• A power rating of at least 100 W, impedance of 4 – 8 .. For the DG80-210A/DG80-112A The amp’s internal speaker (8 .) is connected to the SPEAKER 1 jack. The SPEAKER 2 (EXT) jack can be used to add an external speaker(s). Also, if necessary, you can disconnect the internal speaker to connect 2 external speakers directly to the amp. The two speaker jacks are connected in parallel. When external speakers are used, make sure the speakers meet the following requirements. When one speaker jack is used. • A power rating of at least 100 W, impedance of 4 – 16 .. • The total impedance for the speakers in a circuit must not be less than 4 .. When both speaker jacks are used. • Speakers connected to each jack must have a power rating of at least 100 W, and impedance of 8 – 16 .. • The total impedance for the speakers in a circuit must not be less than 4 .. For the DG130HA The amp is equipped with two speaker jacks. The two speaker jacks are connected in parallel. Make sure the speakers meet the following requirements. When one speaker jack is used. • Power rating of at least 130 W, impedance of 4 – 16 .. • The total impedance for the speakers in a circuit must not be less than 4 .. When both speaker jacks are used. • Speakers connected to each jack must have a power rating of at least 100 W, and impedance of 8 – 16 .. • The total impedance for the speakers in a circuit must not be less than 4 .. Total Impedance If two or more speakers are to be connected, you must take into consideration the total impedance of the speakers. Speakers normally have an impedance of 4, 8 or 16 .. When two or more speakers are used together, the total impedance will change according to the manner in which the speakers are connected. Connecting in a series The total impedance equals the impedance of the 1st speaker + 2nd speaker + 3rd speaker + … When three speakers are connected in a series, as shown below, the total impedance will be 24 .. Connecting in a parallel series The total impedance = When three speakers are connected in a parallel series, as shown below, the total impedance will be about 2.7 .. For the DG80-210A/DG80-112A The two speaker jacks are connected in a parallel circuit internally therefore, adding a 4 . external speaker to the 8 . internal speaker results in a total impedance of 2 .. In order to maintain a minimum impedance of 4 ., an 8 . speaker or greater must be used as an external speaker. External Speaker Greater that 8 . Internal Speaker 8 . DG100-212A/DG80-210A/DG80-112A/DG130HA DG100-212A/DG80-210A/DG80-112A/DG130HA r First, achieve sound output 1. With the DG amplifier’s power switched OFF, connect your guitar to the INPUT jack on the front panel.To start with, try using the LOW jack. 2. With the OUTPUT knob set to “0”, switch the power ON. 3. As a starting point, set the TRIM level to “5” and strum the guitar. Then, gradually raise the OUTPUT level. 4. Once you have sound output, proceed to set the TRIM level as described in the following section. Adjust the TRIM level The TRIM level allows you to set the output level of the guitar to an optimum level that matches the DG amplifier’s INPUT jack. With a well adjusted TRIM level, subtle picking nuances and the attack of a strong strum can be clearly heard. An improperly adjusted trim level will result in noise, feedback, and/or a cut up sound. * The output level between guitars does vary. Whenever you switch guitars, it will be necessary to readjust the trim level to match the guitar. * HIGH and LOW input levels are different. Even if the same guitar is used, make sure the TRIM level is readjusted whenever a different input jack is used. * Even when creating distortion, make sure that the TRIM level is properly adjusted, and use the GAIN control to produce distortion. 1. Set the guitar’s volume to its maximum level and powerfully strum the guitar. Begin to adjust the TRIM level. An optimum level is achieved when the Green LED is lit. 2. Continue rotating the TRIM knob to the right, so long as the Red LED does not light. Set the TRIM level to “10” if the Red LED does not light. * If the Red LED still does not light, lower the TRIM level, connect the guitar to the HIGH input jack and repeat the previous procedure. Sound Settings Choose one of the DG amplifier’s eight preset amp types, then use the GAIN+MASTER, and tone controls to shape the guitar’s sound. 1. Choose an amp type using one of the AMP SELECT buttons. The selected amp type button’s LED will light. 2. Use the GAIN, MASTER, and the five tone controls to shape the guitar’s sound. HINT OUTPUT knob and MASTER knob Turning either knob will change the volume. The MASTER knob controls the preamp’s master volume. This setting is stored in memory. The OUTPUT knob controls the power amp’s volume. This setting is not stored in memory. Volume levels for individual memory settings should be set with the MASTER knob. The speaker’s output level should be controlled with the OUTPUT knob. * When an AMP SELE...
