The TC Electronic RH750 Class-D Bass Amplifier is designed for practice, studio, and live sound reinforcement applications. The amplifier has a compact form factor but can be placed in a standard 19" rack using an optional 19" bracket (sold separately). The unit provides 750W of class-D amplification at a minimum 4Ω load, as well as tone modeling, compression, 4-band equalization, and a tuner.

The front of the unit features a 1/4" instrument input for active or passive pickups. A gain knob allows you to adjust the input level, and bass, lo-mid, hi-mid, and treble knobs allows you to adjust the equalization of the signal. A shift button changes the function of each equalization knob from adjusting the gain -24/+15 dB to sweeping the center frequency from 71 to 1,120 Hz for the bass, 100 to 1,600 Hz for the low mid, 200 to 3,150 Hz for the high mid, and 400 to 6,300 Hz for the treble frequency range.

A SpectraComp knob controls the amount of spectral multiband compression applied to the low, mid, and high frequency bands. A tone knob can shift between TweeterTone mode for adjusting the high frequency content of the signal and a TubeTone mode for adding character to the sound that emulates tube amplification. A bank of three memory buttons allows you to set and recall parameter presets. An optional RC4 remote control footswitch (sold separately) can be connected for controlling these memory presets. A built-in LED tuner display allows you to fine tune your instrument. A master level knob controls the output of the amplifier.

The back of the unit features a 100 to 240 VAC power input, a combination Speakon and 1/4" output jack, a remote in jack for the optional footswitch, an 1/8" headphone out, a 96 kHz 24-bit AES/EBU digital XLR output, a rehearsal auxiliary in port and auxiliary out port for playing along with an MP3 player or other backing track, a set of insert preamp I/O ports for setting up effect loops, and a 3-pin XLR output for connecting to your speaker cabinet or stack.
