Using Calibrate Mode
Figure 11
The Auditioner® Playback
System III LED display
When the Sound Pressure Level that you hear from the Auditioner playback system matches
the level of the original signal that you recorded, you have a "calibrated" signal. When you
play pre-recorded material from an analog source on the Auditioner playback system, you
need to take a series of steps (see below) to ensure that the level you hear is correctly
calibrated.
When the Auditioner playback system is connected to a digitally-transmitted signal, the
calibration is automatic. It is possible for your digital recording to lose calibration if you use
an analog playback device. Although the file itself will not lose calibration (because it is
digital), the audio device that you use (such as a portable CD player) might cause the
calibration to be lost. We recommend that you playback all digital files from the hard drive of
your computer using the USB connection to avoid losing calibration. If you must use an
analog CD player, we recommend that you record the provided calibration tone onto the CD
when you record your audio. The calibration tone can be found on the Bose
®
Modeler® Plus
software product CD.
Note: The calibration display has a push button switch that provides a way to toggle between
Sound Pressure Level and calibration readings. The “up” position is calibrate mode, the
“down” position activates the SPL meter. For information on monitoring the Sound Pressure
Levels, see “Monitoring Sound Pressure Levels” on page 12.
Follow these steps to calibrate the Auditioner playback system when using an analog
playback device:
1. In the Bose
®
Modeler® Plus software, record your audio to the hard drive as a .wav file.
2. Record your .wav file to a normal audio CD. When you record the CD, you should include
the calibration tone file located on the Bose
®
Modeler® Plus software product CD. You
should record this calibration tone as the first track on the CD.

Note: The Sound Pressure Level meter in the Bose® Modeler® Plus software always shows
the average Sound Pressure Level that would be measured with a bare microphone at the
active listener position in the absence of any background noise.
Auditioner playback system can mix together 2 additional analog sound sources into the
playback audio (using the RCA line-in and the 3.5 mm stereo line-in). This is useful for
situations such as adding in background noise in addition to the program material. When you
mix in additional sources, the Sound Pressure Level meter on the Auditioner playback system
will display the combined sound pressure level of the source material plus the additional
analog sources. Please note that the Sound Pressure Level meter in the Bose
®
Modeler® Plus
software only displays the level of the source material. It will not take into account the
additional analog sources that are input into the Auditioner playback system. In summary:
Follow these steps to monitor the Sound Pressure Level using Auditioner playback system.
1. Connect Auditioner playback system to a Windows XP PC running Bose
®
Modeler® Plus
software, or connect Auditioner playback system to an external audio device. See “Con-
necting Auditioner® Playback System III to a PC” on page 10 or “Connecting an audio
device to Auditioner® Playback System III” on page 12.
2. With an audio source selected, choose a particular listener location in the Bose
®
Mod-
eler
®
Plus software and play the sound system simulation.
3. Monitor the Sound Pressure Levels on the Auditioner playback system and adjust the
source level in the Bose
®
Modeler® Plus software.
See Table 1 on page 14 for the correlation between the LED display and actual Sound
Pressure Level values. The Sound Pressure Level values represent an averaged level over a
100 ms time constant. Each LED lights and stays lit when the average sound has exceeded
its dB SPL value.
For example, the first yellow LED lights when the average Sound Pressure Level exceeds 85
dB SPL over a 100 ms time constant. This LED (and all green LEDs below it) is lit while the
average Sound Pressure Level is below 90 dB SPL. When the average Sound Pressure Level
exceeds 90 dB SPL the second yellow LED will become lit (and all the green and one yellow
LED are lit).
If you have: Bose

tem III
This section describes how to connect a CD player to the Auditioner playback system. If you
wish to use Auditioner playback system with a CD player as your audio source, you will first
need to record a CD with the audio output from the Bose
®
Modeler® Plus software. You can
then connect a CD player to the Auditioner playback system using the steps below. Using
the Auditioner playback system calibration feature it is possible to play this recording back at
a calibrated level. (See “Using Calibrate Mode” on page 14)
To connect a CD player to the Auditioner playback system follow these steps:
1. Connect one end of the 3.5 mm stereo cable to the 3.5 mm line-in on the back of Audi-
tioner playback system.
2. Connect the other end to the headphone jack on the portable CD player.
Note: The line-in input will boost the signal from the CD player by +20 dB.
Monitoring Sound Pressure Levels
Figure 10
The Auditioner® Playback
System III LED display
During Auditioner playback system operation you can monitor the Sound Pressure Level
(SPL) by checking the Sound Pressure Level meter. To view the Sound Pressure Level meter,
make sure that the Auditioner playback system is not in Calibrate mode. The Calibrate
button is in the “up” position in Calibrate mode, and in the “down” position to activate the
Sound Pressure Level meter. An array of ten rectangular LEDs display the average operating
Sound Pressure Level of the system.
Note: The clip light indicator will illuminate whenever the hardware experiences an internal
overload condition. The clip LED closely relates to the physical limitations of the hardware at
different frequencies. If the clip light illuminates, turn down the source level or use different
program material.
There are two places you can view Sound Pressure Level data: in the Bose
®
Modeler® Plus
software, and on the Sound Pressure Level meter located on the Auditioner playback system.
These two Sound Pressure Level meters will generally show the same levels during a listening
session, however there may be a small difference due to the Playback EQ that is applied by
the Auditioner playback system.

The On/Off switch is located on the back of the Auditioner playback system. Press the
switch into the On position to turn the unit on. If the unit does not power on, make sure it is
plugged in.
Note: The Auditioner playback system has been designed to work only with the Bose
®
Modeler
®
Plus software. Although it is possible to connect Auditioner playback system as a
standard USB audio device, or as an analog audio device, any signal that Auditioner playback
system receives would not be equalized for the playback system. As a result, the audio signal
will be spectrally and spatially incorrect.

Auditioner® Playback System III USB connection
Auditioner playback system is a standard Microsoft Windows USB 1.0 compliant audio
device. Auditioner playback system works as a USB 1.0 device when using USB 2.0. The
Auditioner playback system connects like any other USB device that you add to your
computer and it appears as an additional sound card.
Whenever you connect a USB device, the computer's host controller polls certain information
from the device, and then decides if there is enough bandwidth available to add the device. If
there is enough bandwidth, the host controller adds the device. If there is not enough
bandwidth, you will need to disconnect one or more of your other USB devices (such as a
USB printer) to make more bandwidth available for the Auditioner playback system. We
recommend that you only have one active sound device connected to your computer at a
time. If you do experience a conflict, it is likely that you are using a similar USB chip (for
example, USB bus-powered speakers) on your network. To resolve this problem, simply
unplug the other USB device(s).
There should be no audio dropouts over your USB network. Once the Auditioner playback
system is connected and accepted by the host controller, there will be sufficient bandwidth to
pass audio to the USB device. Streaming audio will always take precedence over other USB
traffic such as a USB mouse or USB printer.
If you do not have enough open USB ports on your computer, you may want to use a USB
hub to provide more ports. You can buy any off-the-shelf USB hub. We have tested USB 1.0
and 2.0 compliant hubs from D-Link, Belkin, Targus, and IOGEAR, and have found them to be
reliable. Connect the USB hub to your computer, then connect the Auditioner playback
system and other USB devices to the hub. For more information on using a USB hub, see
“Connecting Auditioner® Playback System III to a USB hub” on page 10.
Note: When using a USB hub, you may experience a slight latency due to network traffic. As
the latency is very short, this should not have an impact on your Auditioner playback system
listening session.
After you connect the Auditioner playback system to your Windows laptop (or other device)
you can monitor the connection by checking the USB activity lights on the back of the
Auditioner playback system system. When there is activity, the green LED illuminates. When
the connection is in standby mode, the red LED illuminates.
