CHAPTER 22. SETTING THE OUTPUT LEVEL CORRECTLY.
The Crumar Seven features a pair of balanced TRS jack outputs that also support unbalanced connections. Connect your amplification
system to this stereo output and adjust the output level selector according to your needs.
Obtaining the best performance from the analog outputs
The Seven features a 3-way switch that lets you select the preferred sound level.
1. L = Low = -10 dB. Use this selection if you are connecting the Seven to other -10dB (consumer level) equipment such as a home
hi-fi system using unbalanced cables; this level should also be used if you intend to connect the Seven to a guitar or bass amp
with a “HI” input (usually dedicated to a preamplified guitar or bass).
2. M = Middle = +4 dB. Use this selection when connecting the Seven to a professional level equipment (mixers, powered amps or
speakers, etc.) and preferably use only balanced cables, which will guarantee a cleaner signal as well an average of 6 dB gain over
unbalanced cables. If you're connecting the Seven to a professional mixer, adjust the gain knobs so that the +4 dB input level is
well matched, in order to reduce the noise floor and obtain the highest S/N ratio possible.
3. H = High = about +10 dB. This selection should only be used when connecting the Seven to some very old amplification system
with a particularly low input impedance or weak preamplification. Beware: using this selection with normal professional or
consumer level equipment might increase the sound level as well as the noise floor, resulting in a noisy or distorted sound.
