DSPEAKER SERVO 300 2 Quick Setup Guide 1. Servo 300 speakers can be placed close to the back wall or even corners, but make sure that there is at least 10 cm (4”) ventilation space behind the back plates of Servo 300 to allow sufficient ventilation. 2. Connect the linelevel (preout) input of the audio source to input connector. 3. Connect the included microphone into "ANTIMODE CALIBRATION MIC". connector and place the microphone into the listening position as accurately as possible. 4.
DSPEAKER SERVO 300 LISTENING ZONE 2.1 Placing the Servo 300 Speaker Servo 300 speaker is designed to be positioned close to the room walls and corners, where the response can be extended even as low as below 30Hz. However, safe distance of 10 cm (4 inches) to curtains or any other objects behind the speakers must be maintained to allow sufficient ventilation for the amplifiers. Do not place any flammable objects or materials near the amplified back plates.
DSPEAKER SERVO 300 2.2 Usage 2.2.1 Control Button The control button has different meanings in different situations, also depending on whether it is pressed briefly or pressed and held for longer period. All the operation functions are logical and intuitive: – Short press when the speaker is on will toggle the AntiMode correction ON (status led GREEN) and OFF (status led ORANGE). – Long press when the speaker is on and microphone connected will begin the AntiMode automatic room calibration process.
DSPEAKER SERVO 300 2.2.4 Automatic Wakeup and Standby The speaker will go to power saving “Stand By” mode deactivating it's power amplifiers when it has detected no input signal in 15 minutes. The speaker will also wake up automatically when it detects signal at the audio input. Wake up will take a few seconds as the power amplifiers must be turned on. When the speaker is detecting audio signal at the input in stand by and waking up, it will flash the led green once.
DSPEAKER SERVO 300 2.3 Errors and Warnings The speaker will monitor constantly it's input level, positional feedback of the woofer cone, currents of the amplifiers, operating temperature, status of the DSP and microphone input in calibration. The speaker can maintain safe operation in many different situations, but might inform the user about these. If electromagnetic pulse disorients the DSP, a special integrated “watchdog” will turn the power off instantly to prevent permanent damage or misbehaviour.
DSPEAKER SERVO 300 2.4 AntiModeTM: Automatic Room Correction The room response is one of the biggest influences in reproduction of sound, altering the tonal balance especially at the lower frequencies. In order to accomplish perfect sound characteristics in every circumstance, the active speaker should be able to measure the room and adjust itself to the existing acoustic conditions.
DSPEAKER SERVO 300 2.5 ASCM Calibration The speakers are incorporated with patent pending processor controlled Position Feedback measurement and Active Suspension Compliance Management System, ASCM. Thanks to the ASCM, the speaker will not suffer any common phenomena of uncontrolled low frequency energy storages, and will deliver the fastest, tightest and most accurate bass possible even to the lowest octaves inroom.
DSPEAKER SERVO 300 2.6 Output Gain Switch DSPeaker Servo 300 has three settings for different output levels. 0dB is the default setting, which is suitable for farfield dynamics. It gives the highest peak sound pressure level. However, it also has creates servofeedback which can sometimes result in higher noise level than desired for near field usage. 6dB will drop the output level by 6dB, which will result in lower noise level, but also decreased maximum sound pressure level.
