Frequently Asked Questions - 8350A GENELEC

How do I set up the 8350A without using the GLM software?

Set the STORED switch to OFF. Connect the mains and audio inputs (analog or digital). Use the DIP switches on the back panel to adjust tone controls (Bass Roll-Off, Bass Tilt, Treble Tilt, Desktop LF) and level. The monitor will operate with these manual settings.

What are the DIP switches on the back panel for?

The DIP switches control stand-alone functions: Treble Tilt (+2, -2, -4 dB above 5 kHz), Bass Tilt (-2, -4, -6 dB below 800 Hz), Bass Roll-Off (-2, -4, -6 dB near cutoff), Desktop LF (-4 dB at 160 Hz), ISS (enable/disable auto power saving), LED Disable (turn off front LED), Level (10 dB steps), Digital (select AES/EBU channel A, B, or sum), and Stored (use internal GLM settings).

How does the Intelligent Signal Sensing (ISS) power saving work?

When ISS is enabled via the DIP switch, the monitor enters a deep sleep state after 60 minutes (adjustable in GLM) with power consumption below 1 W. Upon detecting an input signal, it automatically wakes up to full operation. The front LED blinks green every 10 seconds when in ISS mode.

Can I connect the 8350A to a digital audio source?

Yes, use the AES/EBU digital input (XLR female). The monitor automatically selects the digital input when a valid signal is present. Supports sample rates 32-192 kHz and word lengths 16-24 bits. The digital output (XLR male) provides an unaltered copy for daisy-chaining up to four monitors.

What does the front panel LED indicate?

Solid green = normal operation; blinking green = GLM adjusting; green blink every 10 sec = ISS sleep; red blink = amplifier overload protection; solid red = muted; yellow = not in active group; yellow blinking = overheat protection.

How do I mount the 8350A on a stand?

The monitor includes an Iso-Pod table stand that allows tilting. For wall or ceiling mounting, use the two M6 x 10 mm threaded holes on the back (compatible with K&M mounts) or the M10 x 10 mm hole on the base (do not use for microphone stands). Ensure proper ventilation with at least 50 mm clearance.

What subwoofer is recommended for use with the 8350A?

Genelec recommends the 7300 series subwoofers for optimal system integration. For detailed configuration, use the Genelec Product Selection Tool at www.genelec.com.

How do I calibrate the 8350A with the GLM system?

Connect each monitor and subwoofer to the GLM network via RJ45 cables to the GLM Adapter, then connect to a computer via USB. Place the measurement microphone at the listening position. Download and install the GLM software from www.genelec.com, then follow the on-screen instructions to run AutoCal™ which adjusts equalization and alignment automatically.

What is the recommended placement for the 8350A monitors?

Place monitors symmetrically at equal distances from the listening position, with the acoustic axis pointing toward the listener. Avoid reflective surfaces near the monitors. For 5.1 setups, position left/right at 30° and surround at 110° from center. Use the tone controls to compensate for boundary effects (e.g., Desktop LF for table placement).

How should I clean the 8350A monitor?

The manual does not specify cleaning instructions. For general care, use a soft, dry cloth to remove dust. Do not use liquids or cleaners, and avoid exposing the monitor to moisture. No user serviceable parts inside.

USER MANUAL 8350A GENELEC

Introduction

Congratulations and a thank you for the purchase of this Genelec Smart Active Monitor (SAM) system. This manual addresses the stand-alone setup and use of the 8350A SAM monitor. These monitors can also be set up and used with the Genelec Loudspeaker Manager GLM ^™ and the proprietary Genelec monitor control network and software, offering much more versatile acoustic settings and features. Use with the GLM ^™ is described in the GLM ^™ System Operating Manual.

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.

The 8350A is suitable for professional monitoring tasks demanding high precision and reliability of monitoring. The Minimum Diffraction Enclosure ^TM (MDE ^TM ) and advanced Directivity Control Waveguide ^TM (DCW ^TM ) 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 (ISS ^TM ) 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 GLM™ Control Network

Although the 8350A can be used without the GLM ^™ software and control network, they only reach their full potential when set up and calibrated using the GLM ^™ software. Genelec Loudspeaker Manager GLM ^™ 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 GLM ^™ in the GLM ^™ System Operating Manual.

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.

Connect the MAINS INPUT to the mains supply. These products support any mains voltage globally (100-240 VAC, 50-60 Hz) so they can be plugged in anywhere. If the mains

power is provided with a generator, inverter or certain lower-quality 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 Manager™ (GLM™) 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 160Hz 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 (switches 3 and 4) offer three attenuation levels for the bass response below 800 Hz, usually

necessary when the monitors are placed near room boundaries. The attenuation levels are -2 dB, -4 dB and -6 dB.

Treble Tilt Control

Treble Tilt control allows adjusting the treble response above 5 kHz by +2 dB, -2 dB or -4 dB, which can be used for correcting an excessively bright or dull sounding system or to compensate for high frequency level loss if the monitor is placed behind a screen.

LED Disable

This switch shuts off the front panel LED light.

ISS

This switch activates or deactivates the ISS automatic power saving function. The default time for ISS activation is 60 minutes, but can be adjusted in GLM.

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/Decoupler™ (IsoPod™) 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.
