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 professional 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.
2. IMPORTANT SAFETY INSTRUCTIONS 1) Read these instructions; 2) Keep these instructions; 3) Heed all warnings; 4) Follow all instructions; 5) Do not use this apparatus near water; 6) Clean only with dry cloth; 7) Do not block any ventilation openings.
3. STUDIO PRE PRODUCT OVERVIEW The Markbass STUDIO PRE is a high-end, dual-channel preamp for bass, with both a solid-state preamp and a tube preamp. 3.1 STUDIO PRE FRONT PANEL 4 1 2 8 10 12 14 16 18 7 9 11 13 15 17 19 22 24 5 3 6 20 21 23 INPUT The input jack (1) accepts an unbalanced signal from your bass via a standard 1/4” instrument cable. CLEAN CHANNEL GAIN The GAIN (2) control determines how much signal is passed through the clean section of the preamp.
LOW frequencies constitute music’s sonic foundation—they give power to your sound, physically resonating your listeners’ bodies (and yours!), sometimes even causing people to move and dance! MIDs make your bass sound loud, projecting the sound over long distances, “filling the room,” and they convey the pitch of the notes that you play. Clarity of this range ensures that the melodies in your bass lines are heard. If detail is missing in this range, your melodic contribution to the music will suffer.
AMP CHANNEL COMPRESSOR The COMPRESSOR (5) switch engages a simple but professional compressor circuit, optimized for bass guitar, which allows you to control the dynamics of your sound. This is especially helpful when using distorted sounds. AMP 1, AMP 2, AMP 3 The AMP CHANNEL runs your signal in parallel through three signal paths (two tube-driven and one solid state) that can be engaged in whichever combination you want. The AMP 1 (8) signal passes through two ECC83S tubes for heavy tube distortion.
3.2 STUDIO PRE REAR PANEL 26 27 28 17 29 32 34 36 22 31 33 35 25 30 AMP CHANNEL OUT This balanced XLR (26) output allows you to send the AMP CHANNEL directly to a mixing console (either in recording or live situations) or soundcard (with XLR inputs) without the need of a DI box. Simply connect a standard XLR cable from this output to the soundboard/mixing console, or a snake connected to the board/console, or a soundcard XLR input.
FOOTSWITCH The STUDIO PRE’s optional footswitch has two on/off switches. One bypasses the AMP CHANNEL, removing any distortion you have added to your signal, as well as any equalization and filtering dialed on this channel. The other switches the PURE PARAMETRIC FILTER in the CLEAN CHANNEL on and off. Red LED (6) on the front panel illuminate when the footswitch (PPF) is activated.

7. STUDIO PRE 500 PRODUCT OVERVIEW The Markbass STUDIO PRE 500 is a high-end, dual-channel amplifier for bass, with both a solid-state preamp and a tube preamp, and with an analog power amp. 7.1 STUDIO PRE 500 FRONT PANEL 4 1 2 8 10 12 14 16 18 7 9 11 13 15 17 19 22 24 5 3 6 20 21 23 INPUT The input jack (1) accepts an unbalanced signal from your bass via a standard 1/4” instrument cable.

AMP CHANNEL COMPRESSOR The COMPRESSOR (5) switch engages a simple but professional compressor circuit, optimized for bass guitar, which allows you to control the dynamics of your sound. This is especially helpful when using distorted sounds. It can be switched on and off in real time. AMP 1, AMP 2, AMP 3 The AMP CHANNEL runs your signal in parallel through three signal paths (two tube-driven and one solid state) that can be engaged in whichever combination you want.
7.2 STUDIO PRE 500 REAR PANEL 26 25 27 28 29 30 33 35 37 32 34 36 1 + = SIGNAL 1 = GND 31 SPEAKER OUT The STUDIO PRE 500 can be connected to a speaker cabinets using either 1⁄4” speaker cables (do not use instrument cables) or speakon speaker cables. When using two cabinets, simply connect the second cabinet to the first cabinet. The high-quality Neutrik SPEAKON COMBO jack (26) is designed to accept either of these connection types.
EFFECT SEND AND RETURN If you use effect pedals or rack gear, you can route them through the SEND EFFECT (32) and RETURN EFFECT (34) jacks on the rear panel of the amp. The effects loop is wired in parallel with the CLEAN CHANNEL—this means that if something happens to your effects chain (a battery dies or a cable gives out, for example) while you’re playing, you will not lose your main signal. FOOTSWITCH The STUDIO PRE’s optional footswitch has two on/off switches.
