CBS/ARBITER

CBS/Arbiter market two ranges of amplifiers, the Fenders and the Arbiters. Within these two ranges, any buyer ought to be able to find what he's looking for.

Chief among the Fender 100 watt amps is the Dual Showman Reverb. A "piggyback" amp, it sports 2 channels, normal and vibrato, with four instrument inputs, a separate bright switch in each channel, separate volume, treble, bass and middle controls in each channel, as well as a master volume control, built in reverb and vibrato, and vibrato speed and intensity controls, all this atop two 15" speakers mounted in specially designed baffles. The Quad Reverb amp boasts most of the advantages of the Showman, except that it offers four 12" speakers.

The Super Six Reverb is also basically the same amp, but as its name implies, it sports six speakers, each 10 inches in size.

The Vibrosonic Reverb is really designed with steel and jazz guitarists in mind, who require a wide range and balanced response.

It has one specially designed wide range 15" Fender Professional Series Speaker, and its power output and specifications are much the same as the above-mentioned Fenders.

There is a third input for a linked channel and when both channels are operating at full volume, overload can be obtained with use of the master volume control.

CMI also do a 100 watt combination amplifier, which is the same power unit as the above-mentioned amp, coupled with two 12 inch speakers. CMI do not recommend its use with bass guitars.

HH ELECTRONICS

HH manufacture three amps which fall into our category. The IC 100 and the IC 100S are identical in size, weight and power output, but their other differences are important. The IC-100 offers two channels; the first supplies volume for both normal and bright inputs, presence, treble, bass, vibrato, speed and depth control, a reverberation switch with master reverb control and a sustain switch, the second channel also has all of these with the exception of the vibrato, speed and depth controls, but it offers foot switches for reverb/tremelo and sustain.

The IC-100S also offering two channels, offers bright and normal input volume controls, presence and treble controls, a sustain switch and control with high or low level sustain effect. A footswitch for remote switching is supplied. Channel two has volume for normal and bright input, and presence, treble and bass control.

HH's TPA 100D is a silicon transistor amp designed for broadcast and recording, or any audio amplification where high quality sound reproduction is vital. It is D.C. coupled throughout, and has a wide band width, a good deal of negative feedback to ensure stability into loads of any impedance characteristic. The unit is protected from the load mismatch and short circuits by a dissipation limiting circuit.

HORNBY SKEWES

Miles Platting are the Hornby Skewes range of amps, and their V100 is the amp which falls into our 100 watt category. A valve amp, the V100 is versatile, as it is equally suitable for use with lead, bass, organ or general PA systems.

The DC300A power amp is widely used in vibration and shaking applications as well as in applications requiring high current pulses or complex waveforms. It has an unusually wide power bandwidth that makes it useful for driving totally reactive loads.

The D150 power amp is a lower powered model, but its power out rating is 100 watts RMS at 8 ohms. It boasts the same low distortion as the DC300A power amp, and can drive any amp no matter how reactive.

ROSE-MORRIS

Marshall is the best known name in the world of amplification and it should surprise no-one that Rose-Morris market everything in the 100 watt range that a musician could want.

It was only recently that Marshall introduced solid-state amps (see our Soundcheck in our March issue) and after eight years, the new bass and lead amps have attracted, understandably, a good deal of attention.

The lead 100 boasts a front panel with master input and volume control combining both channels and a treble boost switch for overdrive and distortion effects. The back panel has a slave output, a direct injection output for feeding a mixing desk and an echo socket. The bass 100 has all these advantages save treble boost and studio switch. The Marshall sound was founded on valve amplifiers, and the models which helped to make the sound are the 1959 lead and the 1992 bass amps. Both of these have four inputs (two per channel), individual volume control for high, treble and normal inputs, presence, bass, middle and treble controls are common to both channels.

Marshall's 2078 100 watt transistorised lead combo marries the above-mentioned Marshall transistorised amp with a cabinet housing 4 x 12 in. speakers, while the 2077 100 watt bass combo marries the transistorised bass amp with speakers of the same size as those in the lead combo, but specially designed for bass use.
