User manual PEAVEY DPS 1000

[. . . ] Refer servicing to qualified service personnel. WARNING: To prevent electrical shock or fire hazard, do not expose this appliance to rain or moisture. Before using this appliance, read the operating guide for further warnings. Este s'mbolo tiene el prop--sito, de alertar al usuario de la presencia de Ò(voltaje) peligrosoÓ que no tiene aislamiento dentro de la caja del producto que puede tener una magnitud suficiente como para constituir riesgo de corrientazo. Este s'mbolo tiene el prop--sito de alertar al usario de la presencia de instruccones importantes sobre la operaci--n y mantenimiento en la literatura que viene con el producto. [. . . ] This function can be disabled by turning the threshold control completely counter-clockwise. 9. CHANNEL 3 THRU 5 ZONE ASSIGNMENT SWITCHES Switches used to route the background audio signal to the desired zone. Selecting a particular zone button routes the audio source associated with that particular channel to the desired zone. The zone assignment switches can be used to route the audio to one or more zones if desired. MASTER ZONE LEVEL CONTROLS Controls the signal level being sent to each zone amplifier. Normally these controls should be set at the 12:00 position and the overall system levels set using the various channel level controls. This setting yields the best compromise for system noise performance and signal headroom. ZONE ACTIVE LEDS Indicates whenever any signal activity is occurring in that particular zone. These LEDs will light whenever a signal level above 50 mW RMS occurs in the associated zone power amp. These indicators are helpful for setting up the zone signal levels. ZONE CLIP LEDS Indicates clipping may be occurring in that particular zone. These LEDs will light whenever a signal level of 35 W RMS occurs in the associated zone. Notice the ground terminal is shared by the low-Z input as well. Normally, conductor 1 should be the positive output feed from the associated equipment. For unbalanced applications such as microphones with single conductor shielded cables and other such single ended equipment feeds, jumper the Hi-Z negative input to ground, and wire the cable as follows: Cable shield Ñ ground Conductor Ñ Hi-Z positive. CHANNEL 3 THRU 5 RCA INPUTS Normal high-Z line inputs for use with cables fitted with RCA male connectors. These inputs are designed to accept normal line level unbalanced signals such as those from a tuner or any other suitable background music source. The dual RCA inputs are mixed together internally to create a mono signal from a stereo feed. If only a mono signal is supplied, then either RCA jack can be used. To create the correct gain structure for the RCA jacks, a new DPS 1000 unit has jumpers from the Hi-Z negative input to ground on channels 3-5. If your unit does not have such jumpers in place, and you intend to use the RCA jacks as inputs, it is suggested that you add the jumper to that particular channel. CHANNEL 3 THRU 5 HI-Z INPUTS Normal high-Z line input for cables without connectors. This high-Z input can be used for any line level signal feed, balanced or unbalanced. [. . . ] Connect only to a power supply of the type marked on the unit adjacent to the power supply cord. Never break off the ground pin on the power supply cord. For more information on grounding, write for our free booklet ÒShock Hazard and Grounding. " 7. Power supply cords should always be handled carefully. [. . . ]
