ADJUSTING LEVEL TRIM “ON THE FLY”
You can make changes to the relative levels of centre, surround, and subwoofer outputs. This may prove
useful in a number of circumstances; for example, to increase (or tone down) a film’s dialog level by raising
(lowering) the centre channel, or to reduce excessive deep bass (or enhance deep bass) by lowering
(raising) the subwoofer level without having to go into the LEVEL TRIM OSD menu.
TO ADJUST LEVEL TRIM
Use the HTR L70 remote’s “SURR”, “CENTER”, and “SUB” keys for direct-access level adjustment of
these channels, over a range of ±10 dB. You can also adjust all channel levels using the front panel’s
navigation keys (see “Front Panel,” above), or via the <LEVEL TRIM> line of the OSD’s <MAIN MENU> screen.
NOTE
• The surround channels (if any) adjust in tandem. Channel Level changes made via the HTR L70 are
retained even if you cycle the receiver through standby.
• Level settings are added/subtracted to the setup levels established by the L70 level-calibration routine,
invoked by the HTR L70 “Test” key.
ADJUSTING THE TONE CONTROLS
The L70 bass and treble controls are adjusted using the front panel’s TONE button in conjunction with the
VOLUME knob; see “Front Panel,” above.
NOTE
Bass/treble settings affect only the front left/right channels, and are active in all SURROUND MODEs.
ABOUT THE 12 V TRIGGER OUT
The L70’s rear-panel 12 V TRIGGER OUT is a convenient method of controlling on and off any auxiliary
equipment that is connected to or is used in conjunction with the L70, when the L70 is turned on or to
standby via remote or the front panel power button.
12 V TRIGGER OUT
The L70’s rear-panel 12 V TRIGGER OUT is a female miniature 3.5 mm stereotype jack that will produce +12
V DC at approximately 50 mA. Use a 3.5 mm stereotype miniature phone plug with the centre pin + 12 V
and the first band the ground. We recommend that you use a good quality cable with shield when attaching
the 3.5 mm stereotype plug so as to prevent false triggering of the auxiliary equipment due to electro-
magnetic interference from nearby electronic equipment. See your NAD audio specialist for more information.
