3 Features The Tube Channel is a unique product. It contains three independent award-winning circuit designs: one of the finest tube microphone preamplifiers available, one of the finest optical tube compressors available, and one of the most flexible EQs you’ve ever used -- all in one unit.
4 flexible collection of circuits. Mixer manufacturers need to make trade-offs to keep prices down while keeping performance up. Imagine the price of your mixer if each channels’ EQ cost over $200 (.
5 signal, it was designed to excel in areas where transparent and musical dynamics control is desired. The beauty of the optical design is its ability to apply heavy amounts of compression without pumping and breathing like VCA-based compressors. In many cases you will hear the results of the compression without hearing the compressor.
6 unbalanced connectors. We recommend using only high-quality cables equipped with the appropriate connectors. Installation The Tube Channel may be employed in a number of setups including:- Between a microphone and a mixer, digital multi-track recorder, DAT machine, hard disk recorder, or analog recorder.
7 Front P anel Contr ols & Indicator s Preamp Circuit Gain Control The Gain control sets the amount of input gain of the Tube Channel. Turn the control clockwise to increase gain and counterclockwise to decrease gain. Selection of the gain range is made with the +20dB gain switch.
8 microphones to the Tube Channel. Note: Be sure to turn down or mute the output of the Tube Channel when engaging or disengaging phantom power. Additionally, when disengaging, allow 30 - 45 seconds for the power to completely dissipate.
9 When setting up the preamp circuit, start with the Preamp Output at its “0” level. Once you get the Gain control set the way you want it to sound, use the Preamp Output control to set the level out of the preamp circuit (much like using the master volume control on a guitar amplifier).
10 (bypass) position, signal is allowed to pass from the preamp circuitry to the equalizer circuit with no compression. The LED will glow red when Bypass is engaged. This informs you that the compressor is bypassed. In its “out” (Norm) position, the compressor is active.
11 When the control is fully counter-clockwise, the output is attenuated by –20dB. Turning the control clockwise increases the level to a maximum of +20dB of gain. While you can use the compressor to add gain to a signal, it is better to add gain before the compressor for the best signal to noise ratio.
12 position the corner is 120Hz. Lo-Mid Frequency Control The Lo-Mid control is a dual concentric pot (there are two controls-- one outer and one inner). The outer control is used to select a frequency while the inner control is used to apply +/-12dB of gain.
13 The High Frequency control has as range of +/- 12dB. The two ranges are selected with the High Shift switch. 6KHz is great for adding top end to guitars, snare drums and vocals. Cutting 6KHz can also help to “take the edge off” brittle or harsh sounding instruments.
14 Tube Channel’s XLR Output jack. The Phase switch also reverses the polarity of the ¼” Output jack. In the Normal (out) position, the signal is in-phase. In the Reverse (in) position, the polarity of Pins 2 and 3 (and the Tip of the ¼” jack) are reversed and the signal is changed to 180 degrees out of phase with the input signal.
15 Rear P anel Connecti ons Input and Output Connections The Tube Channel’s XLR connectors follow the AES standard: Pin 1 = Ground, Pin 2 = Hot (+), Pin 3 = Cold (-). The unbalanced ¼” phone jacks are typical Tip = Hot (+), Sleeve = Ground. Input One input jack per channel should be used at a time.
16 signal paths from specific sections. The connections are unbalanced ¼” (Tip = Hot (+), Sleeve = Ground). Both of the “send” jacks may be used without interrupting signal-flow through the Tube Channel. The “return” jacks break the signal-flow when a jack is inserted.
17 the following for an output: Plug the output from the Preamp Send jack into the input of the next piece of equipment, - or - bypass the compressor and equalizer circuits and connect either of the Output Jacks to the input of the next piece of equipment.
18 Note: Be certain that you do not connect the Tube Channel’s XLR Output to a mixer input that has Phantom Power applied. The Tube Channel has enough gain to be used in front of a power amplifier.
19 EQ Tips What is the best way to use EQ? There are two schools of thought on EQ: 1) Use as much as you need to make things sound good. 2) Don’t use any EQ. Most people follow the suggestion of “if it sounds good, it is good.” You need to use your ears and judge for yourself as their are no steadfast rules for EQing.
20 frequency. You’ll have to adjust the level of the instrument depending on how much you cut, but you should find that with the “problem area” pulled out, the instrument works better in the mix.When recording EQ’d instruments you want to make sure you have good representation of frequencies on tape.
