The IO5-D/e inline channel has two independent equalizers. EQ 1 combines three fully parametric bands and a HI-LOW EQ, while EQ 2 is a 3 band version with a fully parametric MID band. The gain control range is +/- 20 dB for all Bands.The fully parametric bands use the acitve 'Vienna Robinson' bridge principle that offers outstanding, distortion free, sound performance.


Inline Channel 5MT Series D

Dual Equalizer

The Inline Channel IO5-D/e has two separate equalizer sections. The first EQ is the same 5 band split equalizer that is used with the IO5-D/c inline module. Equalizer two is a 3 band version with a fully parametric mid band. The two equalizers can be arranged in many different ways. While the EQ2 is a separate section with own REC and bypass switches, the split function of the 5 band equalizer makes possible to use the 5 bands as two, independent equalizers.

Both equalizers of the IO5-D/e inline channel offer outstanding sound performance. Each EQ combines an effective Hi-Low EQ with fully parametric bands that are based on the active Vienna Robinson bridge principle. This principle results in a distortion free treatment, also with extreme settings.

The three mid bands of EQ1 cover the entire audio range from 30 Hz to 20 kHz. The sweep range of the bands are overlapping. This makes is possible to use at least 2 of the bands in the same frequency range. All bands have a gain range of +/- 20 dB. The Q factor can be adjusted from smaller than a third to wider than 3 octaves. The frequency range of the low mid band is from 30 Hz to 2 kHz, the second band can be tuned from 60 Hz to 7 kHz and the high mid band has a range from 300 Hz to 20 kHz. These large ranges make it possible to modify the signal in every desired way. The mid band of EQ2 matches the MID2 band of EQ1.

The fully parametric bands are combined with a Hi band and a Low band Equalizer. These bands have also gain control ranges of +/- 20 dB. The default mode of the HI EQ is a low slope shelving curve that reaches its maximum above 15 kHz. This mode produces very nice, silky sounds. The 8 kHz switch selects a very soft bell type character for the HI eq, that has a center frequency of 8 kHz.

The Low EQ is always a soft bell type filter. This principle avoids that subsonic frequencies are increased by the low EQ. It is therefore not necessary to use the high pass filter to reduce subsonic interference when the low EQ is used with high gain settings. Two center frequencies can be selected by a switch; 60 Hz and 100 Hz.

Each equalizer is switched into the signal chain by its EQ switch. When the Split function is active, the EQ switch bypasses the Hi-Low section while the SPLIT OFF switch bypasses the 3 band EQ. In Split mode, any combination of the 3 equalizers is possible. Each EQ can be switched to the tape or record chain independly.
