Product Information: Genelec Smart Active Monitor 8350A

The Genelec Smart Active Monitor (SAM) system is a
high-precision and reliable monitoring device suitable for
professional monitoring tasks. It is equipped with Minimum
Diffraction EnclosureTM (MDETM) and advanced Directivity Control
WaveguideTM (DCWTM) technologies to provide excellent frequency
balance even in difficult acoustic environments. The SAM system can
integrate easily into all professional environments, supporting
both standard analog line level audio and AES/EBU formatted digital
audio signals. The SAM system is also equipped with Intelligent
Signal Sensing (ISSTM) technology that automatically puts the
monitor into a deep sleep state where it consumes less than one
Watt of power. Upon sensing an input signal, the monitor wakes up
to full operation.

Product Usage Instructions:

To set up the SAM system, follow the steps below:

System Setup using GLMTM Control Network:

Figure 1 shows the GLM control network cabling. The setup is

All Genelec SAM systems are designed to integrate easily into all professional environments, supporting both standard analog line level audio and AES/EBU formatted digital audio signals.

LISTENING POSITION

The 8350A is suitable for professional monitoring tasks demanding high precision and reliability of monitoring. The Minimum Diffraction EnclosureTM (MDETM) and advanced Directivity Control WaveguideTM (DCWTM) technologies provide excellent frequency balance even in difficult acoustic environments.
Each monitor is supplied with a mains cable, one 5 m GLM network cable and an operating manual.
Energy saving Intelligent Signal Sensing (ISSTM) can be turned on to put the monitor automatically into a deep sleep state where the product consumes less than one Watt of power. Upon sensing an input signal the monitor automatically wakes up to full operation. The wait until entering the ISS power save can be configured using the GLM software. When the ISS is active you can have your monitoring system ready for action at all times.
System setup using GLMTM Control Network
Although the 8350A can be used without the GLMTM software and control network, they only reach their full potential when set up and calibrated using the GLMTM software. Genelec Loudspeaker Manager GLMTM and the proprietary Genelec monitor control network and software offer automated acoustic equalization and alignment for any reproduction system from simple stereo to very complex 3D immersive audio setups including also one or more subwoofers. GLM setup is fast and accurate. The settings can be controlled with a computer or be permanently stored in the monitors to make the setup available at all times even when a computer is not in use. Genelec recommends setting up SAM monitoring systems using GLM. You can find a detailed description of the setup and the use of GLMTM in the GLMTM System Operating Manual.

Figure 1. GLM control network cabling
The setup is fast and consists of the following steps:
· Connect a CAT5 (RJ45) cable between each monitor (and subwoofer) and finally to the control network input of the GLM Adapter device (see Figure 1).
· Connect the GLM Adapter device to computer USB connector.
· Using a microphone stand, place the Genelec measurement microphone at the listening location with the microphone pointing upwards and the microphone top at the height of the engineer’s ear. The microphone is a part of the GLM User Kit.
· Connect the microphone cable to the microphone input in the GLM Adapter device.
· Download the GLM software at the Genelec web site (www. genelec.com).
· Install the GLM software and follow the instructions in the software to measure and set up your monitors.
· If you plan to not use a computer for controlling the monitors, use the GLM software to write the setting into the monitors (use menu item “Store | Store the Current Group Settings…”).
While the GLM network is disconnected the settings stored using the Genelec Loudspeaker Manager software can be selected in use by setting the STORED switch ON.
Setup without using the GLM
When GLM is not available, you can use the settings on the monitor for system setup. These settings are limited but provide the basic acoustical calibrations and input selection. To use this method, set the STORED switch OFF.

power is provided with a generator, inverter or certain lowerquality UPS devices, we recommend filtering of the mains power voltage harmonics and taking care that the voltage supply is stable.
The ANALOG IN connector is used for analog audio signals. The maximum input level is +25 dBu. These monitors produce 100 dB SPL sound level at 1 meter in free space for an analogue input signal of -6 dBu.
The DIGITAL IN AES/EBU female XLR connector is for AES/ EBU formatted digital audio input signals. This input is selected automatically when a valid digital audio signal is present. Analog input is selected when the AES/EBU signal input is disconnected. The AES/EBU input supports two channels in a single cable). When the digital source device controls the digital output level, it may be advantageous to lower the level on the monitor’s controls, which will enable the use of a higher digital signal level with more digital resolution. With digital inputs the audio is referenced to 0 dBFS (dB relative to the digital full scale, the largest level that can be represented in the AES/EBU signal). These monitors produce 100 dB SPL sound level at 1 meter in free space for a digital input signal of 30 dBFS. The DIGITAL OUT male XLR carries an unaltered copy of the digital signal fed into the digital in connector. This enables daisy-chaining up to four monitors.
The CONTROL NETWORK RJ-45 connectors are used with Genelec Loudspeaker ManagerTM (GLMTM) network. These connectors are not Ethernet LAN compatible. Do not connect to Ethernet LAN.

Stand-Alone Control Functions
Bass Roll-Off Control
Bass Roll-Off control attenuates the monitor’s output near the cut-off frequency. Attenuation levels of -2 dB, -4 dB or -6 dB (both switches ON) can be selected.
Desktop 160 Hz
The desktop low frequency control (switch 5) attenuates the bass frequencies around 160 Hz by 4 dB. This feature is designed to compensate for the boost often occurring at this frequency range when the monitor is placed upon a meter bridge, table or similar reflective surface.
Bass Tilt Control
The Bass Tilt control switches (swiches 3 and 4) offer three attenuation levels for the bass response below 800 Hz, usually

Table 2. Monitor front panel light indications summary

Digital
The Digital switch selects the digital audio channels on the AES/EBU. Turning both switches on reproduces the sum of the A and B channels. A 6 dB of attenuation is applied to avoid overloading the monitor. If the AES/EBU cable is operated in dual-wire mode, the monitor detects this automatically and the channel selection switches have no effect.
Level
The Level switches scale down the monitor output level in 10 dB steps. The effects of these switches add up and combine with the effect of the rotary level adjustment control. The combined total setting range is 42 dB.
Stored
Stored switch selects the use of the controls on the monitor’s back panel or the settings stored inside the monitor memory using the GLM system calibration software. Setting the Stored switch to OFF position selects the settings defined by the monitor’s own controls. Setting the Stored switch to ON position selects the use of internally stored GLM settings. Using the Stored option overrides all adjustments done with the monitor’s own controls.

Operating Environment
These monitors are designed for indoor use only. The permissible ambient temperature is 15-35 degrees Celsius (50-95°F) and relative humidity 20% to 80% (non-condensing). When the product has been stored or transported in cool environment and is taken into a warm room, wait 0.5-1 hours before opening any packing to prevent condensation of humidity before connecting to mains power. Sufficient cooling must be ensured. The minimum clearance is 50 mm (2 in) behind, above and on both sides of the monitor. The space must be ventilated sufficiently to dissipate the heat.

Mounting and Placing Monitors
Mounting Options
The vibration insulating Isolation Positioner/DecouplerTM (IsoPodTM) table stand allows tilting of the monitor for correct alignment of the acoustic axis. The stand can be attached to three points on the enclosure, allowing vertical and two horizontal positions. Aim the monitor so that its acoustic axis point towards the listening position (see Figure 3). Vertical orientation is preferable, as this eliminates acoustical cancellation problems around the crossover frequency. Place the monitors symmetrically at equal distances from the listening position. If possible, place the listening position on the left-right centerline of the room (see Figure 4). When a monitor far away (1 to 2.2 m, 3-7 ft) from the acoustically hard wall behind the monitor, an acoustic reflection from the wall may cause cancellation of low frequencies and reduce bass output.
Acoustic reflections from objects like desks, cabinets, computer monitors etc. can cause unwanted colouration and blurring of the sound image. Minimise these by placing the monitors away from acoustically reflective surfaces. Putting the monitors on stands behind and above a mixing console usually improves the response over placing monitors on a meter bridge. Symmetrical positioning of the sound reflecting objects maintains a balanced soundstage (see Figure 4).
A wide variety of ceiling and wall mounts are available through your Genelec dealer. The 8350A can be fitted with König & Meyer monitor mounts using two M6 x 10 mm threaded holes on the enclosure back. There is an M10 x 10 mm threaded hole in the base of the monitor. Do not use this thread for mounting the monitor on a microphone stand. Monitor stands typically have an incompatible 3/8″ UNC thread. A wide selection of accessories is available for Genelec monitors. Consult the Genelec Accessories Catalogue at www.genelec. com or your local distributor/dealer for information.
Front Panel Light
Normally, the light on the front panel is green, indicating normal operational mode. Red and yellow colours are used to indicate special situations. See Table 2 above.
Use with Subwoofers
Genelec recommends using the 7300 series subwoofers. For more detailed system configuration and matching products, please consult the on-line Genelec Product Selection Tool at www.genelec.com.
Maintenance
There are no user serviceable parts inside the monitor. Maintenance or repair must only be done by a Genelec certified service.
