Aphex's Easyrider Technology is combination of three exclusive Aphex circuits: the Wave Dependent
Compressor, a patented circuit which automatically adjusts compressor time constants according to program complexity: our No-Knee compression
curve circuitry which automatically adjusts compression ratio: and our own proprietary Aphex 1001 Class A VCA. This is the identical VCA that
we use as the heart of the Aphex Compellor leveler/compressor and the Aphex Dominator peak limiter, well known by recording and mastering professionals.
One of the most annoying aspects of conventional compressors is the audible "pumping" or
"breathing" side effects heard when the signal exceeds the compressor threshold and the compression "kicks-in". No-Knee compression
curve means there is no abrupt transition to a high compression ratio. The Aphex Easyrider' delivers ultrasmooth compression, even under heavy
gain reduction that makes most other compressors unlistenable. Under any condition, the Aphex Easyrider Model 108 sounds great and delivers studio
quality performance.

| APPLICATIONS |
|
Recording - Obtain the "layered" sound necessary for a clean mix |
|
Nightclubs and Discos - Increase perceived average level without increasing gain |
|
Sound Reinforcement - Control dynamics and peaks to prevent overload |
|
Karaoke - Helps keep singers audible and "even" in the mix |
|
Stage Monitors - Keep the audio "up front", without running out of headroom |
|
Tape Duplication - Maximize signal to noise ratio |
|
Musicians Rigs - Get a consistent sound without losing the edge |
|
Video - Get consistent audio every time for a more professional result |
|
Broadcast Production - Works as an invisible gain rider for consistent sounding spots |

1.
|
The DRIVE CONTROL adjusts input gain. Since the 108 has a fixed threshold, DRIVE not only sets the input
sensitivity, it also drives the amount of compression action as it is adjusted clockwise |
|
| 2. |
The GAIN REDUCTION meter is a 10 segment LED bar indicating 2dB of gain reduction per segment for a maximum
of 20dB. |
|
| 3. |
When the PROCESS IN/OUT SWITCH is IN, the Easyrider circuit is engaged. Process OUT is a hardwire bypass. |
|
| 4. |
The SPEED CONTROL adjusts the range of release times. |
|
| 5. |
The OUTPUT CONTROL sets the output level after the desired amount of compression is set by the Drive control. |
|
| 6. |
The POWER INDICATOR LED confirms power is connected to the unit. |
|
| 7. |
Engage the STEREO LINK switch to link the VCA's in channels one and two. In this mode, the channel that
has the most compression forces the same amount of gain reduction in the other channel. |
