User manual PEAVEY AUTO-MATCH

[. . . ] Each channel provides a gain control, 48 Volt phantom power (mic inputs), low cut filter, activity/clipping LED, an Aux send control and a choice between manual or automatic operation. Each channel also provides a defeatable insert point, 5 Volt TTL status output and can be muted individually or multiple channels can be muted simultaneously via an assignable mutebus. in addition , channels one and two provide an adjustable priority control. The master section provides a gain trim control, three 1/9 octave sweepable notch filters, a downward expander, transformer balanced outputs (main and aux) and remote volume connections. [. . . ] DIRECT OUTPUTS Each channel has direct output terminals that can be used for recording or anytime the output of an individual channel is required. MUTE Channels can be muted individually by shorting this terminal to ground. STATUS OUTPUT The status output is a DC logic output that is high (+5 Volts) when the channel is active and low (0Volts) when the channel is not active. This DC voltage can be used to key video cameras or trigger key lights on active microphones. MAIN OUT The main output is a 600½, transformer balanced output that can be used to feed an external power amplifier. AUX OUT The aux output is a 600½, transformer balanced output that can be used as an additional non-automixed output. REMOTE VOLUME The master level of the mixer can be controlled remotely with a simple connection on the back of the unit. If desired, a control voltage can be inserted to command 0 to 70dB of attenuation. MUTEBUS The mutebus is a control port that when shorted to ground will mute all channels that are assigned to the mutebus approximately 45dB. The channels to be muted must be assigned to the mutebus using the internal switch marked OFF/MBUS. see INTERNAL PANEL FEATURES , page 4 and diagram page 7. Connect a mic or line input to the first channel. While someone is speaking into the mic (in a way that it would normally be used), slowly increase the channel gain trim until a slight ringing (feedback) is heard or until the clip led begins to blink red occasionally. Turn the channel gain trim down slowly until the ringing is no longer audible. This is the maximum level that the gain trim should be set. Turn the external channel level control down (full CCW). NOTE: The internal master gain trim (#10) may need to be turned up (CW) if the channels can be easily driven into clipping, or feedback cannot be obtained in the normal operating range of the internal gain trim control. repeat this step for the remaining channels. Return all of the external channel levels controls to their mid position (12 oÕclock). It can be set using test equipment to pinpoint frequencies that are prone to feedback, or it can be set Òby ear. Ó For the purpose of this manual, the Òby earÓ method will be described: A. Slowly increase the master gain trim (internal) until a slight ringing is audible.
