- Page 3 1. IntroductIon Congratulations on purchasing one of the world’s best bass amplifiers! Markbass amps are built to the highest standards by a small team of skilled technicians in San Giovanni Teatino, Italy. We have spent many years researching not only the highest-quality technologies for bass amp design and construction, but also the practical needs of the working bassist. The end result is a product that combines outstanding sound quality with intuitive features, attractive design and extreme reliability—all in one impossibly lightweight unit.
- Page 4 1.1 A Word from mArco de VIrgIlIIs When I began to develop the Markbass concept in Italy several years ago I had one objective in mind: to produce a top-quality bass amp that would meet the needs of profes- sional bass players everywhere. I wanted my amps to be compact and lightweight, yet able to handle the low frequencies that today’s four, five and six string passive and active basses are capable of producing.

3. tA501 Product oVerVIeW The Markbass TA501 is a high-quality bass amplifier with a tube compressor, a solid state preamp and an analog power amp, which delivers 500W of power into a 4 ohm cabinet (or two 8 ohm cabinets), or 300W into an 8 ohm cabinet. - Page 7 However, if and when equalization is required, you will find this amp’s EQ to be powerful and impressively detailed. The LOW EQ (7) control on the TA501 is set to a center frequency of 40 Hz. This means that it either boosts or cuts the volume of the frequencies around 40 Hz, to a maximum of 16 decibels.

The TA501’s optional footswitch has two on/off switches. One is a mute control that interrupts the output signal from your amp, but allows it through to a tuner, should you have one plugged into the rear panel. This is handy if you need to tune discreetly during live performances. The other switch bypasses your EQ and filter settings. Blue LEDs (6) (13) on the front panel illuminate when these switches are turned “on”. - Page 9 4. tA501 tecHnIcAl detAIls InPuts INPUT impedance: 500 Kohm, max. voltage: 9 Vpp RETURN EFFECT impedance: 33 Kohm, max. voltage: 12 Vpp controls GAIN –80 dB to +25 dB range COMPRESSOR RATIO min. 1:1 / max. ∞:1 LINE OUT level control on front panel...

The tube preamp includes one ECC81 tube and one ECC83 tube, both manufactured by JJ Electronics in the Slovak Republic.
- Page 13 If any one of these frequency ranges is neglected or poorly represented by your amp, you are not hearing an accurate representation of the sound that your bass is generating. Since the TA503 has been designed to give you clear, detailed and musical sound at all frequencies, when the amp is set “flat”-with all EQ knobs at 12 o’clock-you should hear a very true mirror of the sound of your bass. However, the following circumstances will require you to use equalization: The signal from your bass is lacking output level in one of the frequency ranges described above.
