Description :

 ❶ 1⁄4 inch Mono TRS Jack input. A maximum 5m/16ft 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 is the selector switch between clean and overdrive. This pre-amp switch works on both passive and active channels.

 ❹ This gain 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. Gain control needs to set at 50% maximum should work for most of the bass guitars.

 ❺ 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.

 ❻ 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.

 ❼ This is the compressor pre-amp, has an excellent compression range. Threshold and sustain, both works with this single knob.

 ❽ Martina 14 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.

 ❾ 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 14 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.)
Send/Return: These send-return sockets are for external effects. Remember that after connecting the send socket the amp won’t work unless you connect the return jack back.
