OPERATION

USING THE T 175 –Setup MENU

ANALOG AUDIO

The T 175 has nine analog audio inputs including 7.1 input. These analog inputs - Audio 1, Audio 2, Audio 3, Audio 4, Audio 5, Audio 6, Audio Front, Audio MP and 7.1 Input can be variably assigned to each Source.

Scroll to “Analog Audio” and then press [] to select and assign an analog audio input to the particular Source. There are three choices – Audio, 7.1 Input or Off.

When “Audio” is chosen, press [] and then [] keys to select and assign the desired audio input

– 1 to 6, Front and MP.

Select “7.1 Input” to choose the audio signal fed to “7.1 Channel Input”. If “Off” is selected, no incoming analog audio signal is selected by the particular Source.

NOTE

An incoming digital signal present at the assigned digital input will always take precedence over the assigned analog audio input, even if both are present. To maintain the analog audio input for the particular Source, select “Off” at the “Digital Audio” setting of the same “Source” menu.

GAIN

Gain adjustment allows all sources to play back at the same volume so you don’t need to adjust the volume every time a new source is selected. It is generally preferable to reduce the level of the loudest source rather than making louder the softer sources.

Scroll to “Gain”, press [] and then [] to step through the desired level from -12dB to 12dB.

DIGITAL AUDIO

To take advantage of the T 175’s high performance surround and digital audio circuitry, it is advisable that its Digital Audio inputs are selected.

There are three types of Digital Audio input for the T 175. These are HDMI, Optical and Coaxial digital inputs. A fourth option is“Off” whereby no incoming digital audio signal is selected by the particular Source.

The desired digital audio input for a particular Source can be selected by scrolling to “Digital Audio”, press

[] and then [] to step through the desired digital input source. After finalizing which type of

Digital Audio input is desired, press [] and then [] again to select the specific Digital Audio input.

There are eleven Digital Audio inputs selectable for the T 175. They are the following

HDMIHDMI 1, HDMI 2, HDMI 3, HDMI 4

OpticalOptical 1, Optical 2, Optical 3, Optical Front

CoaxialCoaxial 1, Coaxial 2, Coaxial 3

NOTE

An incoming digital signal present at the assigned digital input will always take precedence over the assigned analog audio input, even if both are present. To maintain the analog audio input for the particular Source, select “Off” at the “Digital Audio” setting of the same “Source” menu.

VIDEO

There are four types of video input a particular Source could be assigned. These are HDMI, Component, S-Video and Video inputs. A fifth option is “Off” wherein the particular Source is prompted not to select any Video input.

Navigating through the Video input selections involve a combination of pressing [] and then [] to step through the selections. The following are the assignable Video inputs

HDMIHDMI 1, HDMI 2, HDMI 3, HDMI 4

Component VideoComponent 1, Component 2, Component 3 S-VideoS-Video 1, S-Video 2, S-Video 3, S-Video 4, S-Video 5, S-Video Front VideoVideo 1, Video 2, Video 3, Video 4, Video 5, Video Front

NOTE

An audio input and video input should always be associated to a selected Source setting to ensure audio and video output. If “Off” is selected for any of the Analog Audio, Video or Digital Audio settings, there will be no corresponding audio or video for the associated Source. For example, if the selected Video setting for a particular Source is HDMI 1 and both Digital and Analog Audio are set to “Off”, only video output will be available but no audio. Ideally, when the selected Video input is HDMI 1, it follows that the Digital Audio input is set to HDMI 1 or any of the digital inputs.
