CONTROLS AND DISPLAYS FRONT PANEL POWER BUTTON • The Power Button performs no function when the amplifier is powered off with the rear panel Master Power Switch. • When the rear panel Master Power Switch is powered on, the Model 7.250 is in Standby mode. Pressing the Power Button when the rear panel master panel switch is powered on will activate the power amplifier. When the Model 7.250 is activated, the front panel display lights blue.
CONTROLS AND DISPLAYS REAR PANEL 1 & 2. UNBALANCED/BALANCED INPUT 1 TO 7 CONNECTORS Provides audio input for the speakers connected through the unbalanced (RCA) inputs or balanced (XLR) inputs. The illustration below shows the appropriate cable pin-out of XLR connectors. Never make or break connections to the Model 7.250 unless the Model 7.250 and all associated components are powered off. Do not connect the outputs of one channel to the outputs of the other channel or to other amplifiers.
CONTROLS AND DISPLAYS 3. SPEAKER OUTPUT CONNECTORS Provide audio output for the speakers. Output connectors can accept bare speaker wires or most spade connectors. When using bare speaker wires, loosen the connector, insert the wire into the top of the receptacle, and tighten the connector. The same procedure should be used for spade connectors. 4. REMOTE TRIGGER INPUT Enables the Model 7.250 to be controlled by an external device with a 3.3V DC minimum to 24V DC maximum trigger output.
CONTROLS AND DISPLAYS will remain activated when power is restored. It is recommended that the Model 7.250 be set to Standby Mode before being powered off to prevent potential damage to the unit or your speakers. If the Model 7.250 is not trigger-connected to a controlling device, there is a potential for damage to the speakers if power is lost and restored with the Model 7.250 in active mode. 7. AC POWER CONNECTOR The AC input connector provides power to the unit with the supplied power cord.
OPERATIONS Your new Model 7.250 power amplifier is ready for operation after the speaker and the interconnect cables have been installed into their proper sockets. REMOTE TRIGGER POWER ON How to make connections for remote power-on using components equipped with a DC trigger jack: Using an accessory cable with a 1/8” mono mini-plug and the correct connector specified for your source device, follow the procedure below to connect the trigger-output jack on the rear of the source device to the Model 7.
OPERATIONS Do not plug the Model 7.250 directly into the “Switched Accessory” outlet of another device! These outlets are intended for use with low current draw products such as tuners, CD players or cassette decks. These outlets are not designed to handle the high current draw of a power amplifier. Using these outlets for a power amplifier is a significant safety hazard. SOURCE COMPONENT CONNECTIONS & OUTPUT SETTINGS Make all connections before powering on the Model 7.250.
