These features also allow for ease of installation by the contractor without the need for custom work. GENERAL FEATURES • Automatic gating with NOM attenuation • Designed specifically for room combining applications • Vca override or mute for emergency paging • Four electronically balanced microphone/line inputs • One unbalanced auxiliary line level input • Separate input for background music • Separate input for paging • Bass and treble controls on 2 inputs • Adjustable "OFF” attenuation on each channel • Adjustable release time • Direct channel outputs — pre- and post-gate • Remote control of master level • Remote control of auxiliary input • Remote control of each channel (2505 only) Off Attn.

These five inputs include four switchable (mic/line) electronically balanced, automatic gating inputs with bass and treble controls on two channels and one non-gating unbalanced auxiliary line input. The sixth and seventh inputs are special. One input is specifically intended for background music applications It is a fixed gain, 50 k ohm, unbalanced, line level input, with remote on/off capability. It can be mixed with the other channels either before or after the master volume control. When mixed after the volume control, all other signals may be completely muted, or simply "ducked", during the page. This feature was designed with emergency paging applications in mind The seventh input is designed for paging applications. ROOM COMBINING FEATURES One of the applications the 2504 and 2505 are specifically designed to fulfill is the combining of sound systems in mu tiple meeting rooms. For example: a hotel has a complex of eight meeting rooms of various sizes. At times all meeting rooms are used independently of one another, while at other times movable partitions between rooms are opened, to create one large room. Of course, any combination of rooms can also occur. The 2504 and 2505 can be combined with other 2504 or 2505s to effect room combining. A complete line of room combining accessories greatly enhance the power of the 2504 or 2505 automatic mixer When 2504s or 2505s are combined, all automatic functions such as NOM and THRESHOLD are also combined. “LAST ON" The 2504 and 2505 have a feature called "Last On". This feature may be activated by installing a wire jumper on the terminal board used with the mixer. So what exactly does the "Last On" function do? Very simply: the last microphone that was gated on automatically, remains on until another microphone is gated on to take its place. This means that at least one microphone is always on in the room. This has many benefits in recording meetings or in teleconferencing. ' Last On" will allow several microphones to be on at the same time if dictated by microphone usage. ADDITIONAL FEATURES The 2504 and 2505 can be ganged with other 2504 or 2505s t...
