Facilité d'utilisation
Unplug by grasping the plug rather than pulling on the cord. • Be careful not to place heavy objects on the power cord. • Avoid using this unit in very high or low temperature locations. Also keep away from heaters and coolers since this type of equipment will affect circuit and pitch stability. • Avoid using this unit in very dusty or humid places. • If it is necessary to use this unit in an area with neon or fluorescent lights, keep it as far away from these lights as possible since they will induce high levels of noise. Sometimes changing the angle of this unit in relation to the lights will help reduce noise. • When connecting this unit, plug the cord into the external amplifier first, then plug the other end of the cord into the SIP-300 output. To disconnect, remove the cord from the SIP-300 first, then from the amplifier. • To clean this unit, wipe with a cloth dampened with a neutral cleanser. Do not use solvents such as paint thinner.

After making connections, set the front panel controls as shown in the drawing. 2. Turn on the POWER switch ©. 3. Raise the VOLUME control ® and the MASTER VOLUME ©to obtain the normal quitar sound. 4. Try various settings of the OVERDRIVE and TONE CREATOR section controls. DISTORTION SECTION Distortion is produced by the overdrive circuit and also by the output amplifier stage (see "LEVEL SECTION'', p. 4). The amont of distortion is controlled by the SENSITIVITY control © and the LEVEL SECTION VOLUME control Soft Distortion This setting produces soft distortion much like that produced by vacuum tube amplifiers. Hard Distortion This setting can be used when playing harmonics or when using feedback. NAMES AND FUNCTIONS OF THE CONTROLS INPUT SECTION INPUT Jack©,© Use the HI GAIN INPUT ©with low output level instruments and the LO GAIN INPUT © with high output level instruments. VOLUME 1 © Controls the amount of overdrive. VOLUME 2 Q This controls the output level from the OVERDRIVE SECTION. FOOT SWITCH Jack© For remote ON/OFF control of the overdrive effect using. a foot pedal (Roland FS-1; sold separately). OVERDRIVE INDICATOR © Operates in conjunction with the FOOT SWITCH jack ©.above to indicate when the overdrive effect is ON. TONE CREATOR SECTION BASS © MIDDLE® and TREBLE © Controls For adjusting the bass, middle, and high frequency ranges. Turn clockwise to accent the respective frequency ranges. FREQUENCY RANGE SELECTOR Switches © , © , © Selects the frequency cutoff points for the BASS©, MIDDLE©, and TREBLE © controls. BASS: HI =50Hz, LO=40Hz MIDDLE: 1kHz,500Hz TREBLE: HI=9kHz, L0 = 6kHz LO CUT FILTER Switch © At ON, cuts all frequencies below 60Hz at — 12dB/oct. Prevents speaker damage from undesireable high level low frequencies and eliminates low frequency noise. HI CUT FILTER Switch© At ON, cuts high frequencies above 6 kHz at — 12dB/oct. Removes undesireable high frequencies and high frequency noise form the output. LEVEL SECTION 1 The SIP-300 is equipped wi.th»an output amplifier stage. The VOLUME control ©controls the input level to this output stage while the MASTER VOLUME control ©controls the output level of the SIP-300. Distortion can be created in this stage by setting the VOLUME control © high and the MASTER VOLUME control © low. The MASTER VOLUME control © does not affect the output level at the balanced output
