The Traynor YBA200

Thank you for choosing the Traynor YBA200 All-Tube Bass Amplifier. You are about to revisit one of the best quality-of-sound instrument amplifiers ever built.
The YBA200 is truly an evolution of technology and in true Traynor all tube tradition, no semiconductors are in the signal path. The YBA200 features capabilities such as a Resonance control, which adjusts the damping factor at the amplifier’s output stage (allowing the player to take full advantage of the tonal capabilities of instrument speaker cabinets). Modern technologies, such as specially designed toroidal transformers provide increased reliability and real vintage tube sound, without the heavy weight usually associated with vintage tube amplifiers. Bottom line, the YBA200 has real vintage tube sound, no compromises, and no excuses.

Features

• Two 12AX7 pre-amp tubes, a 12AU7 phase-splitter, and four KT88 power output tubes staying true to the all tube signal path Traynor philosophy. Class A/B amplification.
• Variable-range 3-band passive tone stack EQ with Scoop and Resonance Controls
• Unity gain, with a true balanced D.I./Line output. Selectable Pre-EQ or Post-EQ, –20 dB pad (and Ground Lift).
• Pre-Amp Out and Power Amp Input jacks. These jacks provide direct access to the YBA200’s signal chain so you may slave out, or slave into, another amp; or you can use these jacks as an effects loop (for professional-grade signal processing equipment).
• Tuner Out jack and Mute switch.
• Extremely lightweight due to specially designed toroidal transformers.

1. Power and Standby
   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 Inputs
   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 pick- ups, 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 sig-nal 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
   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 fre-quency 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.

10. Pre-Amp Out and Amp In
    The Pre-Amp Out and the Power Amp Input jacks provide versatility not usually associated with vintage tube amplifi-ers. The Pre-Amp Out jack can be used to slave another YBA200 or as an effects send. The Power Amp Input goes directly to the YBA200’s power amplifier, bypassing the pre-amp, which allows a perfect effects return. The Power Amp Input also lets the YBA200 be a true slave from another pre-amp.
    Note: The output signal of the Pre-Amp Out is set at 0 VU. When using the Pre-Amp Out as an effects loop it’s recommended to use professional-grade signal processing equipment (pedal effects might not have enough headroom).

11. Line Out XLR and Pre/Post
    The YBA200 is equipped with a unity gain, balanced D.I./Line output. You can select a direct, clean signal (Pre-EQ setting which delivers the sound directly to the Balanced Line Out) or tap the signal after the pre-amp (Post- EQ). Both signals are routed to the Balanced Line Out before the Master volume. A Ground Lift (lifts Pin 1 of the XLR) and –20 dB attenuation switch are also provided to help when routing signals directly to other equipment or mixing consoles.

12. Speaker Impedance Switch and Output
    Extension speaker cabinets are connected using the Speaker ¼-inch output jacks. Connections to these jacks are in parallel. Using the Speaker Load switch, the output of the YBA200 can be optimized to provide the rated full power (200 watts) for selected loads (8-ohms or 4-ohms).
    Note: As long as the total speaker load is not lower than 2-ohms, Speaker Load settings of 4-ohms or 8-ohms are interchangeable. Choose the setting that sounds best to you.

13. Tube Selection and Bias
    Your YBA200 is supplied with a set of factory-matched output tubes. When tube replacement becomes necessary, replace the output tubes with a matched set to maintain the highest performance of your amplifier.
    Note: When changing output tubes, a qualified technician should adjust the amplifier’s bias; readjusted for 40ma per tube (80 mV at the test points).
