Traynor YBA200 Mode D'emploi page 4

1. The Power and Standby Toggle Switches
Due to the nature of vacuum tubes, we suggest the YBA200 be powered up for a few
minutes prior to using. This will allow the tubes to warm up. The pilot light glows red when the
amplifier is engaged; it glows amber when in Standby mode.
Note: Before powering up and disengaging the Standby switch make sure speaker cabinets
are connected to the output jacks.
When the amplifier is warmed up, disengage the Standby switch and get ready to
experience the classic tone of a Traynor Bassmaster All-Tube Amplifier.
Note: It's also recommended to leave the amplifier powered up during set breaks, The Standby
switch cuts all outputs from the preamp and power amplifier.
2. 0dB / Passive and -6dB / Active Input Jacks
The YBA200 is equipped with 2 input jacks. The 0 dB/Passive input feeds the first tube input-
stage directly while the –6 dB/Active input applies a pad to it. The –6 dB input is usually used
for bass guitars that have active pickups, or extremely hot levels.
3. Tuner Output & Mute
The YBA200 features a ¼-inch Tuner Output jack to enable direct connection with a tuner without
affecting the signal path into your amplifier. When the switch is depressed the Tuner Out jack
receives signal while the power amplifier and the D.I./Line Output are muted. This allows you to tune
your instrument without affecting the sound going to the speaker cabinet, control board or PA.
4. Gain Control
The Gain control is placed immediately after the first tube-stage and is used in conjunction with
the Master volume control to help achieve the proper sound and feel. This control also allows the
capability of giving a warm overdriven tube sound when turned up (even at low volume levels).
5. 3-Band Equalization and Range Control
The YBA200 features a vintage passive tone stack consisting of traditional Treble, Bass and
Mid Controls. Additionally, the tone stack is equipped with a Range control; this adjusts the
frequency range for the Treble, Bass and Mid controls.
Tech Note: The YBA200 has been fitted with a traditional passive tone stack. This allows the
tubes to generate natural sounding harmonics when driven into saturation. Active tone controls
can generate unwanted harmonics when clipping interrupts the feedback loop in the amplifier.
Passive tone controls are always subtractive, which means they can only reduce the gain in
their specific frequency ranges. Active tone controls, on the other-hand, are wrapped around
an amplifier and will provide gain boost when the controls are turned past the middle position.
6. Bright Switch
The Bright switch provides a small amount of treble boost for added presence.
7. Scoop Switch and Control
The YBA200 is equipped with a defeatable Scoop control to help accentuate deep bass and
treble frequencies. Maximum midrange scoop is achieved by turning the control fully clockwise.
8. Resonance Control
The Resonance control is placed on the output stage of the power amplifier and controls the
amount of low frequency damping. Setting the control clockwise reduces the damping factor
and allows the resonance of the speaker cabinet to be more pronounced.
Note: Setting the control counter-clockwise will increase the damping factor and
produce a tighter sound.
9. Master Volume
The Master control adjusts the overall output level of the amplifier. The level being sent to
the Balanced Line Output is not affected allowing the signal at the mixing console to be
unaffected by adjustments during performance.
