MONO INPUT CHANNELS
1Gain
This control establishes the nominal operating level for the channel. The input gain can be adjusted over a wide range (0 dB – 60 dB) to compensate for soft voices or very loud drums. To maximize the signal-to-noise ratio, the gain should be set to the proper level, with the Channel Fader (13) set to 0. It can be set by pressing the PFL Switch (12) and adjusting for 0 dB on the output meter. If the clip LED comes on and remains lit, reduce the gain.
2Lo Cut
The low-cut filter has a corner frequency of 75 Hz. When engaged‚ it can improve clarity by removing low frequencies that make a mix sound muddy. This filter reduces handling and stage noise, breathing noise, and unwanted low frequency energy that can rob your sound system of power. Engaging this switch will remove those frequencies from the system and restore power where needed. We recommend engaging it for all channels except those with the lowest bass tones such as Bass guitar and Kick drum.
3Hi EQ
This shelving type tone control adjusts treble frequency levels (±15 dB at 10 KHz), resulting in less noise or more brilliance.
4Mid EQ
This active tone control is a bandpass (peak/notch) type that varies mid-fre- quency response by ±15 dB in a range from 100 Hz to 5 kHz. The center frequency is controlled by the Mid Freq (5) control.
5Mid Freq
This control determines the center frequency of the Mid EQ (4) control. Center frequency for the bandpass filter can be set from 100 Hz to 5 kHz.
6Low EQ
This shelving-type tone control adjusts bass frequency levels (±15 dB at 70 Hz), adding depth to thin signals or clarity to overly thick signals.
Caution: Excessive low frequency boost causes increased power consumption and increases the possibility of speaker damage.
7AUX 1-4 Sends
These controls send the channel’s pre-fader, post-EQ signal to each of four aux buses. These buses are normally used for monitor sends or for feeding a sepa- rate mix to external equipment. There are internal jumpers that can be switched to change the send point to pre-EQ. Unity gain is at the center detent position with up to 10 dB of gain in the fully clockwise position.
8AUX 5-6/EFX 1-2 Sends
These controls send the channel’s post-fader signal to each of two aux (effects) buses. These buses are normally used for effects sends or for feeding the inter- nal effects processors. Unity gain is at the center detent position with up to 10 dB of gain in the fully clockwise position.
