Dayton Audio B652 Speaker User Manual


 
Thank you for choosing Dayton Audio. Dayton Audio loudspeakers are designed
to provide exceptional performance and maximum value. Please read on to
discover how to get the most from your new speakers.
CONNECTING YOUR LOUDSPEAKERS
Use good quality wire for the connection between your Dayton Audio
loudspeakers and the amplifier. For distances up to 10 feet, conventional “speaker
wire” or lamp cord is acceptable. For longer runs, heavier wire should be used.
For proper performance the speakers must be “phased” correctly. To insure proper
phasing, connect the red speaker terminals to the red amplifier terminals and the
black speaker terminals to the black amplifier terminals. All two-conductor wire is
marked in some way to help you do this. One side will be marked with a colored
stripe, a raised rib, or a different colored conductor. Use the marked side for the
“red” connections.
ROOM PLACEMENT
Because of their well-behaved off-axis response and excellent dispersion, your
new Dayton Audio speakers are less critical to position than most loudspeakers.
Often, simply placing them where they best fit into the decorating scheme is all
that is necessary for exceptional performance.
If you are inclined to go through a more rigorous positioning exercise, the
following paragraphs will help you achieve all the performance that your system is
capable of.
Carefully select a few recordings. Choose recordings made with simple
miking and strong vocals by a single performer. Avoid recordings with piano
accompaniment unless you know that the recording microphones were at least 15-
20 feet from the piano. The reason for this precaution is that the piano is a large
instrument, and is often recorded with multiple microphones placed close to it.
The notes arrive at the microphones from different directions and the speakers will
reproduce the directional clues confusing the positioning process. Physically small
sound sources localize much more precisely. Horns, strings, vocals, and drums
snap into place with the loudspeakers are optimally positioned.
Front without grill Side Back Front
Start with the speakers directly in front of your primary listening position. Avoid
hard vertical edges within 3 or 4 feet of either side of the cabinet. Position the
cabinets about 1-2 feet out from the wall. Listen to one of the selected recordings
paying close attention to the positions of the instruments and vocalist. Move the
speakers a few inches at a time, returning to the listening position to evaluate the
results. Once placement is optimized, the vocalist will be firmly positioned in front
of the instruments and the instruments will seem to be between or behind the
loudspeakers. During the design of most Dayton Audio speakers’ performance is
optimized for listener location 10-12 feet in front of the tweeter. If possible, position
your speakers to that when you are seated in the primary listening position your
ears are 10-12 feet from the tweeter. Viewed from your seat, the angle between
the speakers should be 30 to 60 degrees. Pay special attention to the bass. The
relation between bass response and room position is critical. Tightly localized high
and low pressure spots result from reflections off the room boundaries. Moving
one or both of the loudspeakers just a few inches will rearrange thousands of
hot and dead spots all over the room. The secret to proper positioning is to keep
the wort of these spots from falling on the primary listening position. Position the
speakers so that the bass levels are in proper perspective to the rest of the musical
spectrum. Listen to several recordings to that you hear bass from a variety of
instruments. The most common positioning error involves getting the bass level
right for one note, but not for others.
Loudspeaker positioning can be time consuming, but the rewards justify the effort.
CABINET CARE
The finish of your speakers can be maintained and enhanced by periodic use of
a surface protection such as “ArmorAll”. The grilles may be vacuumed or gently
tapped or brushed to remove dust and debris.
POWER RATINGS
Almost any speaker can be used successfully with almost any amplifier.
Conversely, almost any speaker can be damaged by almost any amplifier-despite
either unit’s power rating. The power recommendations that we publish are
accurate only if our assumptions concerning the amplifier, the type of music,
and the conditions of use are correct. Most importantly we assume that the
volume never is set above the point of distortion. Distortion is an indication that
the amplifier or loudspeaker is operating beyond its design limits. If you hear
distortion, immediately reduce the volume. Damage can occur within seconds.
Do not ignore distortion just because the volume control is not all the way up. A
common misconception exists that amplifier power is proportional to the setting of
the volume control with maximum setting necessary for full power output. This is
rarely the case. Most amplifiers deliver full power when the volume control is set
somewhere in the middle of its range. Use of loudness, bass boost, treble boost,
or an equalizer can produce full output at even lower knob settings. Distortion is
the only clue that damage is imminent.
Dayton Audio loudspeakers are designed to reproduce music and speech in
a home environment at moderate volume levels. When used within their limits
Dayton Audio loudspeakers will provide many years of trouble free performance.
