[. . . ] They are impedance-independent, so the frequency response remains constant whether the mic preamp is presented with an extremely high- or low-impedance load. Additionally, each channel has its own switchable low-cut filter (18 dB/octave @ 75 Hz). The mono channel EQs provide a range of ±15 dB at the following frequencies: 12 kHz shelving high-frequency EQ, 100 Hz to 8 kHz sweepable peaking mid-frequency EQ, and 80 Hz shelving low-frequency EQ. The stereo channels (21-24) provide ±15 dB of boost and cut at the following frequencies: 12 kHz shelving high-frequency EQ, 3 kHz peaking high-mid frequency EQ, 800 Hz peaking low-mid frequency EQ, and 80 Hz shelving low-frequency EQ.

[. . . ] The stereo input channels shall be capable of accepting either stereo or monaural line-level signals, and shall be fitted with stereo trim, equalization, balance, and auxiliary send controls; solo, mute and bus assign switches; and level indicating LEDs. The submix outputs shall each have level, pan, and "air" controls; solo and assign switches; and a bus access insert jack. The main outputs shall share a stereo master output fader and shall be fitted with insert jacks. Additionally, the mixer shall include a pre-fader/post fader solo function, a main monaural output with level control derived from the main stereo outputs, 6 monitor/effects send outputs, 4 stereo effects return inputs with switching and control functions, 1 stereo control room monitor output, 2 stereo headphone outputs, 1 set of stereo tape recorder convenience outputs, and 1 set of stereo tape monitor inputs. All necessary operating voltages for the mixer shall be provided by an internal power supply. Each monaural channel (1-28) shall include an XDRTM (Extended Dynamic Range) electronically balanced microphone input, using an XLR-3-F-type connector, accepting nominal levels from ­60 dBu to +4 dBu via a rotary Trim control. Phantom power shall be globally controlled via a rocker-type switch. Each monaural input channel shall also have an electronically balanced line level input, accommodating a nominal line level of between ­10 dBV and +4 dBu, and appearing on the rear panel as a 1/4" TRS phone jack. Each stereo input channel shall have left and right electronically balanced line level input, accommodating a nominal line level of between ­10 dBV and +4 dBu, and appearing on the rear panel as 1/4" TRS phone jacks. These jacks shall be fitted with internal switching contacts to accommodate monaural configuration. Additionally, each of the monaural input channels (1-28) shall offer an unbalanced insert connection, appearing on the rear panel as a 1/4" TRS phone jack. INPUT CHANNEL LEVEL AND ASSIGNMENT CONTROLS AND INDICATORS. Each monaural input channel shall be equipped with a preamplifier gain control, a solo switch, a mute switch, three bus assignment switches, and a stereo pan control. Each stereo input channel shall be equipped with a dual preamplifier gain control, a solo switch, a mute switch, three bus assignment switches and a stereo balance control. Each monaural input channel shall be equipped with an equalization function. The equalizer shall have three sections: a lowfrequency shelving equalizer with the knee set at 80 Hz and a range of +15 dB; a mid-frequency peaking equalizer with a center frequency sweepable from a range of 100 Hz to 8 kHz, and a range of +15 dB; and a high-frequency shelving equalizer with the knee set at 12 kHz and a range of +15 dB. Each stereo input channel shall be equipped with a stereo equalization function. The equalizer shall have four sections: a low-frequency shelving equalizer with the knee set at 80 Hz and a range of +15 dB; a low-mid-frequency peaking equalizer centered at 800 Hz and a range of +15 dB; a high-mid-frequency peaking equalizer centered at 3. 5 kHz and a range of +15 dB; and a high frequency shelving equalizer with the knee set at 12 kHz and a range of +15 dB. Each mixer input channel shall have 6 monaural auxiliary send controls. Two auxiliary send controls shall be fixed as prefader sends; two shall be fixed as post-fader sends; and two shall be switchable between pre-fader and post-fader. All auxiliary sends shall be post-mute switch. The mixer shall have electronically balanced, line-level left and right main outputs, appearing on male XLR-3 type connectors and impedance balanced on 1/4" phone TRS jacks on the rear panel. [. . . ] In addition to specifications previously cited, the mixer shall meet or exceed the following specifications. Frequency response, microphone input to any output, 20 kHz to 60 kHz, +0 dB/ ­1 dB; Total Harmonic Distortion (THD), any input to any output, 1 kHz @ +14dBu, 0. 004%; Equivalent Input Noise (EIN), microphone input to insert send, ­129. 5 dBm; Common Mode Rejection (CMR), microphone input to insert send, maximum gain, 1 kHz, better than 90 dB; Typical Main Output noise, all channels assigned, odd channels panned left, even channels panned right, all faders down ­94. 7 dBu; Signal to Noise ratio, ref +4 dBu operating level, 90 dB; Attenuation, ref. 0 dB @ 1 kHz, Main Mix level control down, ­85 dBu; Channel Mute engaged, ­84 dBu; Channel Gain control down, ­83 dBu; Input impedance, microphone inputs, 1. 5 k; Channel Insert return, 2. 5 k; all other inputs, greater than 10 k; Output impedance, Tape Out, 1. 1 k; All other outputs, 120. The mixer shall be a Mackie SR32·4-VLZ PRO. SR32·4-VLZ PRO Electronic files for this product available at: www. mackie. com/installed This Specification Sheet Owner/Operator's Manual SR32VLZPRO_SS.
