GENELEC 8320A Studio Monitors and Subwoofers

GENELEC 8320A Studio Monitors and Subwoofers logo

General Description

Genelec 8320A and 8330A are two-way smart active monitors designed for demanding professional applications.
Genelec Smart Active Monitor™ (SAM™) digital signal processing (DSP) built inside each smart active monitor with Genelec Loudspeaker Manager™ (GLM™) software provides unparalleled acoustic quality, ease of use, and high monitoring accuracy even in difficult acoustic environments. The high performance drivers are directly connected to dedicated D Class power amplifiers. System protection is implemented as a part of the SAM signal processing.
The MDE™ (Minimum Diffraction Enclosure™) enclosure is made of die-cast aluminium and shaped to reduce edge diffraction. Combined with the advanced Directivity Control WaveguideTM (DCWTM), this design contributes to the excellent acoustic neutrality.

Delivery Contents

Each monitor is supplied with a mains cable, 5 meter RJ45 cable, and an operating manual.

Connections

Before connecting, switch off the monitors and the signal source. Once all the connections have been made, the monitors can be switched on.

Mains Power

The power switch is located on the back panel (see Figure 2). Connect the monitor to a mains socket having a protective earthed connection. Do not connect to an unearthed mains supply or using an unearthed mains cable. These monitors feature an universal mains voltage and can be connected to any voltage between 100-240 VAC 50-60 Hz.

GLM Network Connection

Up to 30 monitors and subwoofers can be connected to a computer using the GLM Adapter. An RJ45 cable is supplied for this. Start control network cabling from the GLM Adapter to the first monitor. Continue daisy-chaining to all monitors and subwoofers (see Figure 3). No special sequence is necessary. GENELEC 8320A Studio Monitors and Subwoofers

Analog Audio Input

The analog audio input on both models accepts a balanced male XLR connector.

Digital Audio Input

The 8330A digital audio input (DIGITAL IN) accepts a male XLR connector carrying an AES/EBU formatted digital audio signal. The digital audio can be routed to the next monitor or subwoofer using an XLR output (DIGITAL OUT). The AES/EBU digital audio subframe A or B is selected using the GLM software.

Settings and Acoustic Calibration

The Smart Active Monitors are extremely flexible in compensating the acoustic influences of the room and support automated setup using the GLM User Kit and software. The 8320A and 8330A are compatible with GLM 2.0 and later.
The GLM software can be downloaded from Genelec web site (www.genelec.com/glm). The GLM 2.0 User Kit is needed for the setup. The User Kit contains the GLM Adapter and GLM measurement microphone.
The GLM Adapter is connected to the computer USB port and the GLM network. The GLM measurement microphone is placed at the listening location.
Execute the setup process in the GLM software to align and set up the Smart Active Monitors and Subwoofers as a system. After calibration, keep the computer connected to maintain the settings or save the settings to the Smart Active Monitors using the GLM software.

ISSTM AutoStart Function

Intelligent Signal Sensing (ISSTM) enables very low standby power consumption, less than 0.5 watts.
As a factory default, the ISS function is disabled. The ISS function can be enabled by clicking the “ISS Power Saving” pulldown menu in the GLM software. This menu also provides a selection of the time before entering standby. The playback resumes once an input signal is detected. There is a slight delay before playback resumes.

Mounting Considerations

Align the Monitors Correctly

Place and point the monitors so that their acoustic axes are aimed towards the listening
position. Vertical orientation is preferred, as this minimizes the sound colour change around the crossover frequency when the listener is moving horizontally.

Maintain Symmetry

Place the monitors at an equal distance from the listening position and symmetrically relative to the room walls. Place the listening position on the room front-back centerline and the monitors at an equal distance from this centerline.

Minimize Reflections

Acoustic reflections are created by objects close to the monitors. Such objects can be desks, cabinets, computer monitors etc. Acoustic reflections can cause unwanted sound colorations and sound image instability. These can be minimised by placing the monitors and the listening position clear of reflective surfaces.

Minimum Clearances

Sufficient clearance for amplifier cooling and reflex port function must be ensured. The surroundings of the monitor must be open to the listening room with a minimum clearance of 3 centimeters (13/16 in) behind, above, and on both sides of the monitor. The ambient temperature may not rise above 35 degrees Celsius (95°F.)

Mounting Options

The Genelec 8320A and 8330A offer several mounting options: The Iso-Pod™ (Isolation Positioner/Decouple™) vibration insulating stand allows tilting of the monitor to correctly align the acoustic axis. The bottom of the monitor has a 3/8 in UNC threaded hole compatible with a standard microphone stand. The rear has two M6 x 10 mm threaded inserts for wall or ceiling mount brackets. Genelec offers a wide variety of mounting accessories. Please consult Genelec web site or your nearest Genelec dealer.

Maintenance

No user serviceable parts are inside the monitor. Maintenance and repair must only be undertaken by qualified service personnel.

Safety Considerations

The 8320A and 8330A have been designed in accordance with international safety standards. The following warnings and cautions must be observed to ensure safe operation and to maintain the monitor under safe operating conditions:

Servicing must only be performed by qualified service personnel. The monitor must not be opened.
Do not use the monitor with an unearthed mains cable or an unearthed mains connection.
Do not expose the monitor to water or moisture. Do not place any objects filled with liquid, such as vases, on the monitor or near it.
This monitor is capable of producing sound pressure levels in excess of 85 dB, which may cause permanent hearing damage.
Free flow of air behind the monitor is necessary to maintain sufficient cooling. Do not obstruct airflow around the monitor.
The device is not completely disconnected from the AC mains service unless the mains power cord is detached from the device or the mains outlet.

This product is guaranteed for a period of two years against faults in materials or workmanship.
Refer to supplier for full sales and guarantee terms.

Compliance to FCC Rules

This device complies with part 15 of the FCC Rules.
Operation is subject to the following two conditions:
This device may not cause harmful interference, and this device must accept any interference received, including interference that may cause undesired operation.
Note:
