User manual YAMAHA WT11E

[. . . ] The SV250/255 features a dual pickup design using one piezo-electric pickup located underneath the bridge to reproduce the rich acoustic tone produced by the overall instrument, and another newly developed piezoelectric pickup built into the bridge to accurately reproduce subtle bowing nuances. Output from the two pickups can be blended freely to create a wide range of tone. The instrument's electronics are housed in a sturdy aluminum control box that can be placed on the floor or attached to the player's apparel with its integral belt clip. The unit supplies the violin's preamp with its needed electric power and incorporates an equalizer for shaping the tone of the instrument's audio signal. [. . . ] · Strong vibration. Handling and Transport · Never apply excessive force to the controls, connectors or other parts. · Always unplug cables by gripping the plug firmly, not by pulling on the cable. · Disconnect all cables before moving the unit. · Physical shocks caused by dropping, bumping, or placing heavy objects on the unit can result in scratches and more serious damage. Power Supply · Turn the power switch OFF when not in use. · If you use an AC power adaptor, unplug the adaptor from the AC outlet if not to be used for an extended period of time. · Unplug the AC power adaptor during electric storms. · Avoid plugging the AC power adaptor into the same AC outlet as appliances with high power consumption, such as electric heaters or ovens. Also avoid using multi-plug adaptors since these can result in reduced sound quality and possibly damage. Cleaning · Clean the cabinet and panel with a dry soft cloth. · A slightly damp cloth may be used to remove stubborn grime and dirt. · Never use cleaners such as alcohol or thinner. · Avoid placing vinyl objects on top of the unit (vinyl can stick to and discolor the surface). Electrical Interference · This unit contains electric circuitry and may cause interference if placed too close to radio or television receivers. · Do not listen for extended periods of time at loud volume levels using the inner earphones or headphones. Doing so can result in damage to your hearing. r Line Out Jack (Unbalanced) (LINE OUT) The line out jack is compatible with a standard ¼" phone plug. The signal is delivered from this output after being adjusted with the volume, treble, and bass controls. t Line Out Jack (Balanced) (BALANCED OUT) The balanced output jack is compatible with an XLR connector. This jack delivers a balanced signal that is the same as the LINE OUT jack (adjusted with volume, treble, and bass controls). The signal can be attenuated by 26dB using the BALANCED OUT PAD switch on the side of the control box. Caution · Make sure that the power is switched OFF or all volume levels are set to "0" on all external equipment before connecting external equipment to the Line Out Jack (Unbalanced, Balanced). Loud volume levels can damage your hearing, and damage equipment. · When making connections to external devices, make sure that the proper plugs are used and securely connected. · If the sound is distorted, use the volume control on the instrument or on the Control Box and lower the volume until the sound is no longer distorted. 8 [Control Section Details] <On the Instrument> y Pickup Blend Control (PICKUP BLEND) Controls the volume balance between the two built-in pickups. The line out jack is compatible with a standard ¼" phone plug. Rotate the knob fully to the right [BODY] to produce the signal from the pickup underneath the bridge, which reproduces the rich tone produced by the instrument's body. [. . . ] · When changing or adjusting strings, do not put your face close to the instrument. The string may suddenly break resulting in eye or other unexpected injuries. 4th string G D A E Groove 1st string SV250 G C D A E Groove 5th string 1st string Caution SV255 [Looking from the tailpiece] · The lower side of the bridge supports the 1st string (E), the higher side supports the 4th string (G)/5th string (C).
