6. KRAMER SIMPLE CREATIVE TECHNOLOGY Installing the 910 in a Rack Installing the 910 in a Rack This section describes how to install the 910 in a rack Before Installing in a Rack Before installing in a rack be sure that the environment is within the recommended range 5 lo 45 C 41 to 113 Operating humidity range 10 to 90 RHL non condensing Storage temperature range 20 to 70 C 4 to 158 F Storage humidity range 5 to 95 RHL non condensing O CAUTION When installing on a 19 rack avoid hazards by taking care that 1 Itis located within the recommended environmental conditions as the operating ambient temperature of a closed or multi unit rack assembly may exceed the room ambient temperature 2 Once rack mounted enough air will still flow around the machine 3 The machine is placed straight in the correct horizontal position 4 You do not overload the circuit s When connecting the machine to the supply circuit overloading the circuits might have a detrimental effect on overcurrent protection and supply wiring Refer to the appropriate nameplate ratings for information For example for fuse replacement see the value printed on the product label 5 The machine is earthed grounded ina reliable way and is connected only to an electricity socket with grounding Pay particular attention to situations where electricity is supplied indirectly when the power cord is not plugged directly into
7. the socket in the wall for example when using an extension cable ora power strip and that you use only the power cord that is supplied with the machine How to Rack Mount To rack mount a machine 1 Attach both ear brackets to the machine To do so remove the screws from each side of the machine 3 on each side and replace those screws through the ear brackets 2 Place the ears of the machine against the rack rails and insert the proper screws not provided through each of the four holes in the rack ears Note e In some models the front panel may feature built in rack ears e Detachable rack ears can be removed for desktop use e Always mount the machine in the rack before you attach any cables or connect the machine to the power e If you are using a Kramer rack adapter kit for a machine that is not 19 see the Rack Adapters user manual for installation instructions available from http www kramerelectronics com Connecting the 910 Digital Audio Preamplifier 6 Connecting the 910 Digital Audio Preamplifier To connect the 910 as illustrated in the example in Figure 2 1 Connect the inputs e Connect an unbalanced stereo source for example a tape recorder to the left and right INPUT 1 RCA connectors e Connect an balanced stereo source for example a tape recorder to the left L L right R R and ground G terminals on the INPUT 2 terminal block connectors e Connect a digital aud
