GLA-55 harman/kardon

Features

Compatibility

• The GLA-55 speaker system is compatible with virtually any audio device with an analog output. A stereo mini jack connection allows

you to enjoy high-quality audio from a variety of devices such as MP3 and CD players, desktop computers (all platforms), satellite radio

and laptops.

Easy-to-use music controls

• Just a touch increases or decrease the volume. Touch both volume controls simultaneously to mute the audio output. Touch again to

unmute. An LED on the front of both satellites lets you know whether the system is on, on standby, or muted.

Beauty and sound

• The GLA-55 is a stylized multimedia focal point. Not just an exceptionally high-quality audio system, it’s also – from its chrome base to

its fully visible audio engine and port – a piece of art. No detail is left unreﬁned. The faceted cut-glass enclosures are a ﬁrst in desktop

audio systems, and will integrate beautifully with home and ofﬁce décor.

Digital power and DSP

• The GLA-55 system delivers with a powerfully tuned digital audio path. The clean and compact digital ampliﬁcation, coupled with

DSP (digital signal processing) equalization, efﬁciently provides GLA-55 transducers with cool-running power.

Subwoofer output

• The GLA-55 systems packs a powerful punch on its own but, for added bass response, the subwoofer output allows connection to most

stand-alone subwoofer systems.

Advanced technology

• GLA-55 speakers feature many proprietary technologies to provide the highest quality sound, including astonishing bass and clear,

accurate sound in any location.

• AtlasTM AL and CMMD®Transducers – The CMMD drivers provide accurate high frequencies but are also capable of low-frequency

extension to four octaves; the Atlas AL drivers are capable of nearly 1" peak-to-peak travel for tight, accurate bass reproduction. Their

pairing provides a full, rich frequency response from the lowest bass to the highest highs.

• Slipstream Port Design – The GLA-55 port minimizes boundary layer separation, providing high-output bass with low distortion.

• COE (Computer-Optimized Equalization) – The GLA-55 system equalization is computer-optimized to provide a rich, complete sound-

stage over a wide range of listening positions.

• OCT (Optimized Compression Topology) – GLA-55 speakers utilize a proprietary compression technology, which ensures clean,

accurate sound at high output levels.

•LED’s and Auto-ON feature:

The unit has an Auto-ON/Standby feature (like many of our other home

subwoofers)

The indicator is a white LED at the front of each loudspeaker

LED operation:

•Steady ON when the unit is powered up and receiving a signal (playing).

•LED’s slowly blink: STANDBY mode. (After approx.10 minutes of no signal)

•Mute function (press both volume buttons same time) the LED will be OFF. In

this state the speaker will not respond to an incoming signal (will not play

again unless it’s unmuted).

•Volume buttons/mute function (touch switch + and – buttons) in the MASTER

speaker above the woofer.

•The optional sub out jack is a 3.5mm stereo plug; this is a full range signal (not

low freq only, but intended only to be connected to powered subwoofers.)

•There is no main AC power switch
