SAFETY PRECAUTIONS
The following check should be performed for the continued
protection of the customer and service technician.
protection of the customer and service technician.
LEAKAGE CURRENT CHECK
Measure leakage current to a known earth ground (water
pipe, conduit, etc.) by connecting a leakage current tester
between the earth ground and all exposed metal parts of the
appliance (input/output terminals, screwheads, metal
overlays, control shaft, etc.). Plug the AC line cord of the
appliance directly into a 120V AC 60Hz outlet and turn the
AC power switch on. Any current measured must not exceed
o.5mA.

DOLBY DIGITAL
Available only with digital input sources encoded with Dolby Digital data. It provides up to
five separate main audio channels and a special dedicated Low Frequency Effects channel.

DOLBY DIGITAL EX
Available when the receiver is configured for 6.1/7.1 channel operation, Dolby Digital EX is the
latest version of Dolby Digital. When used with movies or other programs that have special
encoding, Dolby Digital EX reproduces specially encoded soundtracks so that a full 6.1/7.1
soundfield is available. When the receiver is set for 6.1/7.1 operation and a Dolby Digital signal is
present, the EX mode is automatically selected. Even if specific EX encoding is not available to
provide the additional channel, the special algorithms will derive a 6.1/7.1 output.

Exclusive to Harman Kardon for AV receivers, Logic 7 is an advanced mode that extracts the

material. Depending on the number of speakers in use and the selection made in the
SURROUND
SELECT
menu, the “5.1” versions of Logic 7 modes are available when the 5.1 option is chosen,
while the “7.1” versions of Logic 7 produce a full sound field presentation, including back surround
speakers when the “6.1/7.1” option is chosen. The Logic 7 C (or Cinema) mode should be used
with any source that contains Dolby Surround or similar matrix encoding. Logic 7 C delivers
increased center-channel intelligibility, and more accurate placement of sounds with fades and pans
that are much smoother and more realistic than with former decoding techniques. The Logic 7 M or
Music mode should be used with analog or PCM stereo sources. Logic 7 M enhances the listening
experience by presenting a wider front soundstage and greater rear ambience. Both Logic 7 modes
also direct low-frequency information to the subwoofer (if installed and configured) to deliver
maximum bass impact. The Logic 7 E (or Enhance) mode is an extension of the Logic 7 modes that is
primarily used with musical programs and is available with the 5.1 surround mode option selected
only. Logic 7 E adds additional bass enhancement that circulates low frequencies in the 40Hz to 120Hz
range to the front and surround speakers to deliver a less localized soundstage that appears broader
and wider than when the subwoofer is the sole source of bass energy.
