3.6 Audio adjustments
There are three potentiometers and two pushbuttons on the DV-2000 MTS/LR system allowing
the user to tailor the BGM level, the audio output level and high frequency response. Refer to
the Quikey for location of each control.
Audio level
The level of the both 600 and 8 ohm Audio outputs are simultaneously adjusted using the
Audio level adjustment pot. Turning this potentiometer counter clockwise will lower the
Audio level. Turning this potentiometer clockwise will raise the Audio level.
Aphex®
A special, psycho-acoustical processing extends the high frequency response of the
DV-2000 MTS/LR. Turning this potentiometer counter clockwise attenuates the high
frequencies while turning it clockwise amplifies the high frequencies.
BGM In
This sets the overall level of the background music being fed into the DV-2000 MTS/LR.
Turning this potentiometer counter clockwise will lower the BGM level. Turning this
potentiometer clockwise will raise the BGM level.
BGM Fade
Two pushbuttons are provided on the top cover allowing the user to set the amount of
"ducking" to be applied to the BGM audio when a pre-recorded message is played by the
system. The BGM audio is mixed with the pre-recorded message audio, and this setting
governs the amount of BGM audio being mixed. "Ducking" is the amount which the BGM
audio level is attenuated, or lowered.
BGM Fade Down pushbutton – Black, momentary
Pressing this button will increase the ducking amount, or, in other words, lower the BGM
audio being mixed in with the audio output when a pre-recorded message is played.
Pressing the button one time will attenuate the BGM audio approximately 1dB. If the button
is pressed and held, the BGM level will be lowered approximately 8dB per second.
BGM Fade Up pushbutton – Black, momentary
Pressing this button will decrease the ducking amount, or, in other words, increase the
amount of BGM audio being mixed in with the audio output when a pre-recorded message
is played. Pressing the button one time will raise the BGM audio approximately 1dB. If the
button is pressed and held, the BGM level will be raised approximately 8dB per second.
3.7 Slide Switch descriptions
Several slide switches are provided on the top cover of the DV-2000 MTS/LR. These switches
control the functions described below:
Message Selection Switches
The DV-2000 MTS/LR system can record and play up to 20 messages. Each message has
a message selection switch associated with it. These switches allow the user to enable or
disable messages to be played, or recorded. The system will recognize changes of the
message selection switches during normal operation.
When a message selection is in the "ON" position, the message is enabled. When the
DV-2000 MTS/LR is in play mode, it looks at the switch for all recorded messages. If the
message is enabled, the system will play the message. When a message selection switch
is in the "OFF" position, the message is disabled. If the switch is disabled, the system will
skip the message.
When the DV-2000 MTS/LR is in record mode with Append/Replace mode active, the
system will overwrite any messages whose message selection switch is enabled, while
protecting the messages whose message selection switch is disabled. All message
