AN EXTREMELY IMPORTANT NOTE ON HR824 BASS RESPONSE AND YOUR CONTROL ROOM.

Your new HR824s achievetheir best bass response ina room that’s optimized forbass reproduction. A lot of

factors can conspire to thwart the HR824s’ extended low frequency — including room shape, room volume and acoustical treatment.

This is not a cop-out or an apology. It’s plain old physics in action. Luckily we’ve armed you with some compensating controls which you can use to optimize the frequency response of the speakers in your particular room. Consider the following:

The ACOUSTIC SPACE switch must be set correctly.

When you put your HR824s in a corner or up against walls, their bass characteristics change. Adjust the ACOUSTIC SPACE switch setting accordingly to avoid muddy or exaggerated low frequency response.

Feel free to experiment.

In many respects, every control room is unique in terms of its acoustics.

Even after you’ve read about how to set the HR824’s rear panel switches, try other settings to see if your particular room environment requires different adjustments.

And, even after you’ve placed your monitors where you think they’ll sound best, try moving them around. You might be pleasantly surprised.

Finally, keep an open mind about improving your room’s acoustics and bass-handling ability.

Nobody likes to buy a new set of monitor speakers and then be told that they should spend extra bucks on bass traps or a remodeling job. But the simple fact is, “standard” rooms, i.e. rectangular rooms in conventional business or residential structures, are rarely if ever conducive to optimal low bass reproduction without some modifications.

Luckily, there are plenty of options short of building a new control room, many of which are covered in this manual.

Additional Tidbits of Wisdom

•When you shut down your equipment, turn off the HR824 studio monitors first to prevent thumps and other noises generated by any upstream equipment from coming out the speakers. When powering up, turn on the monitors last.

•Save the shipping box! You may need it someday, and you don’t want to have to pay for another one.

•Save your sales receipt in a safe place.

•Also record both HR824 serial numbers in the space provided on the inside front cover, along with where and when you bought them.

Placement

The HR824s were designed to be placed in a vertical position. If you find it necessary to place the speakers in a horizontal position (on their sides), place them so that the woofers are toward the inside; that is, so the woofers are closest to each other. This provides the best low-frequency summing and overall imaging.
