Before using this appliance, read the operating guide for further warnings. Este símbolo tiene el propósito de alertar al usuario de la presencia de "(voltaje) peligroso" que no tiene aislamiento dentro de la caja del producto que puede tener una magnitud suficiente como para constituir riesgo de corrientazo. Este símbolo tiene el propósito de alertar al usario de la presencia de instruccones importantes sobre la operación y mantenimiento en la literatura que viene con el producto. [. . . ] A switch closure from terminal 1 to mutes Channels 1 to 4. A switch closure from terminal 2 to mutes Channels 2 to 4. 24 V DC OUTPUT TERMINALS (24) Provides connection for a low current (20 mA) 24 V DC output for powering low current external add-on equipment. 5 CH 4 OUT RCA JACK (25) Provides a direct output of Channel 4 that is independent of EQ and muting. This output is ideal for music on hold applications. AUX OUT RCA JACK (26) Provides a line level output to drive external power amps, hearing assistance systems, or as a record output for taping. This output is after the EQ and Master Volume Control. LOOP IN/LOOP OUT JACKS (27) Functions as a preamp out/power amp in patch point. The Loop Out signal is a post EQ/Master Volume line level output. LINK SWITCH (28) Breaks the connection between the preamp and the power amp (Loop Out/Loop In). These two jacks are shorted together when the switch is in the "In" position. To use the Loop Out/In jacks as a patch point, the switch must be placed in the "Out" position. The line level output signal is present at the Loop Out jack regardless of switch setting. OUTPUTS (29) A direct output, as well as several isolated transformer outputs, are provided to allow the proper interface between the amplifier and the speaker system. The direct output allows direct connection to a 4 ohm speaker system. To use this output, disconnect the jumper between the 4 ohm terminal and the XFMR terminal. Connect the speaker (or speakers) from the GND terminal to the 4 ohm terminal. Channels 3 and 4 shall have screw terminals for the Low-Z inputs; screw terminals and RCA phono connectors for the High-Z inputs. Channels 1 through 4 shall have 24 volt phantom power for the Low-Z inputs. The Page input shall be transformer balanced (600 ohms) and shall have screw terminals for the input connection. The master section shall include one Master Volume level control, two EQ controls providing 10 dB boost or cut at 100 Hz and 10 kHz, and a "Contour" switch providing 6 dB of boost at 100 Hz and 10 kHz. The unit shall have two levels of automatic muting. Mute 1 shall give precedence to the Page input, and it shall override Channels 1 through 4, with a threshold control on the Page input. Mute 2 shall give precedence to Channel 1, and it shall override Channels 2 through 4, with a threshold control on Channel 1. The two mute lines shall have screw terminals for external mute control. The unit shall have a Channel 4 output that provides an RCA phono, non-mutable output of Channel 4. Provision for an external master volume control shall be made via screw terminals. The unit shall be packaged in a rugged metal chassis 17" wide by 3-1/2" high by 15-5/8" deep. [. . . ] It should not be placed flat against a wall or placed in a built-in enclosure that will impede the flow of cooling air. This product should not be placed near a source of heat such as a stove, radiator, or another heat producing amplifier. 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. [. . . ]
