before attempting to operate. The minimum amount of warm up time is approximately 15 to 20 minutes. Set up your instrumentation layout before powering up the HAMMER-EQ. Plug in your instrument or microphone while the unit is off. This will prevent unwanted noise such as “pops.” The same applies when you shut down. Allow a minimum of 25 seconds for the power to drain from the tubes properly. Then you can unplug your instrument or microphone. When placing the HAMMER-EQ in a rack, we recommend using the first tier or allow one x space in order to properly ventilate. Avoid overheating! Too much heat will reduce the life-span of your tubes. We also recommend strongly that you observe SPL and shock mount any tube product. A Designs Audio, Inc. has scoured the earth for the perfect combination of tubes for this unique quality sound. Go ahead, get started. Read the following pages carefully to become acquainted with the warmth and clarity that the HAMMER-EQ can deliver to your recordings. Please feel free to email A Designs via the website with any creative applications for the use of the HAMMER-EQ. We have included a few applications in this manual. We may just include your suggestion on our website! Congratulations on the purchase of your HAMMER-EQ! Most of all, have fun! Peter Montessi, President A Designs Audio, Inc.
