Product Overview

Alphanso Rock 22 is designed from the modern integrated circuitry. It’s a solid-state semiconductor amplifier. This one is able to handle 3 input signals at a time (two mono and one stereo). 22 watt is good enough for home practice with electric guitars or acoustic guitars or even mic, keyboard, electric drums, etc. Inside this combo amp, a 6 inch speaker has been mounted and that could divulge your guitar tone smoothly. Your guitar tone would be very bassy and sharp. Rock 22 amp has its own built-in overdrive effect with gain control; delay control, dedicated mic pre-amp, 2 band tone control that responses upto ±12dB, 2 stereo channels, and 15 watt external speaker out.

Description

 ① 1⁄4 inch Mono TRS Jack input. A maximum of 3m/10ft instrument cable needs to be used. Always use a low noise high quality cable to avoid unexpected hum. Gain control works in both clean and overdrive channels. The clean/OD switch is the clean or overdrive tone selection switch. The clean level is the volume control of the clean pre-amp channel and the OD level is for overdrive channel’s volume.

   The delay control works on the guitar channel only. You can easily bypass this effect just by the on/off switch. This knob controls how long it would take to repeat the sound (4ms to 720ms), and how many times the sound would feed into the signal; max 8 times at a same time.
    N.B. This is not reverb but delay. Reverberation and delay are two methods of signal processing that are often incorrectly equated. The confusion comes from the fact that they are so closely related. Reverb and delay aren’t completely unrelated effects — reverb can be thought of as a network of many short delays.

   Mic input channel is for any kind of acoustic instruments or balanced sound. This dedicated mic channel has volume level knob.
      N.B. Mic pre-amps are very much diverse than the guitar pre-amp. Its frequency response is much lower than the guitar input.

   Dual band equalizer control. It is an active equalize, so the response is huge. It is not suggested using its maximum power. The equalizer responses over ±10dB bass, and ±10dB treble. Follow the user manual’s recommendations. The on/off switch allows you to bypass the equalizer completely.

   Rock 22 has 2 x 3.5mm stereo channels. The left one can handle upto 1dBV (stereo) auxiliary input. The 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.

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

Additional information:
Power Switch: Rock 22 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.
