Operating Manual 8260A, 8351A, 8250A and 8240A
Introduction Congratulations and a thank-you for the purchase of this Genelec SAM system. All Genelec SAM systems are designed to integrate easily into the digital production environment. There are several ways to configure and operate SAM systems for a wide variety of high quality audio applications. The SAM monitors also have analog inputs, making them versatile and intelligent replacements for standard analog monitors.

The location of the acoustic axis is on the centerline of the monitor at the given height “h”. The acoustic axis of the 8351A and 8260A is located at the center of the coaxial driver. m Min 5 c Max 60 cm Figure 4.
Minimise Reflections Acoustic reflections from objects close to the monitors like desks, cabinets, computer monitors etc. can cause unwanted colouration and blurring of the sound image. These can be minimised by placing the monitor clear of reflective surfaces. For instance, putting the monitors on stands behind and above the mixing console usually gives a better result than placing them on the meter bridge.

• Run AutoCal and review the results to check for large dips at or above 85 Hz. Move the monitors and repeat AutoCal if there is a problem. • Press “Finish”, then in the Main Page select “Menu | Store Acoustic Settings to All Online Monitors” and close GLM. • For each SAM monitor, turn it off, select “Stored” on the back of each monitor to activate the internal Acoustic Settings, and then turn it on again.
