2 Connections and Care of the Product Connections 1. Connect this equipment only to the type of AC power source as marked on the unit. 2. Always route AC power cords so that they are not likely to be walked on, or tripped over, or where they may be pinched by items placed on or against them. Always pay particular attention to cords at plugs and/or convenience receptacles and at the point where they exit from the product. 3. Do not defeat the inherent design features of the polarized plug. Non polarized line cord adapters will defeat the safety provided by the polarized AC plug. If the plug should fail to fit please contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the grounding- type plug. If you use this product in a country which only has two slotted receptacles in the house, you must use a three-pin adapter plug to earth ground the E (earth pin) of the power cord connected to this product. 4. Do not overload wall outlets, extension or inte- gral convenience receptacles as this could result in a risk of fire or shock. Care of the Product 1. Clean the product by dusting with a dry cloth. 2. Do not permit objects of any kind to be pushed and/or fall into the product through the enclosure openings Custom Installation 1. Your Sherbourn amplifier can be placed on any table or shelf. It can also be custom installed in a rack, and/or in a piece of cabinetry or furniture of your choice. It is however, important that if the am- plifier is going to be housed in an enclosed envi- ronment, that you allow for adequate ventilation. Despite the adequately sized heatsinks built into the amplifier, it is still important that good ventila- tion be provided. Do not install the amplifier di- rectly above another heat generating component such as another amplifier without adequate venti- lation. 2. If your amplifier is going to be placed in an en- closed space such as an armoire, it is essential that adequate ventilation be provided. We strongly sug- gest that the shelf on which the product is being placed includes a cutout of at least twenty inches by twelve inches (50 cm by 30 cm) directly underthe ventilation slots on the bottom of the ampli- fier. A similarly sized cutout should be made in the upper or rear wall behind the shelf so that free air can flow from beneath the unit to the outside atmosphere. Also allow a minimum of three inches (7.5 cm) free space above the product and two inches (5 cm) on either side of the product. This combination of space will allow for a free flow of circulating air to help keep the amplifier from over- heating. If your cabinet includes a number of prod- ucts, it may be advisable to install a quiet fan to assist the cooling process. 3. The dealership from which you purchased the product is an expert on custom installation proce- dures and can provide invaluable advice to help you make an aesthetically pleasing and trouble free installation. Front Panel Indicators With your amplifier connected to its preamp and receiving an input signal at its first POWER ON the blue LED will turn on with a full brightness. Should you not hear music through the speakers it could be that there is no signal to the input of your amplifier and you should check the preamp/con- trol center for proper settings and connections. Your amplifier front panel includes multiple blue LEDs (one per channel). Adjacent to these LEDs is a switch to allow you to turn them off should you wish to do so. Rear Panel Connections It is strongly recommended that you make all of your connections and check them thor- oughly before powering up your amplifier from the front panel switch. This will ensure that you do not accidentally short the output of the amplifier or encounter any electric shock or sparks or cause any initial and sur- prisingly loud signals to be played through your loudspeakers. 1. The connection between your Preamp/Control Center will be made discretely via a cable from the output of your Preamp to the input of your amplifier. 2. The amplifier gives the option (depending on your preamp) of making the connection with ei- ther an XLR Balanced Input or an RCA Unbal- anced Input. 3. If your system has a noisy ground connection or if you need to run a distant input cable to the

Your amplifier includes a 12V DC trigger input connector to allow for remote integration with your preamp/control center. If your preamp includes provision to output 12V DC to remotely turn on other equipment, you can use a control cable to connect the preamp to the trigger input of your amplifier to allow it to automatically turn on when- ever you turn on your preamp. We recommend that a shielded coaxial cable be used for this pur- pose. A removeable plug at the 12V trigger input Rear panel view of model 5/5210A showing nonfunctional channels in shaded areas (comes with the amplifier) shall be unplugged and wired with the 12V in the correct polarity. The in- put impedance of the 12V input is 2.2k ohms; it will accept an input voltage from 9V to 12V. 5. It is strongly advised that you only use the power cords supplied with the amplifier. Never use any other power cords with a smaller gauge than the one provided. Do not use an extension cord to in- stall your amplifier since it could effectively re- duce the current capacity supplied to the amplifier.
