The Peavey Special 112 is a solid state guitar amplifier that enables you to adjust gain, equalisation, voicing, and even add reverb to your guitar's sound. There are many amps on the market, so it's worth comparing specifications on various amps before making a purchase. The Special 112's layout will be instantly familiar to anyone who's used a Peavey amp.
Rated Power & Load
The Peavey Special 112 delivers 160 watts of RMS power into 4 ohms. It can also be clipped at 100 watts into 8 ohms, but it is not recommended to use the amplifier with 2 ohms. "Ohms" is a measurement of the amp's opposition to the flow of the electrical current.
The Special 112 consumes 500 watts of power, at 50/60Hz, and from a 120V AC adaptor.
Pre-Amp: High Gain Input
The amplifier has two separate inputs, one for "High Gain" and one for "Low Gain." Most electric guitars would need to use the "High Gain" input, which gives you 220K ohms of impedance, and a maximum input level of +10dBv and 3V RMS. The minimum input level you can have is -34dBv and 20mV RMS.
Pre-Amp: Low Gain Input
This input is used for instruments with especially high output levels. As such, it has 44K ohms impedance. It can take an input of up to +16dBv and 6V RMS. The minimum you can put into it is -28dBv with a 40mV RMS.
Effects Send and Return
The "Effects Send" and "Effects Return" jacks operate at an input and output level of -10dBv and 0.3V RMS. The impedance when sending is a thousand ohms and when receiving can be up to 22K.
Hum and Noise
The Special 112 omits a noise (with the nominal input level) at 80dB below the unit's rated power.
As well as the standard "Low," "Middle" and "High" dials, the Special 112 features a "Presence" knob and a push button for "Bright." The "Presence" dial can alter the sound by 15dB in either direction, and transmits at 5KHz. The push-button for "Bright" adds 6dB and operates at 2KHz.
You can connect external footswitches to the Special 112 that can silence the "Reverb" effect and the lead channel. These both have to be selected and active for the pedals to have a function, but this means that you can stop any unwanted noise instantly.
