Monaural inputs are converted from a single point sound source into a sound which fills the entire stereo field. The Dimension D gives a new dimension without the apparent movement of sound produced by most other chorus devices. CONNECTION • Both balanced and unbalanced inputs and outputs for ease of use in the studio or on the stage. • Click-free noisless switching between four different dimension modes. • Remote controlled dimension EFFECT/NORMAL function. • Fast acting LED level indicators. • Low noise (S/N greater than 95d8, "A" weighted). • Standard 19" rack mount. • Make sure that the line voltage in your area meets the reguirements given in the specifications. • Check with your local Roland dealer if you want to use the SDD-3?Q in a foreign country. • Plug the SDD-320 in before turning on the power switch. PRECAUTIONS • Do not open this unit. • Unplug this unit when it is not to be used for long periods of time. 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 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 m 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 theSDD-320 output. To disconnect, remove the cord from theSDD-320 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. MONO INPUT PEDAL SWITCH DP-2 OPERATION © © 0 0 1. After making the connections, set the INPUT MODE switch @ (rear panel) as needed. Set both the BYPASS switch O and the DIMENSION MODE ©at OFF. 2. Turn on the POWER switch ©and check that the pilot light above goes on. 3. Adjust the level of the external sound source so that the OUTPUT LEVEL INDICATOR © reads close to "0". • Using levels which drive the LEVEL INDICATOR ©above "0” can cause distortion. Using levels which cause the LEVEL INDICATOR ©to read below "0” will increase the noise level m the output signal. 4. Select the desired DIMENSION MODE© NAMES AND FUNCTION OF CONTROLS BYPASS Switch© The BYPASS switch© makes direct connections between the inputs and outputs. This means that the POWER switch ©may be left OFF when the SDD-320 is in the BYPASS mode. DIMENSION MODE Selectors © Selects the dimension mode, MODE 1 produces the softest effect; MODE 4 produces the strongest effect. At OFF, the sound passes through the SDD-320 without change. REMOTE Jack© For remote switching between the OFF mode and the DIMENSION MODE using a foot switch (Roland FS-1 or DP-2; sold separately). To use, select a DIMENSION MODE ©and use the foot switch to switch between the selected mode and normal sound. • As an example of use: With an organ as the input sound, play a porgcession of block chords and use the foot switch so that some of the chords are "straight" and others are "Dimension D" chords. If the Roland DP-2 Pedal Switch is used, instant changes can be made even in very rapid passages. The DIMENSION MODE is in effect with (he DP-2 depressed and OFF (normal sound) when released. EFFECT INDICATOR© Lights when the DIMENSION MODE is in effect. • Works with both the REMOTE jack ©and the DIMENSION MODE selectors © , OUTPUT LEVEL INDICATOR © Shows combined output level. (OdB indication - +4dBm output). • This indicator does not work when the BYPASS switch © is ON (BYPASS MODE). POWER Switch © with pilot lamp Note: If balanced inputs are used, use balanced outputs and vice versa. Do not use balanced outputs when using unbalanced inputs, or unbalanced outputs when using balanced inputs. INPUT MODE Switch (A) Selects the input mode. At MONO, left input is disconnected and right input serves both dimension channels. INPUT Connectors B Balanced inputs (13kfl; max. input: + 14dBm). Pin assignments: Pin 1: shield (ground) Pin 2: cold Pin 3: hot INPUT Jacks £ Unbalanced inputs (26kfi; max. input: -f 14dBm). • Do not use the balanced and unbalanced outputs simultaneously. OUTPUT Connectors D Balanced output (600fl; nom. level: + 4dBm). Pin assignments same as INPUT connectors © OUTPUT Jacks § Unbalanced output (6000; nom, level: + 4dBm). • Do not use balanced and unbalanced outputs simultaneously.
