BASSMASTER (YBA-1) OPERATING INSTRUCTIONS
GENERAL INSTRUCTIONS
l. Connect YBA-1 out put marked speaker to your speaker cabinet using the speaker cord supplied.
2. Plug power cord into wall outlet.
3. Make sure “on/off” switch is on.
4. Leave standby switch off for about one minute while tubes warm up, and the Bassmaster is ready for use.
USE OF THE FOUR INPUTS AND CONTROLS
1. The Bassmaster has two channels, each having two inputs.
2. The first channel is a bass channel (although rhythm guitar players often prefer it to the second channel) and is designed for bass. The lower input has more power than the upper input.
3. The second channel is more powerful and has a clearer sound. It is designed for guitar, the lower input is more powerful than the upper input.
4. Each channel has its own volume control.
5. When using the Bassmaster you may have noticed that while playing through one channel the other channel’s volume control affects the sound of the channel that you are using. This is a design feature and many interesting results may be obtained by experimenting with various settings.
6. The volume control of the channel being used should be turned up until a small amount of distortion is heard in the speakers and then turned slightly back. This is the optimum volume setting and the best projection will be obtained at this setting. Turning the amplifier up any louder will only result in the destruction of the speakers.
7. The treble control acts in the same manner as any other treble control and the same applies to the bass control.
8. Added features of the Bassmaster are the high and low range expanders. These control change the tonal colouring of the amplifier to such a wide extent that it makes the Bassmaster one of the most versatile amplifiers on the market today.
9. To adjust the four tone controls set them all to their mid position. Connect your instrument to the desired channel, and adjust the volume control for that channel (the other volume control should be left at zero).
10. Starting from left to right while playing adjust the treble, bass, low range expander, and high range expander. Experimentation will find the most pleasing setting.
11. Between sets leave the amplifier on “Standby”. The keeps the tubes warmed up and allows you to use the amp instantly by simply turning the standby on.
- NEVER TURN THE AMPLIFIER ON WITHOUT FIRST CHECKING TO SEE THAT THE SPEAKER IS CONNECTED CORRECTLY. SERIOUS DAMAGE MAY RESULT FROM IMPROPER USE.
The Bassmaster (YM-1) may be used with a variety of speakers Here are the recommended combinations;
l. YBA-1 with single fifteen inch speakers (YS-15). The design is used primarily for bass but may be used for guitar.
2. YBA-1 with single eighteen (YB-18A). This combination is excellent for bass guitar where a superb Bass sound is required.
3. YBA-1 with twin twelve (YT-12). A very biting sharp sound can be obtained from this speaker cabinet, It should be used with guitar only as bass will destroy the speakers. These speakers have so much treble sensitivity that a hissing sound may be heard when the treble controls are set at their extreme position.
4. YBA-1 with twin fifteen (YT-15). A very good deep bass sound can be achieved using this setup. It can be used for either bass or guitar. It has found limited use for the latter.
5. YBA-1 with four tens (YF-10). Less bass, but more punch is the result of using four tens, which is also suitable for either bass or guitar.
6. When using the YBA-1 with an extension speaker, the extension speaker should be the same as the main speaker cabinet. Mismatching cabinets may cause an imbalance in power distribution.
The Bassmaster amplifier was originally designed for bass players. Soon, however, guitar players started using it and because of this the high range expander circuit was included in the amplifier. The Traynor engineers work long hours to produce an amplifier which is suitable for both bass and guitar. Their results show in the superb quality of the Bassmaster.
