ततः श्वेतैर्हयैर्युक्ते महति स्यन्दने स्थितौ । माधवः पाण्डवश्चैव दिव्यौ शङ्खौ प्रदध्मतुः ॥
tataḥ śvetair hayair yukte mahati syandane sthitau mādhavaḥ pāṇḍavaś caiva divyau śaṅkhau pradadhmatuḥ
Translation
Then, stationed in their great war-chariot, yoked to white horses, Mâdhava and the son of Pându blew their divine conches.

Explanation
Krishna (“Mâdhava”) and Arjuna answer from their own chariot, set apart from the general din by the word “divine” (divyau) attached to their conches specifically. It’s the first time in the chapter these two are named together as a pair, sharing one chariot — the vantage point from which the rest of the scene, and the rest of the Gita, unfolds.
