Legend Audio ATP 7500 manual Rear Panel Connections, Reset to Defaults, Control Signal Connections

0. Reset to Defaults

We recommend not using this feature unless there is trouble with any of the settings you have made. This is a quick way to return the unit to “out of box” conditions. This will also be used when there are updates to the firmware. Press “0” on the remote when in the main menu. You can toggle between “NO” and “YES” by using the SELECT button. Please exercise extreme caution.

CAUTION: USE EXTREME CAUTION WHEN USING THIS FEATURE AS IT COULD RETURN ALL YOUR SETTINGS TO FACTORY DEFAULTS.

Rear Panel Connections

Audio and Video Signal Connections

The rear panel is divided into different sections whereby the connectors are grouped together in a logical manner. Digital inputs are grouped together and are labeled “DIG1” through “DIG6”. Each of these six digital inputs are assignable to any of the nine labeled source inputs as previously discussed.

Most of the analog inputs with the exception of “CD”, “TAPE”, and “7.1 Audio” are grouped together where they are associated with a video input, each forming a vertical line of connectors.

For each of these labeled inputs, you can plug in one video input, allowing for a choice of the type of connection: either a choice of Composite Video and S-Video or Component Video and S-Video. The “7.1 Audio Input” is a special multi-channel analog pass-through that can be used for a DVD-Audio or SACD player.

The outputs are grouped into “MAIN OUT” and “RECORD OUT” sections. The “MAIN OUT” section has an eight channel (7.1) preamplifier output and 4 video outputs; two are Composite Video and one is S-Video and one is Component Video. ONLY the Composite and S-Video outputs carry the OSD signal. To correctly setup your ATP7500 using the previously discussed OSD menus, make sure to connect your screen to at least one of the Composite or S-Video outputs

and remember to select this input on your screen whenever you need to access the OSD of the ATP7500.

The “RECORD OUT” section has two audio/video outputs that you can use to connect to a VCR or a tape deck, for example. The audio outputs are fixed line level; they are not affected by the processor’s volume control setting. The video outputs are Composite Video and S-Video for each of the two “RECORD OUT” connections. These video outputs provide NO OSD information. There is also a digital output available on an optical TOSLINK connector located near the “DIGITAL INPUTS”. It may be used to connect to a CD-R recorder for example.

The “2nd Zone” section has one fixed output, one variable output and one second zone dedicated input that is accessible only from the “2nd Zone”. The “2nd Zone” has limited access to which input source may be selected; the dedicated “2nd Zone” input, CD, TAPE, or the AM/FM Tuner.

Control Signal Connections

The input labeled “IR INPUT” (infrared remote control) is designed to receive an electrical signal corresponding to the infrared signal of a remote device such as a repeater that may be installed in the “2nd Zone”.

The RS232 port allows the control of the ATP7500 from a distant programmed controller (such as a Crestron® system). Information about the RS232 codes can be obtained from ATI on request. The RS232 port can also be used to download software revisions for future upgrades.

There are three trigger outputs that can be used to control other components. Two are associated with the main zone and one with the “2nd Zone”. Each of them activates when their respective zone is turned on. The output labeled “12V Trigger” is rated at 200mA. The outputs labeled “2nd Zone Trigger” and “Main Zone” are dry contacts rated at 1A each. All triggers operate with a 5 second delay.
