Mix Functions The IMX644 mix functions can be programmed and edited in detail using the IMX644 Manager installed on a computer (page 7). The mix functions that can be controlled by the IMX644 Manager application are discussed in this section. For operating details refer to the IMX644 Manager Owner's Manual. To enable communication with the IMX644 Manager application, press and hold the IMX644 MEMORY [D] button while turning the [POWER] switch ON. Input Channels ■ GAIN The gain of the mono input channel head amplifiers can be individually adjusted and displayed. Parameter GAIN (PAD is off) GAIN (PAD is ON) Range -54dB - -30dB -20dB - +4dB Initial value -35dB -1dB ■ INPUT EQ The parameters of the input channel equalizers can be individually adjusted and displayed. The parameters available for each channel are listed below. MONO INPUT CHANNEL Parameter G HIGH F G MID F Q G LOW F Range -15dB - +15dB 2kHz - 18kHz -15dB - +15dB 40Hz - 18kHz 0.5 - 12.0 -15dB - +15dB 40Hz - 2kHz Initial value 0dB 10kHz 0dB 2kHz 0.7 0dB 100Hz STEREO INPUT CHANNEL Parameter G HIGH F G LOW F Range -15dB - +15dB 2kHz - 18kHz -15dB - +15dB 40Hz - 2kHz Initial value 0dB 10kHz 0dB 100Hz ■ MATRIX The MATRIX allows individual input channels to be assigned to any of the mixer's output channels. The assignments are shown on the display. The initial default settings are: send assignments to all output channels are ON, with only OUT1 assigned to the REC OUT channel. The send levels from individual mono input channels to the output channels can also be adjusted and displayed. Parameter SEND LEVEL Range -∞ - 0dB Initial value 0dB ■ Temporary Matrix Assignment Changes The panel controls can be used to temporarily turn on the output assignments of individual input channels, as follows. 1 Set all OUTPUT channel level controls to "0". 2 Set the level of the INPUT channel to be assigned to "10". 3 Press and hold the MEMORY button correspond- ing to the output channel you want to assign the input channel to for longer than 3 seconds while rotating the INPUT channel level control towards "0". Button A B C D Output channel OUTPUT 1 OUTPUT 2 OUTPUT 3 OUTPUT 4 4 The corresponding MATRIX indicator will light. 5 Repeat for other channels as required. NOTE • Output assignments made in this way are only temporary and will not be saved to memory. If power to the unit is turned OFF and then ON again the memorized settings prior to making the changes as described above will be recalled. IMX644 Owner's Manual 15
