Operation

USING THE L70

You may operate the L70 DVD Surround Sound Receiver from its front panel or via the HTR L70 remote control. Since the remote will be the primary controller for most cases, we will focus on remote-controlled operations. Be sure also to read the section, “Front Panel” above.

SELECTING SOURCES

With the HTR L70’s remote’s “Amp” device selected, the remote’s numeric-key section directly selects the receiver’s internal DVD and tuner “TUNER”, as well as the other inputs and multichannel input (“Ext. 5.1”) refer to the orange labels directly above each key.

When a source other than the internal DVD is selected, the video signal at the monitor output is always a black background, until the internal DVD is selected.

When you change sources, the VFL will display the new input in its primary display.

ADJUSTING THE VOLUME

Use the HTR L70 remote’s <Volume up/down> keys to adjust the “master volume” of the L70, raising or lower all channels together.

NOTE

A momentary keypress will change the master volume by 1 unit increments; if you hold down <Volume up/down> the master-volume change will “run-on” until the key is released.

The L70’s OSD will show the volume setting as a line graphic with a numeric display above relative to the reference level.

Since recordings vary considerably in overall average level, there is no imperative to listen at any particular master-volume setting. A setting of 20 may sound “as loud” from one CD or DVD as 10 does from another.

If muting has been activated (below), adjusting master-volume via the HTR L70 remote or the front- panel knob automatically releases the mute function.

The L70 will power-up from standby mode at whatever master volume setting was last used; however, if the prior setting was greater than 50 the L70 will power up to 50. This prevents inadvertently beginning a session at excessive volume.

MUTING THE SOUND

Use the HTR L70 remote’s <Mute> key to silence all channels completely. Muting is always available, regardless of source or SURROUND MODE selections.

NOTE

Cycling through standby or powering off releases muting; the L70 will return from standby with muting off if standby was invoked with muting on.

A changing input or listening-mode selection releases muting.

Adjusting the master-volume via the HTR L70 or the front-panel knob automatically releases the mute function.
