Product Overview

Alphanso Martina 10 has been designed from the modern integrated circuitry. This one is solid state semiconductor amplifier. Martina 10 is able to handle 2 input signals at a time (one mono and one stereo). 20watt is enough for small size room practice with electric basses (recommanded) or acoustic basses, with backtracks. Inside this combo amp a 8 inch speaker has been installed and that could bring out very sharp bass tones. Martina 10 amp has its own built-in 3 band tone control that responses upto ± 10dB, individual active/passive pre-amps. 15watt external speaker output.

Description :

 ❶ 1⁄4 inch Mono TRS Jack input. A maximum 3m/10ft instrument cable need to be used. Always use a low noise high quality cable to avoid unexpected hum.

 ❷ Active and Passive pre-amp switch. It would let you choose whether you are using an active or passive bass.

 ❸ This volume control works on the clean channel for both active and passive basses, and also on the overdrive channel for both active and passive pre-amps. N.B. pre-amp volume level should be as same as the maters volume.

 ❹ 3 band equalizer control. It’s an active equalizer, so the response is huge. It is not recommended to use in its maximum power. The equalizer responses upto ±10dB on bass, mid and treble. Follow the user manual’s recommendations.

 ❺ Martina 10 has 2 x 3.5mm stereo channels. The left one can handle upto 1dBV (stereo) auxiliary input. Volume of auxiliary input needs to control from the source. The right one delivers sound to headphones or recording input and can deliver upto 450mW to 45Ω load.

 ❻ This is master volume which controls the main power amplifier’s sound, that means it works for speaker only. It won’t effect on headphone output. N.B. pre-amp volume level should be as same as the maters volume.

Additional information:
Power Switch: Martina 10 has a power switch with a red light indicator.
Back panel:
Power Socket: The power cable is removable from the amp and would be needed to change in case of damage. Inside the power socket there is a fuse, which is also removable. (You need to change the fuse in case of damage.)
Speaker Out: There is a 15 watt speaker output. This is an external speaker system, so you can power up any speaker cabinet you want, when the main inner speaker will cut off.
