User manual PARASOUND SCAMP

[. . . ] SCAMP is extremely flexible and can be configured in a variety of ways, so please take time to review this manual to make full use of its capabilities. Power SCAMP/Signal Controlled Amplifier AC Present 1 Outlet 2 Product Overview The Parasound SCAMP automatically triggers two internal 15 A relays whenever it senses an audio signal from a signal source such as a preamplifier or surround processor. 15 A relays control AC outlets on the SCAMP's rear panel. The audio signal level necessary to trigger the SCAMP is internally adjustable from 7 mV to 250 mV; the default level setting is 100 mV. (Refer to drawing #3) The SCAMP can also be triggered on from a DC source ranging from +5 Vdc to +12 Vdc. [. . . ] However, take care to mount the SCAMP away from sensitive low-level sources that might pick up hum radiated from the AC power cords connected to it. Making Connections to the SCAMP Audio Connections Connect the left and right line output of your preamplifier or surround processor to the left and right inputs of the SCAMP. (Due to the SCAMP's zero insertion loss, there is no signal degradation when inserting the SCAMP into the signal path between a preamplifier and power amplifier. ) Connect the left and right outputs of the SCAMP to your power amplifier or other component. An additional set of output jacks facilitates connecting additional amplifiers or other components. Both sets of output jacks are paralleled directly to the input jacks. Audio Signal Trigger Input Line Input Jacks Connect audio signal from preamplifier, etc. to trigger SCAMP on Alternate DC Trigger +5 to +12 Vdc Trigger Input Connect DC Source to trigger SCAMP on +5 to +12 Vdc Trigger Output.

Be sure that the wall outlet has enough current available to adequately power the equipment that the SCAMP will control. Connect the AC Cord from the electronic component that you want turned on first to OUTLET 1 of the SCAMP. Next, connect the AC Cord from the electronic component that you want turned on second to OUTLET 2 of the SCAMP. Note: You may connect AC power strips to either or both outlets of the SCAMP providing the current draw of the components connected to each power strip does not exceed 15 A. -2- DC Connections Triggering the SCAMP On from an External DC Source Connect a wire (22 AWG or thicker) from the ground and a +5 to +12 Vdc output connection of an external 100 mA DC source to the ground and +5 to +12 Vdc IN of the SCAMP. Triggering Components On with the DC Source from the SCAMP Connect a wire (22 AWG or thicker) from the ground and +12 Vdc OUT of the SCAMP to the ground and +12 Vdc input of the external component(s) that you want the SCAMP to trigger on up to 400 mA total. Connecting Multiple SCAMPs You can "daisy chain" up to four SCAMPs to build an 8 outlet sequential switcher with a 120 A capability. Internal jumpers inside the SCAMP allow you to adjust the turn-on delay time from 0 to 8 seconds. (Refer to drawing #3) Connect the ground and +12 Vdc OUT connector of the first SCAMP to the +5 to +12 Vdc IN connector of the second SCAMP and adjust its delay time to 2 seconds. Next, connect the ground and +12 Vdc OUT connector of the second SCAMP to the +5 to +12 Vdc IN connector of the third SCAMP and adjust its delay time to 4 seconds, and so on. Front Panel Indicators The SCAMP has three front panel mounted status LEDs. The amber AC present LED will illuminate whenever the SCAMP is plugged into a "live" AC outlet. Two green LEDs labeled Outlet 1 and 2 will illuminate when their corresponding outlets have been activated.

Additionally, there is a 15 A internal fuse for each AC outlet. These fuses will blow if too much current is being demanded from the outlets. [. . . ] For Returns: Call, write, or fax Parasound's Technical Services Department. If it is decided that the unit should be returned for inspection at Parasound, it must be packed in its original carton as well as an additional outer carton. An RA number will be issued which must appear on the outer carton. A note stating the nature of the defect should accompany the unit. [. . . ]
